Bosch buys solid state battery start-up Seeo

German industrial conglomerate Bosch is acquiring Silicon Valley battery firm Seeo, including all of its intellectual property and research staff. With the move, Bosch is looking to enhance its offer to the electric car industry, which is witnessing a significant growth.

Founded in 2007, Seeo is known for its advancements in creating high-energy rechargeable lithium-ion batteries based on a nano-structured polymer electrolyte. Seeo uses solid state technology that avoids the use of flammable liquid electrolyte.

Using solid electrolyte, Seeo manufactures DryLyte batteries that deliver high energy density alongside impressive reliability and safety. Seeo has an exclusive license to core patents from Lawrence Berkeley National Laboratory and has more than 30 issued, exclusively licensed and pending patent applications.

News website Quartz reported that Bosch confirmed the acquisition. A Bosch spokeswoman told the website that the financial terms of the deal will not be released.

In December, Seeo made news as its CEO Hal Zarem announced plans to manufacture a battery with an energy density that is about double that of existing commercial lithium-ion batteries. The new battery would have a density of 300 watt hours per kg.

Bosch, which is already supplying a lot of components to the automobile industry, has long been looking to enter the advanced battery market. The acquisition may prove successful, as Seeo and its innovations are said to be of great potential.

Meanwhile, Seeo faces intense competition from start-ups such as Sakti3, QuantumScape, XG Sciences, Envia Systems and SolidEnergy Systems that are working on new types of electric car batteries. Panasonic is currently the leading player in the electric car battery market with a 39% market share, followed by LG Chem and Samsung SDI, according to research firm Lux Research.

UK To Test Dynamic Wireless Charging For Electric Cars

Trials of technology needed to power electric and hybrid vehicles wirelessly on England’s major roads are due to take place later this year.

The trials are the first of their kind and will test how the technology would work safely and effectively on the country’s motorways and major A roads, allowing drivers of ultra-low emission vehicles to travel long distances without needing to stop and charge the car’s battery.

The trials follow the completion of the feasibility study commissioned by Highways England into ‘dynamic wireless power transfer’ technologies.

Transport Minister Andrew Jones said:

The potential to recharge low emission vehicles on the move offers exciting possibilities. The government is already committing £500 million over the next five years to keep Britain at the forefront of this technology, which will help boost jobs and growth in the sector. As this study shows, we continue to explore options on how to improve journeys and make low-emission vehicles accessible to families and businesses.

Highways England Chief Highways Engineer Mike Wilson said:

Vehicle technologies are advancing at an ever increasing pace and we’re committed to supporting the growth of ultra-low emissions vehicles on our England’s motorways and major A roads.

The off road trials of wireless power technology will help to create a more sustainable road network for England and open up new opportunities for businesses that transport goods across the country.

The trials are expected to begin later this year following the completion of an ongoing procurement process. The trials will involve fitting vehicles with wireless technology and testing the equipment, installed underneath the road, to replicate motorway conditions. Full details of the trials will be publicised when a successful contractor has been appointed.

The trials are expected to last for approximately 18 months and, subject to the results, could be followed by on road trials.

As well as investigating the potential to install technology to wirelessly power ultra-low efficient vehicles, Highways England is also committed in the longer-term to installing plug-in charging points every 20 miles on the motorway network as part of the government’s Road Investment Strategy.

World’s Fastest Charging Electric Bus Takes 10 seconds to Charge

The world's fastest charging electric busses, that takes just 10 seconds to be fully charged, were put into operation for the first time in Ningbo on Tuesday.

The bus operates a 11-km route with 24 stops in Ningbo, Zhejiang province, local transport authorities said.

In the next three years, a total of 1,200 such buses will be used for public transport in the city, where the electric bus plant is located.

The bus recharges while stationary or while passengers get on or off, and each charge enables the bus to run for least five kilometers, according to Zhou Qinghe, president of Zhuzhou Electric Locomotive, a subsidiary of high-speed train maker CRRC.

In addition, the bus, which rolled off production line in April, consumes 30 to 50 percent less energy than other electric vehicles.

The capacitor can be charged one million times and has a 10-year life cycle.

BorgWarner to buy electric motor maker Remy for $950M

BorgWarner agreed to buy Remy for $951 million in cash, driving further consolidation of the auto-parts industry.

BorgWarner will pay $29.50 a share, a 44 percent premium from Remy’s closing price on Friday, according to a statement today. The price indicates an enterprise value of about $1.2 billion, BorgWarner said. The maker of turbochargers and transmission parts said the deal is set to close in the fourth quarter and should add to earnings in the first year because of purchasing efficiencies and other savings.

Demand for fuel-saving technology and global scale is pushing auto-parts makers to consolidate. In May, TRW Automotive Holdings Corp. was acquired by German auto supplier ZF Friedrichshafen AG for $12.4 billion.

“Our main focus has been organic growth, and that remains a prime path for us,” James Verrier, CEO of BorgWarner, said on a conference call. “But we’ve also been consistent about the need for M&A to add key technology to sustain that growth.”

The acquisition highlights the increasing importance of the electrification of the powertrain, which has not been a strength of BorgWarner’s, Verrier said.

BorgWarner rose 1 percent to $54.14 at 11:39 a.m. in New York, as Remy soared 42 percent to $29.18. This year through Friday, Remy had fallen 1.9 percent and BorgWarner had declined 2.4 percent.

Electric Powertrains

Buying Remy will add alternators, starters and hybrid motors, giving BorgWarner the ability to benefit as more powertrains blend electric power with traditional gasoline-fueled technology.

Some investors had been concerned that the move to hybrid engines would eventually cause BorgWarner to lose sales to automakers, Joseph Spak, an analyst with RBC Capital Markets, wrote in a research note today.

BorgWarner CFO Ron Hundzinski said he expects savings from the acquisition of at least $15 million annually within two years, in part by eliminating duplicate costs associated with a public company, and from lower purchasing expenses. He said he expects the Remy business to have profit margins in the mid-teens, similar to BorgWarner’s.

Former GM unit

Remy International, formerly known as Delco Remy, traces its roots to brothers Frank and Perry Remy, who developed magnetos, generators that used magnets to help start early automobiles. GM acquired Delco Remy in 1918 and spun it off in 1995. The name was changed to Remy International in 2004 and the Pendleton, Ind.-based company spent less than two months in bankruptcy in 2007.

Remy posted net income from continuing operations of $6.1 million last year on revenue of $1.2 billion. In 2013, it posted net income of $12.4 million on revenue of $1.1 billion.

Torque Vector Steering Improves Electric Vehicle Energy Efficiency

Germany's Karlsruhe Institute for Technology along with industry partner Schaeffler are researching improvements in electric vehicle energy efficiency by using brake steer or torque vector control of wheel motors to assist power steering.

The project "Intelligent Assisted Steering System with Optimum Energy Efficiency for Electric Vehicles (e²-Lenk)" subsidized by the Federal Ministry for Education and Research (BMBF) focuses on a new assisted steering concept. In conventional vehicles, the internal combustion engine not only accelerates the car but also supplies on-board assist systems with energy; such as the assisted steering system, which reduces the strain on the driver at the wheel.

In electric vehicles, this energy comes from the battery and also reduces the range as a result. In this research project by the collaborating partners, Karlsruhe Institute for Technology (KIT) and Schaeffler, the steering system is assisted in an energy-efficient manner by intelligent control of the drive torques transmitted to the individual wheels. The project is being sponsored by BMBF with a sum of around 0.6 million euros over 3 years and was started in January 2015.

"The new assisted steering system would require less system components in an electric vehicle, this would mean savings in terms of weight and energy in an electric vehicle", explain project managers Dr. Marcel Mayer, Schaeffler, and Dr. Michael Frey, KIT. "This would mean that an electric car would be cheaper and have a greater range." Materials and production steps can be saved due to the potential optimization of the design and weight.

The basic idea of the e²-Lenk project is simple: The wheels in an electric car will be driven individually by electric motors in contrast to a car with an internal combustion engine where all the wheels are provided with equal force. If the wheels on the left side transmit more drive torque to the road than those on the right side, this will result in acceleration of the vehicle to the right without the need to turn the front wheels or consume additional energy for steering.

Tracked vehicles or quadrocopters steer using the same principle. "Steering assistance can be provided while driving by means of an intelligent control system and suitable wheel suspension", says Schaeffler engineer Mayer, Manager of the Automatic Driving Working Group, which is carrying out research as part of the collaborative research project SHARE (Schaeffler Hub for Automotive Research in E-Mobility) at KIT. "Only steering when stationary remains a challenge with conventional designs."

"The assisted steering system is part of the drive train with our approach", explains Frey who is researching at KIT's Institute of Vehicle Systems Technology. Steering the front wheels is carried out without using additional energy. "We also want to significantly increase the quality of driving. Customer benefit, comfort, safety and reliability go hand in hand here."

As part of the project, functional demonstrators are being built, with which the concepts can be validated and optimized in experiments. It is also planned to implement the system in last year's Formula Student racing car KIT built by the university group KA-RaceIng with the participation of the students.

e²-Lenk is the first publicly subsidized joint project as part of the collaborative re-search project SHARE at KIT between Schaeffler Technologies AG & Co. KG and KIT. This joint project is being managed at KIT's East Campus in a joint project management office run by SHARE at KIT and the Institute of Vehicle Systems Technology (FAST).

Schaeffler and KIT are partners in the Leading Edge Cluster Electric Mobility South-West (ESW), which connects over 80 stakeholders from science and economics in the region Karlsruhe – Mannheim – Stuttgart – Ulm. The cluster strategy of the ESW cluster aims to achieve intensive regional collaboration in the field of electric mobility by means of new approaches and forms of cooperation. As a result, knowledge is developed, consolidated and ultimately advantages are achieved in international competition.

Axial Flux Induction Motor for Hybrid and Electric Cars [VIDEO]

EV Powertrain start-up Evans Electric is rumoured to have been working on some interesting electric vehicle projects recently.

The team have developed a world-first copper rotor axial flux induction motor for automotive applications. The patent pending design has torque density on par with comparable axial air gap synchronous motors but without the expense of rare-earth permanent magnets.

Disc-shaped Axial flux motors are steadily making inroads into electric vehicle powertrains with Renault, Koenigsegg and Bugatti all looking to incorporate them into future models.

Evans Electric were also rumoured to have been hired by an OEM to help develop the architecture of a series hybrid powertrain based on in-board AFIMs with all-wheel-drive torque vectoring powered by a supercapacitor / li-ion battery energy storage system.

No news on which OEMs head these projects but they are believed to be EU headquartered.

Carbon Fiber to Go Mainstream in Automobile by 2025

Driven by a faster-than-expected pace of technology development, carbon-fiber reinforced plastics (CFRPs) will be poised to gain widespread adoption for automotive lightweighting by 2025, according to Lux Research.

Already advances underway in fiber, resin and composite part production will lead to a $6 billion market for automotive CFRPs in 2020, more than double Lux's earlier projection. Even this figure is dwarfed by the full potential for CFRPs in automotive if they can become affordable enough for use in mainstream vehicles.

“Current trends strongly indicate significant mainstream automotive adoption of CFRPs in the mid-2020s, and companies throughout the value chain must position themselves to take advantage of the coming shifts. However, long-term megatrends towards urbanization, connectivity and automation suggest that there could be a limited time window beyond that for penetrating the automotive space,” said Anthony Vicari, Lux Research Associate and the lead author of the report titled, “Scaling Up Carbon Fiber: Roadmap to Automotive Adoption.”

“CFRP developers will have to continue the pace of innovation to overcome the high cost that has so far limited the material to less price-sensitive markets like aerospace and sporting goods,” he added.

Lux Research analysts reviewed the technology development in CFRPs, and evaluated its economics to consider its impact on the automotive sector. Among their findings:

  • Growing partnerships hasten development. The number of direct partnerships between carmakers or Tier-1 automotive suppliers and carbon fiber players has nearly doubled to 11 since 2012. Toray, with partnerships with Plasan Carbon Composites and Magna, has formed the most new relationships and is a major hub.

  • Patent uptick suggests mid-2020 adoption. Using a predictive tool, Lux Research identified a lag of about 18 years between uptick of patent activity and attainment of mainstream commercial adoption milestones. With another major upturn in CFRP patent activity occurring in 2007, large-scale mainstream automotive use is likely by the mid-2020s.

  • Other manufacturing costs need to be cut. Carbon fiber itself, at $28/kg for standard modulus fiber, represents just 22% of the cost of a final CFRP part. Additional advances are needed to reduce capital, labor, energy, resin and processing costs, which together make up the remaining 78%.

    Toyota to Trial New SiC Power Semiconductor Technology [VIDEO]

    Using a "Camry" hybrid prototype and a fuel cell bus, Toyota Motor Corporation will bring a brand new technology to the streets of Japan for testing this year. The tests will evaluate the performance of silicon carbide (SiC) power semiconductors, which could lead to significant efficiency improvements in hybrids and other vehicles with electric powertrains.

    Technology

    Power semiconductors are found in power control units (PCUs), which are used to control motor drive power in hybrids and other vehicles with electric powertrains. PCUs play a crucial role in the use of electricity, supplying battery power to the motors during operation and recharging the battery using energy recovered during deceleration.

    At present, power semiconductors account for approximately 20 percent of a vehicle's total electrical losses, meaning that raising the efficiency of the power semiconductors is a promising way to increase powertrain efficiency.

    By comparison with existing silicon power semiconductors, the newly developed high quality silicon carbide (SiC) power semiconductors create less resistance when electricity flows through them. The technologies behind these SiC power semiconductors were developed jointly by Toyota, Denso Corporation, and Toyota Central R&D Labs., Inc. as part of the results of a broader R&D project* in Japan.

    Test vehicles and period

    In the Camry hybrid prototype, Toyota is installing SiC power semiconductors (transistors and diodes) in the PCU's internal voltage step-up converter and the inverter that controls the motor. Data gathered will include PCU voltage and current as well as driving speeds, driving patterns, and conditions such as outside temperature. By comparing this information with data from silicon semiconductors currently in use, Toyota will assess the improvement to efficiency achieved by the new SiC power semiconductors. Road testing of the Camry prototype will begin (primarily in Toyota City) in early February 2015, and will continue for about one year.

    Similarly, on January 9, 2015, Toyota began collecting operating data from a fuel cell bus currently in regular commercial operation in Toyota City. The bus features SiC diodes in the fuel cell voltage step-up converter, which is used to control the voltage of electricity from the fuel cell stack.

    Data from testing will be reflected in development, with the goal of putting the new SiC power semiconductors into practical use as soon as possible.

    Carnegie Mellon Researchers Increase Lithium Air Battery Energy Capacity 5x

    Carnegie Mellon University's Venkat Viswanathan and a team of researchers have reduced the problem of sudden death in lithium air batteries through the addition of water, increasing energy storage capacity by five times.

    "We could not get all the energy out of these batteries because of sudden death," says Viswanathan, an assistant professor of Mechanical Engineering. "That was the ugly aspect of this battery."

    Lithium air batteries are an exciting research frontier because they could store at least twice as much energy as lithium ion batteries, which are currently the most common battery used in many consumer products, ranging from cell phones and laptops to electric vehicles. The potential of lithium air batteries lies in replacing one of the battery materials, the cathode, with air, making lithium air batteries lighter than lithium ion batteries. The lighter the battery, the more energy it can store. In addition, lithium air batteries have the possibility to increase safety.

    Viswanathan, IBM researchers Nagaphani B. Aetukuri, Jeannette M. García, and Leslie E. Krupp, University of California, Berkley Assistant Professor Bryan D. McCloskey and Alan C. Luntz of the SLAC National Accelerator Laboratory discovered that adding water to the battery decreases a phenomenon called sudden death, which reduces the battery's storage capacity. They published their results in Nature Chemistry.

    Sudden death causes lithium air batteries to die prematurely. The batteries require lithium, oxygen and an electron to move inside the battery to reach the active site where the reaction produces energy. As the battery operates, however, the lithium and oxygen form lithium peroxide films that produces a barrier and prevents electron movement to the active site, resulting in sudden death.

    Water selectively dissolves the lithium peroxide, and the dissolved lithium and oxygen move to a toroidal depository in the cathode, removing the barrier to electron movement, before reforming into lithium peroxide.

    "This allows for five times the capacity of the original case," says Aetukuri.

    While water is a temporary solution, it is eventually consumed and results in parasitic products that reduce battery efficiency. Viswanathan and McCloskey are currently searching for an additive other than water, which will result in increased battery capacity and efficiency. However, the addition of water is a large step forward in lithium air battery technology.

    "This additive opens up the opportunity to be able to reach a much higher energy density than a lithium ion battery, and once we perfect the design, we can compete with lithium ion batteries," says Viswanathan.
