Toshiba, in cooperation with Waseda University, has completed a year-long field test of electric buses equipped with its wireless rapid rechargeable battery system. In the test, a small and a medium-size bus, both customized to run on Toshiba’s SCiB batteries (the medium-size bus used a 52.9 kWh battery pack), provided regular service between All Nippon… Read more »

TDK and Toshiba establish joint venture for automotive inverters
Japanese conglomerates TDK and Toshiba have agreed to establish a joint venture to manufacture automotive inverters for hybrids, PHEVs and EVs. With an eye on the global trend toward stricter emissions regulations, TDK is strengthening its energy unit business, which centers on power conversion hardware, and the controlling software, for electrified vehicles. TDK’s line-up includes… Read more »
Toshiba launches new opto-isolated IGBT gate pre-driver IC for inverters
Toshiba’s new TB9150FNG, an opto-isolated Insulated Gate Bipolar Transistor (IGBT) gate pre-driver IC, features various enhanced protective functions for the inverters of electric and hybrid vehicles. As the control and drive functions of an inverter have different operating voltages, they must be isolated from each other. This is typically accomplished with a device such as… Read more »
Toshiba’s new motor control IC
Toshiba has begun mass production of a system regulator IC with monitoring function for motor control systems in electric and hybrid vehicles. The new IC (TB9042FTG) has a strengthened monitoring function to reduce potential system failures. TB9042FTG provides a Serial Peripheral Interface (SPI) communication function to avoid microcontroller (MCU) failures. The system regulator IC and… Read more »
Proterra to use Toshiba SCiB batteries in its next-generation electric bus
Proterra has selected Toshiba as the battery supplier for its next-generation electric bus. Toshiba’s SCiB batteries feature a lithium titanate oxide chemistry, making them resistant to thermal runaway and lithium metal plating. The 20 Ah prismatic cells have nominal voltage of 2.3 V, gravimetric energy density of 90 Wh/kg and volumetric density of 177 Wh/L…. Read more »
New magnetic material could improve EV motor efficiency
Toshiba has developed a new magnetic material with characteristics that could improve motor efficiency at low cost. Motors account for approximately half of the world’s electric power consumption. Toshiba says its new material boosts energy conversion efficiency when used as the wedges in motors, particularly in medium-to-large induction motors. The material can be installed at… Read more »
Proterra CEO on the economics of the electric bus business
Venture capitalists assume a large amount of risk when they invest in early-stage companies. They do so because of the potential for huge returns. To ensure that a portfolio of investments delivers the greatest return with the least risk, VCs spend a considerable amount of time evaluating companies, looking for the key ingredients of success….

Apple and A123 settle engineer-poaching lawsuit
The iCar is still just a rumor, but Apple surely has been showing a lot of interest in EV-related technology, including large-format batteries. This week, the Cupertino computer-maker agreed to settle a lawsuit alleging that it had been showing a little too much interest in engineers working for Massachusetts battery-maker A123. In February, A123 filed… Read more »
$30 million in Federal grants to pay for Proterra electric buses
The Federal Transit Administration FTA recently distributed $55 million in grants to 10 transit agencies as part of a program to deploy US-made electric transit buses. More than half of that money will be going to South Carolina-based Proterra, the Greenville News reported. Six transit agencies in five states will buy a total of 28… Read more »
Johnson Control introduces 12-volt lithium titanate battery for start-stop systems
Johnson Controls is adding a lithium titanate battery to its line of automotive battery offerings. The new 12-volt technology, the product of a collaboration with Toshiba, is designed to power Advanced Start-Stop vehicles. “Johnson Controls is pursuing opportunities to develop evolutionary low-voltage energy storage systems that will help our customers meet increasing fuel regulations at… Read more »
