Tesla to use prismatic cells for Chinese Model 3, says new report

From the beginning, Tesla’s use of readily available cylindrical battery cells gave it an advantage over other EV-makers, which used proprietary prismatic or pouch cells. In 2015, JB Straubel explained why Tesla was sticking with cylindrical cells, even though others found it a controversial decision. Over the years, many writers have noted Tesla’s battery tech… Read more »

Yamaha develops an electric motor prototype for EVs

Yamaha Motor has begun accepting orders for a high-performance electric motor prototype capable of producing high power density for EVs. The company says the compact unit generates up to 200 kW thanks to a high-efficiency segment conductor and advanced casting and processing technologies. Yamaha says the goal of the project is to deepen its knowledge… Read more »

ROHM’s new shunt resistors feature novel high heat dissipation structure

Semiconductor manufacturer ROHM has announced new shunt resistors ideal for current detection in motors and power supply circuits used in EVs and industrial equipment.
