Bender launches a new off-the-shelf automotive-grade isolation monitoring device for EVs

Traditional 12-volt automotive batteries are grounded to the metal chassis of vehicles for a few different reasons, mainly driven by cost. Using the metal frame as a common ground essentially reduces the number of wires needed for all of the 12-volt systems by half – saving money and reducing weight. For example, to power a… Read more »

Infineon’s HybridPACK DSC power modules for hybrid and electric vehicles

Infineon Technologies’ latest power module family features extremely small dimensions (42 x 42.4 x 4.77 mm). These modules are designed for applications such as main inverters and generators with a typical power range of 40 to 50 kW, and can be used in parallel configurations to support higher power levels. An inverter is typically placed… Read more »

Toyota R&D team improves free piston linear generators

Unlike a traditional ICE, which propels a drive shaft, a free piston engine linear generator (FPEG) is designed to generate electricity directly. Magnets attached to the piston move within a linear coil, converting kinetic energy to electrical energy. A team from Toyota Central R&D Labs presented a prototype FPEG to the SAE in 2014. Now… Read more »
