For the stator, segment coil stator with distributed winding was developed and achieved weight reduction and copper loss reduction.

Flat cylindrical type intended to be built into the transmission or located between the engine and transmission. Used primarily in HEVs.

Coolant Heater for Battery and Cabin heating in xEV vehicles

Different designs of BorgWarner’s High Voltage Coolant Heater are suitable for application with supply voltages between 180 and 800V, offer a power range of between 3 and 10 kW, and are suitable for a broad range of applications.

DENSO developed a new high output density power card and a more efficient cooling structure. Compared with its installation in the previous Prius model, application of this advanced power control unit helps to reduce electric power loss by more than 20%.

The integration of control circuit, motor and pump enables a compact body size that achieves high compatibility to a variety of models. Optimized motor control reduces noise.
