DENSO and Toyota
For the stator, segment coil stator with distributed winding was developed and achieved weight reduction and copper loss reduction.
Hitachi Automotive Systems
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 solenoid valve is used to control hydraulic pressure and flow. Various types of solenoid valves are available, including linear, duty and on-off, depending on the controlled elements within the system and also with a view to various hydraulic systems.
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.
Use MOSFET for rectifying and inverting to improve efficiency
