Detailed Description

Three-in-one controller: The three-in-one controller is referred to as INV2CON, APU (Auxilary Power Unit), also known as auxiliary power controller. It is an indispensable electric accessory for pure electric buses. Its functions include 1 DCDC (CONverter) and two Inverters (INVerter). DCDC converts the high-voltage electricity of the vehicle's high-voltage battery pack into the low-voltage electricity of the low-voltage system for the low-voltage control system to work. Two inverters drive two electric motors respectively, providing power sources for hydraulic power steering and braking systems.

Functions and features:

 The product adopts speed sensorless vector control technology and torque control technology that are synchronized with the current international advanced technology. It not only has the same excellent control performance as the international high-end inverter, but also combines the characteristics of China's application to further strengthen the reliability of the product Adaptability to the environment and the customized and industrialized design can better meet the needs of various transmission applications;

 The maximum efficiency at full load is over 95%;

Full digital control, with diagnostic function, can expand full digital CAN communication control;

 Over temperature, short circuit, over current and other protection functions are complete.
