Each car system referred to

Battery Management System BMS (Battery Management System)

    BMS is the link between the cell and the user. The main object is the secondary battery, is mainly possible to improve the utilization of the battery to prevent battery over-charging and over-discharge, it can be used in electric vehicles, electric vehicles, robots, unmanned aerial vehicles. In addition, BMS or computer game music files stored in a common format and telecommunications services management system name of a new generation.

OBC car charger (On Board Charger)

    Electric vehicle charging, the charger is not directly connected to large external battery, but the battery is charged by OBC to give electric vehicles, mainly played the role of a protection.

VCU VCU (Vehicle Control Unit)

     Electric vehicle controller is a core member of the electric vehicle control system, an electric vehicle is used to control the motor to start, run, forward and backward, speed, stop, and other electronic devices, the core of the electric vehicle control device. VCU as the core components of pure electric vehicle control system, its commitment to the exchange of data, security management, driver intent interpretation, energy flow management tasks.

    After the motor control system signal acquisition VCU, accelerator pedal signal, a brake pedal signal and the other signal components, and a comprehensive analysis is determined in response to a driver's driving intention in accordance with the monitoring operation of the various components of the controller of the lower layer, the normal running of the car, Regenerative braking battery power, network management, fault diagnosis and treatment, the vehicle state monitoring function plays a key role.

The electronic control unit ECU (Electronic Control Unit)

    Also commonly been called the Car PC computer or car, for the car ECU is equivalent to the human brain as the most popular is the words of ECU is the car's brain. And, like ordinary computer, ECU is a CPU, various memories and a plurality of interface.

The microcontroller MCU (Micro Controller Unit)

    Mainly to control the car in between the various peripheral circuits and interface circuits connected in temperature between 0-70 as civil level, now mainly lies in the study of MCU intelligent control capabilities highlights its object.

The hybrid vehicle controller HCU (Hybrid Control Unit)

    HCU as a master controller of the whole hybrid system, assume the energy distribution of the whole system, torque management, and other functions. HCU or ABS actuator, typically a pressure increasing valve (normally open valve), the pressure reducing valve (normally closed valve), back to the pump, the accumulator components.

PDU distribution box referred to as high-pressure distribution box (Power Distribution Unit)

   High-pressure system to solve new energy vehicles distribution unit high voltage power supply scheme. The high-voltage component is electrically connected by a busbar and the wire harness, there is provided charge and discharge control as a new energy vehicles high pressure system, high pressure components of the electrical control circuit overload and short circuit protection, a high-pressure sampling, a low-pressure control functions, protection and monitoring the high pressure system runs .

PDU master BMS functions can be integrated, the charging module, the DC module, the PTC control module, compared with the more traditional PDU vehicle function module, function more integrated, more complex structure, having a water-cooling or air cooling and the like The heat dissipation structure. PDU configuration flexibility, can be customized according to customer requirements development, to meet the needs of different customers different models. Currently PDU are customized according to the needs of the depot, so gather customer demand and customer vehicle electrical performance is very important.

Disconnect unit BDU battery pack (Battery Disconnect Unit)

    It is designed for the internal battery pack design, but also a distribution box.

CAN Controller Area Network (Controller Area Network)

    Is a research and development and production of automotive electronics products known to the German Bosch company to develop and eventually become the international standard (ISO 11898), is one of the most widely used international fieldbus. In North America and Western Europe, CAN bus protocol has become an automotive computer control systems and embedded industrial control LAN standard bus, and has a J1939 CAN protocol is the underlying protocol designed for large trucks and heavy machinery vehicles.
