Product name: permanent magnet synchronous motor control system 70KW.

Product description:

Forward and reverse this controller has the electric car, such as throttle, brakes, hand brake signal input port, and connect instructs the running state of instrument signal output port, shall constitute a general electric vehicle drive and electric control system, also can cooperate with the electric car intelligent vehicle control unit (VCU) electrical system.

The controller system is embedded with excellent control algorithm, which improves the drive efficiency, and also realizes the control of energy feedback, effectively improving the range of the range. Therefore, the controller can be used in pure electric vehicles, logistics vehicles, sanitation vehicles, car racing, suvs, MPV, buses, China and Brazil, and large trucks.

Product Introduction

Function description:

● Fault protection function: in order to improve the safety of the electric car driving, set up multi-level fault protection measures, protection function includes: the motor overheating, overload, overcurrent, overload, drive motor drive drive overvoltage, drive voltage, the overheating, output phase tuning, communication fault, current detection, motor fault block, the encoder fault detection, EEPROM read and write, brake pedal fault and so on.

● Reverse speed limit function: for the purpose of safe driving, motor controller respectively for forward and backward to limit the top speed respectively, limit speed calibration according to the needs of vehicle dynamic performance.

● The gear error protection function: to avoid the high-speed operation of the vehicle in gear body appear when wrong operation flog, increase the comfort and safety of vehicles in the wrong operation, the cases, vehicles dropped below safe speed first, then new gear signal response.

● Anti-slip slope function: in order to improve the comfort of vehicle driving, the temporary stop of the vehicle in the ramp does not need to be braking by stepping on the brake and holding the handbrake, and also has a standing slope.

● Brake override functions: for security reasons, in order to prevent human or mechanical failure caused by wrong operation, set the brake motor controller signal priority is higher than drawing signal, namely on brake pedal and the accelerator pedal at the same time, the motor brake controller response signal, the signal does not respond to throttle.

● Operation sequence protection function: in order to ensure the normal start of the vehicle, the operation sequence must be the first gear to step on the gas pedal. The safety accident caused by the rapid acceleration caused by incorrect operation.

● Energy feedback function: when to slow down or brake, transfer the inertial energy through the transmission system of the car to the motor, the motor work in power generation way, for the battery charging, the inertial energy recycling, at the same time, the motor braking torque through the transmission system of driving wheel braking effect.

● Cruise control function: the driver use cruise control function, the motor controller by the torque control mode switch to speed control mode, according to a set of cruising speed control motor operation, automatically adjust the output torque, matching of load torque.

● Limit the power output function: according to the current running situation of the motor, the proper limits the size of a given torque, avoid lead to problems such as voltage saturation after motor in high speed motor oscillation phenomenon. At the same time avoid the power battery caused by excessive output power.
