Name: Electric controller Specification: 48V, 60V, 72V Type: Three-phase permanent magnet brushless

Name: Electric controllerSpecification: 48V, 60V, 72VType: Three-phase permanent magnet brushless

  Basic function

1,Failure detection could be finished by distinguishing the controller’s failure source via LED’s twinkling.

2,The built-in pre-charging circuit and over current detection

3,The controller have the self-measure and overheating protection function.

4,The controller would reduce the current automatically to protect the controller and battery when in high temperature environment.

5,To do the real time monitoring to the battery’s voltage. It would stop working when the battery voltage is too big and it would reduce the output current of the controller until stop working when battery voltage is too small.

6,The generating voltage of energy regeneration braking would be monitored by the controller.The charging current would be reduced at once by the controller when the voltage is too high.

7,Two options provided by the energy regeneration braking,that is, brake regeneration braking or regeneration braking generated without acceleration.

8,The maximum output voltage of the controller detected and controlled automatically so to avoid overcurrent.

9,The controller would stop the current outputting when fault command  which may infect the safety detected.

10,The speed would be limited automatically when the motor in a reversing working condition(or in another word, when the vehicle reversing).

11,The real time working condition of controller and EV could be displayed directly from the instrument cluster by connecting the wire to the connector of the instrument cluster of EV.

12,Provide pulse signal of the motor rotate speed.

13,3 nos switch input: Switch input of accelerator pedal position, switch input of footbrake and turning switch input.

14,One input of 0-4.8V accelerator signal.

 Features

1,Special designed for light four wheels EV.

2,Powerful and intelligent microprocessor

3, Efficient and low energy consumption PWM

4,Strict control for alternator current.

5,Bigger starting current, bigger starting torque.

6,Low electromagnetic interference, good performance of anti-interference and anti-vibration.

7,LED for indicating various fault code and convenient for user’s detect and maintenance.

8,Beautiful look of the housing made of aluminum in strip shape which have a good performance of heat emission.

9,Hall position sensor motor compatible with 60 degrees or 120 degrees.

10,Support permanent magnet brushless motors of any pole numbers.

11,It would detect the accelerator's input signal when controller’s start switch on. If accelerating signal detected, then the controller couldn’t work so as to ensure the safety.

Technical parameters

1,Working frequency: 15 KHz

2,Standby current: less than 100mA

3,Voltage and current of Motor rotor Hall sensor: 5V, less than 50mA

4,Nominal voltage: 48V  60V  72V

5,Controller operation voltage range: Nominal voltage ±25%.

6,Braking and accelerator signal input: braking voltage signal of 12V and continuous and variable signal of 0-4.8V.

7,Full power working environment range: -20°C —40 °C

8,Output current of the controller: 140A/200A/240A/300A/320A/370A different model, different current.

9,It would output 50% of limiting current and give fault code when the controller temperature reach 65°C and stop outputting the current when the interior temperature reach 85°C.

10,Motor rotate speed pulse signal output: amplitude≥10V, output load≥500Ω.
