Electric Tricycle Controller Built-in Speed Limit Sep 29, 2017

Electric Tricycle Controller Built-in speed limit

The built - in speed limit method of electric vehicle controller

1. Brakes turn the handle in the end, open the key, delay 6 seconds or so, release the brake turn it, you can!

Second, the above operation repeated twice, or directly pinch the brakes, turn it in the end, switch the key twice, delay 6 seconds or so, release the brake can turn it!

3. Push the brakes in the end, switch the key three times, release the brakes turn it!

4. Push the brakes in the end, open the key, delay 6 seconds, release the brake throttle, then add the door motor does not turn the key to turn off once again!

Five. Before opening the key can be brakes, or low speed,

6. Push the brakes in the end, open the key, turn it back home plus two in the end to keep 6 seconds to release!

7. Hold the brakes turn the bar in the end to open the key to hold the ride mode selection button delay 6 seconds or so, can be released, where the function selection button is actually another brake switch only, that is, you can use to hold the direct button Switch, turn it in the end, open the key to delay. Can be opened to restore the recovery method:

1. pinch the brake throttle in the end, open the key to turn it back to add the end of the second delay of about 6 seconds to release the brake throttle can return to the limit!

2, with the first way to recover, that is, the brake throttle plus in the end, open the key delay 6 seconds, release the brake throttle can!

3, pinch brake throttle in the end, open the key delay 6 seconds, release the brake to turn it to restore!

4, pinch the brakes, turn it in the end, open the key, delay 6 seconds, release the brake can turn it!

5, directly open the key for low speed!

6, push the brakes turn it in the end, open the key delay 6 seconds, release the brake turn it, re-switch the key can be! Controller refers to the control of the motor speed inside the electric car inside the important components, but also the core part of the electric car electric system, the main control motor speed, electric vehicle energy management system and a variety of core components of signal processing. In the electric car industry also requires the controller has a brake power, undervoltage protection, undervoltage recovery set over-current protection and other corresponding series of protection functions.

The electric vehicle controller can also be divided into a brushless controller and a brush controller. Brushless controller relies on electronic commutation, the complexity of the circuit is also much higher than the brush controller, so its manufacturing costs and process is much higher than the brush controller.

Brush controller detection method:

(1) Disconnect the power supply with diode check

A red pen connected to the controller power input positive, black pen then negative, charging phenomenon is normal, short circuit is damaged.

B red pen connected to the controller power input negative, black pen then red, yellow, green, short circuit is damaged.

C red pen connected to the controller power input negative, black pen connected to the motor negative should have 400-700 parameters.

D red table pen connected to the motor negative, black pen connected to the controller positive, should have 100-300 parameters.

E turn red, black, green, should not have short-circuit phenomenon.
