 Function:

A. Protection function:

a.Self-checking protection: do real-time detection of brake handle, EABS system, hall and motor and itself to ensure safety and prolong lifetime.

b.Under voltage protection: the controller will stop working to protecting the battery, if the batteries’ voltage dropping to 87.5% of rated voltage.

c.Over-current protection: average current limit and peak current limit.

d.Blockage protection: Controller cut motor power off after 2 seconds in blockage

e.Runaway protection: prevent motor from runaway caused by the problem of throttle;

f. Soft start: Non-zero startup for user’s safety, soft and smooth acceleration during startup

 B. Use function (optional)

a. Speed limiting: the speed is within 20km/h.

b. Self-learning function:Automatically identify motor commutation angle, hall phase and output phase, saving the wiring trouble.

c. Cruise function: auto cruise and manual cruise for choose from, open cruise just  need 8 seconds, stable speed and non-handle control.

d. Drake: high level brake, low level brake or flexible E-ABS regenerative braking,Stop within 2 meters after braking ,as comfortable with the car.

e. Speed shifting function

f. 1:1 pedal assist function: give the same motor power according to the driver's pedal force, more relaxing for driver.

g. Back up function

h. Reverse charge function: charge the power produced from Brake, slow down or downhill slide to extend battery life, increase the line continuation mileage.
