The Function of Mobility Scooters
Brief Introduction of Mobility Scooters
The protection function is to prevent the over-discharge of the commutation power tube and power supply in the controller, and the elderly motor is running, which is caused by a certain fault or misoperation
When a fault such as damage that may be caused occurs, the circuit takes protective measures based on the feedback signal. The basic protection functions and extended functions of mobility scooters are as follows:
Contact Switch
The two caliper brake handlebars on the handlebars of elderly mobility scooters are equipped with contact switches. When braking, the switch is pushed closed or opened, and the original switch state is changed. This change formation signal is transmitted to the control circuit, and the circuit issues an instruction according to a preset program to immediately cut off the base drive current, cut off the power, and stop the power supply. Therefore, it not only protects the power tube itself, but also protects the elderly motor, and also prevents the waste of power supply.
Safety Protection
End-of-discharge voltage protection
This refers to the voltage of the power supply. When the final stage of discharge, under load, the power supply voltage is close to the "discharge end voltage", the controller panel (or instrument display panel) shows that the power is insufficient, causing the rider's attention to plan their own trip. When the power supply voltage has reached the end of the discharge, the voltage sampling resistor feeds the shunt information into the comparator, and the protection circuit issues a command according to a preset program to cut off the current to protect the electronic device and the power supply.
Current protection
Current overrun may damage or even burn a series of components of the motor and circuit, which should definitely be avoided. The control circuit must have this overcurrent protection function, and cut off the current after a certain delay when overcurrent occurs.
