Stall Protection Function Of Electric Scooter Controller
May 09, 2018

Stall protection function: Automatically judge whether the motor is in complete stall state or in running state or motor short-circuit state during overcurrent. If it is in running state during overcurrent, the controller will set the current limit value to a fixed value to keep The drive capability of the vehicle; if the motor is in a purely stalled state, the controller will limit the current limit to 10A or less after 2 seconds to protect the motor and battery and save power; if the motor is in a short-circuit state, the controller will make the output The current is controlled below 2A to ensure the safety of the controller and battery.

Active and static phase-failure protection: When the motor is running, if any phase of the electric motor has a phase failure, the controller will perform protection to prevent the motor from being burned, and at the same time protect the battery of the electric vehicle and extend the battery life.

Power tube dynamic protection function: When the controller is in dynamic operation, the power tube is monitored in real time. Once the power tube is damaged, the controller immediately implements protection to prevent damage to other power tubes due to the chain reaction. More laborious phenomenon.
