Expansion: Electric vehicle controller function:
1, dynamic and static open-phase protection: refers to the protection of the controller when any phase of the electric vehicle motor has a open-phase fault during operation, so as to prevent the motor from burning, and at the same time protect the electric vehicle battery and prolong its life.
2. Dynamic protection function of power tube: When the controller runs dynamically, it can monitor the working state of power tube in real time. Once the power tube is damaged, the controller will immediately implement protection to prevent other power tubes from being damaged due to chain reaction.
3. Anti-galloping function: It solves the controller galloping phenomenon caused by handlebar or line fault of brushless electric vehicle, and improves the security of the system.
