Brake disconnection is equivalent to the clutch of a motorcycle car. It just disconnects the power. It's a must. Generally, when the brake is pressed, the motor is cut off, and the throttle must be twisted again to start the motor.
Motor anti-tow braking is to add a circuit to the motor, and after the motor is powered off, it will automatically jump to this circuit. The motor is rotated to generate electricity and then the battery is recharged. If the motor carries a charging load, it will produce a resistance. You can slow down.
In theory, the motor anti-drag brake is better, but the effect is not obvious in actual use, and it is easy to break, resulting in circuit breakage, burning the battery, and the loss is not worth it. Not as easy as the first one.
It's not the same thing. Most of the current brake power failure is mechanical power failure, all controllers have. When the brake switch is closed, the circuit is switched on, the controller is given a signal, the control motor is powered off, the switch is opened when the release is made, the circuit is closed. EABS is an electronic brake system, some controllers have this function, some do not, and the power off the brake is not the same thing.
