Abstract:
A method and apparatus for detecting a connection state between a battery and a vehicle body, and a controller and a medium. The method comprises: detecting a contact resistance between one or more vehicle body fasteners and a battery to obtain a contact resistance detection value; and determining the connection state between the battery and the vehicle body according to the contact resistance detection value and a pre-set contact resistance threshold value. According to the method, by detecting a contact resistance between a battery and vehicle body fasteners, whether the fasteners are tightened in place is determined to further determine whether the battery is firmly installed. The detection process is simple, the detection result is reliable, the reliability and safety of power exchange are ensured, and safe driving of a vehicle with an exchangeable battery is ensured.
