Abstract
A controller for a battery management system includes a first terminal, a second terminal, and communication circuitry. The first terminal receives power from a battery in the battery management system. The second terminal receives a clock signal. The communication circuitry coupled to the first and second terminals detects the clock signal, and generates a first switching signal according to a result of detecting the clock signal to control the battery management system to switch from operating in a ship mode to operating in a non-ship mode according to the first switching signal. The detecting and generating are performed with the battery management system in the ship mode. The battery management system disables controlling of charging and discharging of the battery in the ship mode, and the battery management system enables controlling of charging and discharging of the battery in the non-ship mode.
