Abstract
A battery system includes a battery pack, an electrical interface and a load discharging the battery pack. The battery pack is used to provide a power supply and includes a monitor which is configured to monitor a battery status of the battery pack. The electrical interface is coupled to the battery pack for transmitting the power supply and the battery status. The load is coupled to the battery pack through the electrical interface, and receives the power supply to discharge the battery pack and receives the battery status via a first communication bus to control the discharging of the battery pack based on the battery status.
