The battery in the embodiments of this application may be applied to various electric apparatuses that use electrical energy as power. The electric apparatuses herein may be, but are not limited to, electric cars, electric trains, electric bicycles, golf carts, drones, ships, and the like. In addition, the electric apparatuses may be apparatuses that use only batteries to supply power, or may be hybrid electric apparatuses. The battery supplies electrical energy to the electric apparatus, and the electric apparatus is driven by a motor.

For example, FIG. 1-A is a schematic structural diagram of an electric apparatus according to an embodiment of the application, where the electric apparatus may be a vehicle. The vehicle may be a fossil fuel vehicle, a natural gas vehicle, or a new energy vehicle. The new energy vehicle may be a battery electric vehicle, a hybrid electric vehicle, a range-extended vehicle, or the like. The vehicle includes a battery 200, a controller 210, and a motor 220. The battery 200 is configured to supply electricity to the controller 210 and the motor 220 as an operating power source and a driving power source of the vehicle. For example, the battery 200 is configured to satisfy the need for electricity during start, navigation, and operation of the vehicle. For example, the battery 200 supplies electricity to the controller 210, and the controller 210 controls the battery 200 to supply electricity to the motor 220. The motor 220 receives and uses the electricity from the battery 200 as a driving power source of the vehicle, to replace or partially replace fuel or natural gas as a driving power of the vehicle.
