Batteries are very important components in energy storage systems. Terminals serve as the connection point between the battery and the external system, ensuring that the battery is able to transmit electrical energy in a stable and efficient manner. They are used to connect the positive and negative terminals of the battery to external circuits for storing and discharging electrical energy.

Terminals also play a safety protection role in the energy storage system. Some special terminal design can prevent the battery overcharge, overdischarge and other situations, thus improving the safety of the energy storage system.
