The batteries for the shared electric vehicle are lithium batteries, and need to be charged, but cannot be charged by one charger per vehicle like a household electric vehicle. Therefore, the mainstream mode of the current market is that an operator transports a fully charged battery pack to the address of the shared battery car, then uses the fully charged battery pack to replace a non-charged battery on the shared electric car, and then brings the replaced battery back to a special charging place for charging.

The charging control requirement of the lithium battery is higher than that of a lead-acid battery, the lithium battery needs constant-current and constant-voltage charging, a charging loop is disconnected after the lithium battery is fully charged, repeated charging is prevented, and lithium is easy to separate out due to overcharge of the lithium battery, lithium dendrites are generated (the lithium dendrites are dendritic metal lithium formed when lithium ions are reduced in the charging overcharge process), so that the electrode and electrolyte interface of the lithium battery is unstable in the charging and discharging process, and a generated Solid Electrolyte Interface (SEI) film is damaged. Lithium dendrites continuously consume electrolyte during growth and cause irreversible precipitation of metallic lithium, resulting in low coulombic efficiency. The lithium dendrites can even pierce through the membrane to cause short circuit inside the lithium battery, causing thermal runaway of the lithium battery to cause combustion explosion.
