In addition, when the electric vehicle runs in different application scenes, different working condition conditions need to be met, and because the output power required by different application scenes is different, the energy storage device is required to be suitable for different application scenes to output different power, for example, when the electric vehicle runs in a long-distance climbing state, high-power output needs to be provided for a long time, and the existing battery is limited by the high-power output and cannot meet the requirement; when an electric vehicle sunk in a pit is driven out of the pit, the energy storage equipment is required to output large power in a short time.
If the battery keeps working under the working condition of low discharge rate, the endurance time and the service life of the battery can be greatly improved.

The battery has the advantage of large energy storage capacity, but has the defect of slow charging and discharging, and the service life of the battery is greatly influenced when the battery is used for outputting high power.
