For consumers of new energy vehicles, the power change mode is convenient and fast. According to the current average battery technology level in China, it takes nearly 8 hours to fully charge the battery in slow charging mode, and at least half an hour in fast charging mode. In contrast, the battery replacement can be completed in 3-10 minutes technically in the power change mode.

At the same time, the centralized and professional charging and discharging control is conducive to extending the service life of the battery, and the car owners need not worry about the life and quality of the battery. In addition, the power change mode can also be used in a large scale to concentrate on the late night off peak charging of low peak power, reducing the charging cost.

Large scale centralized charging of power stations can also reduce costs by using policies such as direct power purchase and peak and valley electricity prices to achieve win-win results. Due to the declining subsidies for new energy vehicles and the difficulty in breaking through battery technology in a short period of time, the more economical power exchange mode is expected to develop rapidly. Since a single car needs 1.3-1.8 times of backup batteries under the power change mode, the demand for lithium ion batteries will increase exponentially, and lithium battery industry chain companies will take the lead in benefiting.
