With the development of new energy vehicles, the number of users is increasing. The biggest problem of new energy is battery. How to charge quickly has become a concern for everyone, and it is also one of the important indicators to measure whether to buy new energy vehicles. I think the future new energy vehicles should be the trend of changing electricity.
For changing electricity, it is impossible to change it by car, which not only wastes resources, but also cannot be popularized. So I think the future is more inclined to unify the largest battery compartment space. For example, the space size of the unified battery compartment is 2m *1m * 0.3m. All batteries produced by battery manufacturers adopt standard interfaces, which cannot exceed the maximum space of the battery compartment.
In this way, all new energy vehicles that meet this standard can be changed. In the future, gas stations will basically have power exchange services for new energy vehicles. According to the standard mentioned above, the owner only needs to drive in and change a fully charged battery in advance. So how to price it? First of all, if the replaced battery still has 30 kWh.
The replacement battery is 100 kWh, and the power station will automatically calculate: 100 kWh -30 kWh =70 kWh. In other words, the owner needs to pay according to 70 kWh. Assuming that the unit price is 1 yuan/kwh, the owner's charge for this electricity exchange is 70 yuan.
