Speed ​​up new energy Beijing pilot electric car battery replacement mode

The electric vehicle continues to try to change from "charging" to "changing." The National Development and Reform Commission announced yesterday that it will build an electric vehicle replacement service network in cities such as Beijing and Tianjin in the future, and the electric vehicle will continue to adopt the battery replacement mode.

This mode is mainly for battery replacement, supplemented by plug-in, centralized charging and unified delivery. Analysts said that this battery-changing model has a good prospect of profit, and can solve the problem of large area and high cost in the construction of charging stations. However, the promotion of larger-scale batteries still requires the unification of car battery standards.

“As long as the owner of an electric vehicle has opened an account in any of the networked charging and switching stations and receives a charge card, he can rent and use a fully charged battery, and replace the battery in any one of the networked charging and discharging stations quickly and easily, or in each At the networked AC charging piles, the cards are charged timely. According to informed sources, this kind of "charging" model is mainly focused on charging the batteries at night when the power is low, and then filling these batteries during the day. An electric power battery is distributed to each charging station. The low cost of charging at night can also reduce the fluctuation range of the power load of the grid and earn the difference. The user does not need to pay the battery charge, but only pays the electricity fee involved in charging.

Although the electric vehicle has been vigorously supported by the state as a strategic emerging industry, it suffers from a series of bottlenecks such as slow battery charging and large-scale construction of the charging station, and the development is slow.

"Upgrading a simple charging station to a battery-changing station that mainly replaces batteries and is supplemented by plug-in chargers is a choice for the State Grid to use its own strengths to avoid weaknesses and lay out the electric vehicle industry." said Li Shengmao, a senior researcher at China Investment Consulting Group. The station can provide two services for battery charging and battery replacement. In fact, it integrates vehicle purchase and battery leasing, two major domestic electric vehicle sales models, and increases the target customer group for charging and changing power stations, and enhances its geographical area. Adaptability.

In terms of development prospects, Zhang Lianlin, research director of China Investment Consulting, said that replacing battery-operated charge-and-replace power stations will make it possible to solve the problems of large current footprint, high cost, and inability to promote in large areas during the construction of current charging stations. Local government support.

Compared to energy researchers, auto industry experts are not so optimistic. Jia Xinguang, a senior commentator in the automotive industry, said: “Under the current technical conditions, it can only be said that this is a better attempt.” He believes that because different models of vehicles have different batteries, this model is for vehicle batteries. The unity is very dependent on it, so at present it is difficult to promote it nationwide and it can only be developed in cities. Because the battery life is not strong under the current technology conditions, it is difficult to find a battery that can be replaced when out of the city on long-distance driving. Therefore, this battery replacement mode is currently more suitable for urban taxis. Jia Xinguang believes that further promotion across the country still requires advances in battery technology and the replacement of power grid points.
