Analysis on the operation mode of battery replacement for pure electric vehicles

First of all, the development of pure electric vehicles is the most prominent problem (1) The price of new vehicles is relatively high. Compared with cars of the same level, the price of pure electric vehicles is usually about one-third of its price, although the government has issued corresponding measures. The subsidy policy, but still because the cost is not high, affects the choice of new car owners. (2) The charging station is not perfect. The charging station's supporting facilities are not perfect, and the charging time is long, which greatly reduces the convenience of using pure electric vehicles and affects the enthusiasm of car owners to use pure electric vehicles. (3) Power lithium-ion battery technology is immature. Power lithium-ion battery technology is not yet mature and expensive. Although the current battery life is generally about 10 years, if there is a problem after the battery warranty period, it will bring great economic losses to the car owner; in addition, even after the battery life is over, the cost of replacing the power lithium-ion battery will also be Close to the price of mid-range cars, which is why owners of pure electric cars are reluctant to buy. The second is to solve the problem (1) Regarding the excessively high price of new cars, the following methods can be adopted to solve the problem. A new car owner buys an electric car, and the car owner pays the price of my car (not including battery charging), and forms a complete set of batteries. After forming a complete set of batteries, they should sign a lease contract and pay the cost of using the battery for the first time. A new car battery can be supplied. Ownership of the battery supplier of the battery, the owner shall not be transferred or artificially damaged, otherwise the corresponding compensation liability, in addition, the battery recycling, update is completed by the battery supplier. This not only reduces the down payment for car owners to purchase pure electric vehicles, but also standardizes the battery recycling process. (2) In view of the current situation of imperfect charging station facilities and long charging time, the following ideas can be adopted for improvement: 1. At present, under the conditions of charging station construction, not only a large-capacity power supply, but also a certain amount of space must be available . This is because the vehicle will occupy a parking space for charging. If the charging station is changed to a battery replacement service point, the time for the vehicle to stay at the station is shortened, and the charging station is only a room for charging the battery and a temporary parking space for the vehicle to replace the battery, which greatly reduces the requirements on the website and also supplies The conditions for construction and corresponding services are divided into cities or highways. 2. For the charging of pure electric vehicles, owners should be able to charge the battery itself theoretically, but in reality, most owners do not charge their own conditions, which is mainly affected by many factors such as heavy batteries and living buildings and community environment. In addition, even with slow charging, it can reach more than 3 kilowatts. Taking into account the carrying capacity of the civilian power grid, if pure electric vehicles are promoted, many car owners will conduct self-charging extensively, which will also have a certain impact on the civilian power grid. On the other hand, even if the owner is equipped with a charger when charging by himself (charging current is limited, it belongs to slow charging), the time is longer and the practicality is poor. Taking a pure electric vehicle as an example, the slow charging time will reach more than 10 hours, and the charging time for passenger cars or other large-capacity batteries will be longer; if fast charging is used, the time for the car to fully charge the battery is generally about half an hour, but this requires The power consumption of professional charging equipment is huge, and the single point is tens of kilowatts, which is simply unbearable by the civil power grid. Therefore, the charging service station is still regarded as an important charging service station. 3. If the charging gas station adopts the method of replacing the battery, the waiting time of the customer will change from the original charging time of more than half an hour to the battery replacement time of a few minutes, which greatly shortens the waiting time for the owner and saves the travel time for the owner. At the same time, the charging method of the battery in the charging station is not necessarily fast charging, but more efficient and reliable charging. A proper charging method can not only ensure the full charge of the battery, but also ensure the safety and life of the battery.
