About the pure electric vehicle replacement battery operation mode analysis

Source: 2020 - 04 - 10 19:53 hits: first of all, the development of pure electric vehicles is one of the most prominent problem ( 1) New car prices are relatively high compared with the same level of the car, the price of pure electric vehicles is usually about a third of the price, although the government introduced the corresponding subsidy policy, but because the cost is not high, still affect the choice of the new car owners. ( 2) Imperfect charging charging facilities is not perfect, charging time is long, greatly reduce the pure electric vehicles use convenience, influence the enthusiasm of the owners use pure electric cars. ( 3) Power battery technology is not mature power battery technology is still immature, and expensive. Although the battery life is in commonly 10 years or so, but if the problems after the warranty period, the battery can bring great economic losses to the owner; In addition, even if at the end of the battery life, change the cost of power battery is close to a mid-range car prices, that is why the cause of the pure electric vehicle owners are reluctant to buy. The second is to solve the problem, A) For the new car price is too high, can take the following ways to solve. The new owners to buy electric cars, car owners prices (for my car Not including the battery) , and form a complete set of battery should be signed after the lease contract, and pay the cost of the battery for the first time, can provide a new car battery, the battery of battery supplier ownership, the owner shall not be transferred or artificial damage, otherwise the corresponding liability to pay compensation, in addition, the battery recycling, update performed by battery supplier. This not only reduced the owner a down payment on the purchase of pure electric cars, and standardizes the battery recycling. ( 2) According to current situation of incomplete charging station facilities, charging time long, you can take the following ideas for improvement: 1. At present, under the condition of the construction of the charging station, not only has a large capacity of power supply, but also to have certain space. This is because the vehicle charging take up parking Spaces. If a battery charging station to replace service point, time to stay in the station of the vehicle is shortened, and the place is only for the battery charging station room, and temporary parking vehicle replacement battery, this greatly reduces the requirements on the site, and also provides the conditions for urban construction and the corresponding service points or beside the highway. 2. Pure electric vehicle charging, the owner should be able to charge the battery itself in theory, but in reality, most of the owners did not charge her condition, it is mainly affected by many factors such as heavy batteries and living building and community environment. In addition, even with slow charging ways, also can achieve more than 3 kw. Considering the bearing capacity of the civil power grid, if pure electric vehicles, many owners to charge, will produce certain effect to civil power grid. On the other hand, even if the master himself when charging with the charger ( Charging current limiting, belongs to the slow charge) , its for a long time, poor practicability. Pure electric cars, for example, slow charging time can reach more than 10 hours, passenger cars or other large capacity battery, charging time will be longer; If use quick charge, car full of battery time in half an hour or so commonly, but it need professional charging equipment, power consumption is huge, single point is tens of kilowatts, civil power grid simply cannot afford. Therefore, charging stations is still considered the main charging stations. 3. If charging station adopt the method of replacement battery, customer waiting time will be taken from the original charge time more than half an hour of battery replacement time for a few minutes, greatly shorten the waiting time of the owner of the owner and save travel time. At the same time, the charging station in the battery charge mode is not necessarily the quick charge, but more efficient and reliable recharge. Proper charging ways can not only ensure the battery fully charged, and can guarantee the safety and life of the battery.
