50 sections in total. Take Shengte's 36V, 10.4A lithium battery as an example. The battery is composed of 5*5 double layer 18650 batteries (50 cells in total) has a capacity of approximately 2100 mAh. Wuyi Shengte Bicycle Co., Ltd. was created in 2010 and has been in development for 12 years. The main business of our company is electric scooters, electric bicycles and export business, which are sold at home and abroad.
First of all, the average lifespan of a battery is around seven or eight years. Nowadays, most batteries are recyclable, like those in electric bikes on the market today. Once the battery life expires, it can be replaced with a new one and then refurbished. The same goes for new energy vehicle batteries. The editor checked the information and learned that many new energy vehicle manufacturers pcan now provide warranty, replacement and other battery services for a certain period! It is estimated that the popularity of new energy vehicles and the further development of battery technology will naturally reduce the price of batteries.
Second, replacingthe main batteryrequires between 50,000 and 1,000,000. Because the state subsidies for new energy vehicles directly subsidize the vehicle as a whole, not the battery. So, if users want to replace the battery, they have to pay the original price. The state requires that key parts of new energy vehicles be guaranteed for 5 years or 100,000 kilometers. During the warranty period, it is completely free for car owners. In order to reduce consumers' purchasing fears, many new energy vehicle brands offer equaladditional warranty services for batteries outside of the vehicle's normal warranty period.
In addition, the quality of a battery cannot be determined solely by its lifespan. Energy density, low temperatures, safety, etc. are all factors to take into account. Long-term high current charging and discharging will shorten the battery life, and the capacity will also decrease during battery storage. This requires that when using pure electric vehicles, use fast charging as little as possible; If the pure electric vehicle is parked for a long time, try to keep it fully charged to avoid long-term exposure of the battery. Although many manufacturers have implemented corresponding battery warranty services, once the warranty period ends, the battery deteriorates and if it needs to be replaced, theowner of the car must bear the costs. ?
You should know that electric batteries used in cars are roughly divided intolead-acid batteries, lithium batteries and nickel-metal hydride batteries. Among them, nickel-metal hydride batteries are only used in Toyota vehicles and are not suitable as a separate power source; lead-acid batteries are mainly used in low-speed electric vehicles, also called old-fashioned scooters; Lithium batteries are the most widely used energy source for electric vehicles. Batteries are divided into several types based on different materials. The more mature ones are mainly divided into ternary lithium batteries and lithium iron phosphate batteries.
