How long is the service life of lithium battery electric vehicles and lead-acid batteries?

The life of a lead-acid battery is defined as the battery capacity decays to 30% of the original capacity. Generally, it should be fully charged and discharged for about 300 times, and the lifespan is about one and a half years. If the riding distance is short, it can be used for about 3 years; a normal car The battery used on it is a lead-acid battery. The capacity and discharge capacity of car batteries will decrease after being used for more than 2 years. The life of the general car battery will not exceed 4 years. Of course, a well-maintained battery will last longer. Lithium batteries have a strict number of recharges, usually around 1000-1200 times, with a life span of 3-5 years. However, the charging of lithium batteries is the opposite of that of lead-acid batteries. They must be recharged after being used up. When the battery is not used for a long time, it needs to be fully charged once every two months, which can extend the battery life. Lithium batteries used in electric vehicles have a longer life than lead-acid batteries. Lithium batteries store more power than lead-acid batteries, and the power they exert is also very powerful. There are also lithium batteries that have the ability to protect themselves after being fully charged, that is, they can’t be recharged after being fully charged. . But the lead-acid battery is completely different. After it is fully charged, although the charger shows that it is full and the green light is on, outsiders seem to think that the charger has stopped working, and it is still charging slowly for a small amount of time. If it takes a long time to charge , Then the lead-acid battery is the easiest to charge and explode, and the battery is scrapped. Lead-acid batteries: batteries are widely used and widely studied by various electric vehicles in various countries due to their low price, abundant material sources, high specific power, mature technology and manufacturing process, and high resource recovery rate. Electric bicycles have been widely accepted by people as a labor-saving, convenient, fast, comfortable, low-cost, and zero-emission personal transportation tool, and have been valued by relevant national departments. Lithium batteries: Lithium batteries are generally considered to have the following advantages: large specific energy; high specific power; low self-discharge; no memory effect; good cycle characteristics; fast discharge and high efficiency; wide operating temperature range; no environmental pollution, etc. . When lithium batteries develop further, the market share of MH/Ni batteries will shrink. Lithium-ion market share will expand.
