A few years electric lithium battery can normal use?

Source: 2020 - 03 - 24 17:06 hits: how long time electric car lithium-ion battery life: an electric car lithium-ion batteries can use how long? Believe that the vast majority of customers hear, lithium battery life is' 500 times, 500 times, beyond the Numbers, the battery is' death ', a lot of friends in order to extend battery life, every time before charging battery completely exhausted, the battery life is really extension effect? The answer is no. The life of the lithium ion battery is' 500 ', not the number of charging, but a charge and discharge cycle. Refers to the capacity of the battery charging cycle from full to empty, and then from empty to full, this is different from charge. Lithium-ion batteries used in the first day, for example, half of the electricity, then slowly recharge. If the day is the same, you can fill in half, and then charged twice, it's a cycle, not two. Therefore, it is usually need a few charge to complete a cycle. Every cycle, the battery capacity will reduce a little. However, lower amplitude is small, high quality batteries in many times after charging still can maintain 80% of the original capacity, many lithium-ion products are still in use after two or three years. Of course, after the lithium battery service life, still need to be replaced. The so-called 500 charges, is refers to the manufacturer under the stable discharge depth around 625 times the number of rechargeable, charging cycle of up to 500 times. Due to various effects in real life, especially when charging discharge depth is not stable, so '500 times charging cycles can only be used as a reference battery life. Myth: we often have a 'after rechargeable lithium battery runs out' or 'lithium battery is full of continue to charge, have to be 12 hours' myths. Imagine, if you make a lithium-ion battery overcharge or overdischarge, not only can't make electric lithium battery life extension, but also can shorten. Battery to choose tips: 1. Don't ever buy lower than the market average wholesale price of the battery. 2. To inspect the products more than 2 years without market. 3, no electric car manufacturers resolute don't buy a car with a car battery. Four, high price of batteries, if not big manufacturers, determined not to buy. 5, replacement of national standard calibration cell determined not to buy it. 6, 5 a discharge, 30 seconds when the voltage is higher than 12. 68 v determined not to buy, more than 90% is short-lived batteries.
