Why will the winter electric car battery use time be shorter?

For lithium-ion batteries, there is currently no clear theory that has no clear theory to support its temperature performance, discharge platform, life, capacity, etc., related calculation formulas and mathematical models are still exploiting. In general, the temperature of the lithium ion battery is not sensitive to the temperature of 0-40 ¡ã C, however, once the temperature exceeds this, life and capacity will be discounted.

Detailed non-quantitative presentation is not a way, because the lithium ion battery activity is too high, the consistency is also the biggest problem, even if the same batch, the same material, the same type of processes, the performance will also have a big difference. After making a lot of trials, the low temperature performance of the lithium-ion battery of different materials is also different. Today's hottest lithium iron phosphate is the worst, our products are in the maximum capacity of 89% of the maximum capacity at -10 ¡ã C, should be in the industry It is already relatively high; the release capacity at 55 ¡ã C can reach 95%, relatively low temperature attenuation is still relatively small.

This is still a product, everyone understands, quality relative to the normal product is much higher. Relatively speaking, lithium manganate, lithium cobaltate and low temperature performance of the ternary product are better, but it is limited; while sacrificing high temperature performance. This industry is high in the industry, the phosphate is high, and the high temperature performance is good.

In fact, there is no three high-mentioned high, relatively safe. Overall performance is still as good as manganese or ternary. Therefore, some people reflect the charging of the lithium-ion battery charge in winter, and some of the battery management system is due to the protection of the product, and there is still because of the quality problems.

Lithium-ion battery is inevitably used in winter than summer. I will remind everyone that the lithium-ion battery is best not to charge in winter. Due to the low temperature, nesting lithium ions on the negative electrode will have ion crystals, straight piercing diaphragms, in general, cause micro-short roads affect life and performance, and severe possible explosi.
