Low temperature affects the function of lithium ion battery pack
▲ Low temperature affects the energy of the charging motor
Following the low temperature, the average voltage and discharge capacity of the lithium-ion battery have lowered, especially when the temperature is -20 ° C, the battery discharge capacity and the average voltage of discharge have dropped rapidly.
▲ Low temperature affects the reincarnation machine
The capacity attenuation at a capacity at -10 ° C is faster, with only 59mAh/g with a capacity after 100 times and 47.8%attenuation at the capacity. Essence Its capacity regulations re -recovered to 70.8mAh/g, with a capacity loss of 68%. It can be seen that the low -temperature reincarnation of batteries has a greater impact on the regulation of battery capacity.
▲ Low temperature affects peaceful machines
Lithium -ion battery charging is the process of lithium ion migration from the orthopedic removal of the electrolytic solution into the burden polar material. The lithium ion polymerizes the negative electrode, and a lithium ion is captured by six carbon atoms. At low temperature, the chemical response activity is low, and at the same time, the migration of lithium ions becomes slower. The lithium ion with the negative appearance has not yet been embedded in the negative electrode to be restored into metal lithium first, and the formation of lithium branch crystals in the negative electrode appearance. This is easy to pierce it. The barrier causes short circuits in the battery, and then damage the battery, causing peace and chaos.(Lithium - Ion Battery Equipment)
The lithium -ion battery pack is best not to charge in winter. Due to the low temperature, the lithium ion nesting on the negative electrode will show ion crystals, directly piercing the gap, and the general environment will cause a short circuit to affect life and function, and serious direct explosion. Therefore, some people responded that the charging of lithium ion batteries in winter could not be charged, because the department brought the battery to the dot system because the product was covered by the product.
