Lithium battery discharge and protection.home solar battery system

　　Discharge

　　For the first time, if the time can be longer (usually 3--4 hours is sufficient), then the electrode can reach the maximum oxidation (sufficient power) as much as possible, and when the discharge (or use) The voltage, or until it is automatically shut down, can activate the battery capacity.

　　However, in the usual use of lithium ion batteries, there is no need to operate, and it can be charged as needed at any time. It is not necessary to be fully charged or discharged first when charging. The operation like the first charging and discharge requires only 1-2 times in a row every 3--4 months.

　　Internal short circuit protection

　　Lithium -ion batteries have risks of internal short circuits due to the influence of many aspects such as the material system and the processing process. Although lithium ion batteries have undergone strict aging and self -discharge screening when they leave the factory, due to the failure of the process and other unpredictable use factors, there is still a certain failure probability that causes internal short circuits during use. For power batteries, there are hundreds of lithium -ion batteries in the battery pack of hundreds or even tens of thousands of sections, which greatly enlarges the probability of internal shortcomings in the battery pack. Due to the great energy contained in the power battery pack, the internal short circuit occurs very easily to induce malignant accidents, resulting in casualties and property losses.
