There are requirements for battery charging temperature -Lithium - Ion Battery Equipment
At the time of charging the lithium -ion battery, does the battery charging and discharge be required for the temperature? Charging the lithium -ion battery should control the charging current and charging voltage in the order of the time order, and it cannot be charged, otherwise it will easily damage the battery. The battery has a harsh requirements for the charging and discharge environment. The best charging environment of the battery is 5 ~ 45 ° C. Although it can still be charged normally at 0 ~ 5 ° C, the charging current must be reduced by 5 ~ 45 ° C. Essence
The time of lithium ion battery charging
1. Calculation of lithium -ion battery charging time
1. The calculation formula is as follows: charging time T = battery power C/charging current i
2. View your lithium -ion battery capacity: The nominal capacity indicated on the label, assuming that your lithium ion battery capacity is 2200mAh.
3. The output current of the charger you use depends on the output current of your charger: The labeling of the output voltage current of the charger is generally: DC ×× V ×× MA, assuming that the target on your charger is 1100mAh.
4. Charging time T = battery power C/charging current i = 2200mAh/1100mAh = 2 hours
5. This is just the time for the battery to be charging. The lithium -ion battery uses the charging mode of the constant current and the constant voltage, so the charging time will be added for about 1 hour, that is, the total charging time is 3 hours.
2. How long is the charging of lithium -ion batteries charging
1. The currently popular lithium battery charger is full of self -stop, and there is no need to worry about charging without ‘overcharge’ reassuring;
2. There is no memory effect in the lithium battery, so it does not affect the battery at any time;
3. It is recommended to charge 30%of the balance, which is beneficial to the life of lithium -ion battery.
Is the battery charging and discharge requirements for temperature?
Among all environmental factors, temperature has the greatest effect on the charging and discharge performance of the battery. The electrochemical reactions on the electrode/electrolyte interface are related to the ambient temperature. The electrode/electrolyte interface is considered the heart of the battery. If the temperature decreases, the reaction rate of the electrode also decreases. Assuming that the battery voltage is kept constant, the discharge current is reduced, and the power output of the battery will decrease.(Lithium - Ion Battery Equipment)
If the temperature rises, the opposite is the opposite, that is, the battery output power will rise, the temperature will also affect the temperature of the transmission speed of the electrolyte, the temperature will increase, the transmission temperature decreases, the transmission is slowed, and the battery filling and discharge performance will be affected. However, the temperature is too high, exceeding 45 ° C, which will destroy the chemical balance in the battery and lead to a side effect.
Many companies' battery products can achieve normal discharge at low temperatures, but at the same temperature, it is more difficult to achieve normal charging, and it cannot even charge. When li+embedded graphite materials, the solvent must be removed first. This process will consume certain energy. It hinders li+spread to the inside of the graphite;
Instead, when the graphite material is removed into the solution, there will be a solvent -based process, and the solvent does not consume energy. Li+can quickly remove the graphite. Therefore, the charging ability of graphite materials is obviously inferior to discharge acceptance capabilities.
Frozen lead -acid batteries can cause permanent damage. Always keep the battery charging, because in the state of discharge, the electrolyte becomes more like water, which is easier to freeze than full power. The immersed lead -acid batteries often rupture. If it is frozen, it will cause leaks; the sealing lead -acid packaging is lost, and it can only be supplied to several charging cycles before failure.
Lithium -ion batteries can supply quite good charging performance at a cold temperature, and can quickly charge within the temperature range of +5 to+45OC. When it is lower than+5OC, the charging current should be reduced, and charging is not allowed at the freezing temperature. During the charging process, the internal battery core resistance causes a slight temperature to increase, thereby compensating some cold. The internal resistance of all batteries becomes higher when cold.
