The depth of discharge of lithium-ion batteries, the factors that limit the depth of discharge of lithium-ion batteries. Since the lithium-ion battery is charged, there must be discharge. In theory, the discharge process of the lithium-ion battery is balanced. When discharging, pay attention to the discharge rate and the depth of discharge. The depth of discharge is the ratio of the discharge amount to the nominal capacity. The best reference target voltage available. The depth of discharge of a lithium-ion battery refers to the ratio of the discharged capacity of the lithium-ion battery to the total stored capacity (nominal capacity). A lower number means a shallower discharge. The depth of discharge of lithium-ion batteries is closely related to voltage and current. It can be said that it is expressed in voltage and used in current.

1. The depth of discharge of the lithium-ion battery is 80%, which means that it is discharged to the remaining 20% of the capacity. The impact of the depth of discharge on the battery is: the deeper the depth of discharge, the simpler the life of the lithium-ion battery is shortened; the other aspect is the performance on the discharge curve, the deeper the discharge goes, the more unstable the voltage and current are. Under the same discharge regime, the smaller the voltage value, the deeper the discharge depth. Small current discharge is more complete, the smaller the current, the longer the working time, the less the charged amount at the same voltage. In conclusion, any topic commenting on lithium-ion battery discharge should consider the discharge regime, the key being the current.

2. When the lithium-ion battery supplies current to any electrical appliance quantitatively, the internal resistance of the battery will increase with the decrease of the capacity. When the depth of discharge is large, the resistance increases and the current is constant, which requires the battery to supply more power, and use wasted in the form of heat.

3. Lithium-ion batteries are originally relatively stable and the discharge curve will change sharply when the depth of discharge is large. Therefore, limiting the depth of discharge to a relatively flat range can enable customers to have a better control over the power, and also get Better use experience.

In the process of lithium-ion battery discharge, attention needs to be paid to the problem. Li-ion battery discharge is actually to find out the factors that affect lithium-ion battery discharge. It is important to do relevant operations at the discharge time, which is also conducive to the longer-lasting use of the battery. .

The deeper the discharge depth of the lithium-ion battery, the greater the loss of the battery; the more fully charged the lithium-ion battery, the greater the loss of the battery. Lithium-ion batteries are best in the middle state of charge, so the battery life is the longest.
