Dare to introduce the depth of discharge of lithium-ion batteries

1. The discharge depth of the lithium ion battery is 80%, which means that it is discharged to the remaining 20% u200bu200bof the capacity. The effect of the depth of discharge on the battery is: the deeper the depth of discharge, the simpler the life of the lithium-ion battery will be shortened; the other aspect is the performance on the discharge curve. The deeper the discharge, the more unstable the voltage and current. Under the same discharge system, the smaller the voltage value, the deeper the discharge depth. Small current discharge is more complete. The smaller the current and the longer the working time, the less charged electricity will reach the same voltage. In short, any topic commenting on the discharge of lithium-ion batteries must consider the discharge system, the key is the current. 2. When a lithium-ion battery supplies a constant amount of current to any electrical appliance, the internal resistance of the battery will increase with the decrease in capacity. Then when the depth of discharge is large, the resistance increases and the current is constant, and the battery is required to supply more power. The heat is wasted in the form of heat. 3. The relatively stable discharge curve of lithium-ion batteries 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 of the power and also get Better use experience. Attention should be paid to the discharging process of lithium-ion batteries. In fact, the discharging of lithium-ion batteries is to figure out the factors that affect the discharge of lithium-ion batteries. It is important to perform related operations at the time of discharge, which is also conducive to 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 an intermediate state of power, in which case the battery life is the longest.
