Discharge capacity of lithium battery pack

How long can a battery be discharged?

Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.

What happens if lithium ion battery discharge current increases?

When the discharge current of a lithium ion battery increases, the released capacity and the released energy decrease significantly. In the discharge of lithium ion batteries, the national standard 1C is generally selected, and the maximum discharge current is usually limited to 2 ~ 3C.

What is a maximum continuous discharge current?

Maximum Continuous Discharge Current – The maximum current at which the battery can be discharged continuously. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.

What happens if you discharge a battery in one hour?

Generally, for a given capacity you will have less energy if you discharge in one hour than if you discharge in 20 hours, reversely you will store less energy in a battery with a current charge of 100 A during 1 h than with a current charge of 10 A during 10 h. This phenomenon is significant for Lead batteries, much less for lithium batteries.

What are the advantages of lithium ion batteries?

Lithium ion batteries have several advantages when it comes to discharge capacity: large capacity and high specific energy. These advantages have contributed to the rapid development of lithium batteries. Capacity, as the most critical performance index, has attracted much attention.

What is the capacity of a battery or accumulator?

The capacity of a battery or accumulator is the amount of energy stored according to specific temperature, charge and discharge current value and time of charge or discharge.
