6 FAQs about [Lithium battery maximum pulse discharge current]
What is the maximum current a battery can discharge?
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.
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 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 is a high discharge rate for a lithium ion battery?
Higher discharge rate lowers battery capacity significantly. A single cell, protected, lithium ion battery provides 1.4 A of current 1.4 A discharge rate for Li-ion is not excessive. It is about a 0.5C discharge for a typical 18650 Li-ion cell. There are different types of LI-ion with different discharge rates.
How much current does a lithium ion battery provide?
A single cell, protected, lithium ion battery provides 1.4 A of current 1.4 A discharge rate for Li-ion is not excessive. It is about a 0.5C discharge for a typical 18650 Li-ion cell. There are different types of LI-ion with different discharge rates. LCO Li-ion should not be discharged at a rate greater than it capacity.
Do high discharge rates reduce battery capacity?
Lithium-ion and NiCad batteries have a low Peukart effect, and so high discharge rates don't reduce the capacity very much. But an intermediate case is of great interest. What would happen if you discharged a battery in high-current pulses spaced far apart?
