6 FAQs about [Battery constant voltage discharge current change]

What is a constant current discharge of a lithium ion battery?

What happens if a CC discharge is less than a battery voltage?

If you use constant voltage less than the battery voltage the only thing limiting the current is the battery resistance. That, being small, means the initial current is very high and uncontrolled. This will result in overheating and potential fire/explosion. The whole point of CC discharge is to limit that heating effect. Thank you.

What happens if a battery is discharged constant power?

Keep the discharge power unchanged, because the voltage of the battery continues to drop during the discharge process, so the current in the constant power discharge continues to rise. Due to the constant power discharge, the time coordinate axis is easily converted into the energy (the product of power and time) coordinate axis.

What affects the change of battery discharge voltage?

The change of the battery discharge voltage is related to the discharge system, that is, the change of the discharge curve is also affected by the discharge system, including: discharge current, discharge temperature, discharge termination voltage; intermittent or continuous discharge.

How does a battery discharge?

The nature of the load (constant current, constant power, or variable load) affects how the battery discharges. Constant power loads, for example, will lead to a different voltage drop pattern compared to constant current loads. 8. Internal Impedance:

What is constant voltage mode (CV mode) in EV charging?
