FAQs about Battery constant power test

How do you test a battery?

There are several methods: constant current discharge, constant power discharge, constant resistance discharge that can be used to perform a capacity test, but the most common method involves discharging the battery at a constant current until the voltage drops to a predetermined level.

What is a constant current method for a battery performance test?

For the performance test, a constant current method is generally used where a constant current specified by the manufacturer is applied for an accompanying specified time. Battery manufacturers publish tables that include different discharge rates specified for different periods of time.

Why is constant power discharge test important?

Because this determines the ability of the battery system to stabilize the output power, which in turn affects the vehicle performance of the EV. The following table is the main test steps for the constant power discharge test of battery cells at different temperatures and different powers.

How does a battery test work?

Within the power test, the cell was discharged with a constant power regime, until 0.00 V cell voltage was reached. Current and voltage were controlled by the battery tester so a constant discharge power was observed. To avoid heating up the cell during the experiment, another temperature equilibrium phase of 1 hour was set.

What is a battery performance test?

A performance test is defined as “a constant-current or constant-power capacity test made on a battery after it has been in service”2.
