6 Frequently Asked Questions about “Discharge current of battery replacement”
How long does it take a battery to discharge?
The discharge current would have to be 30A to discharge the battery in 20 hours (600Ah / 20h). To work out the discharge time (the “C-rate”) from the Nominal Capacity and the Discharge current, divide the Nominal Capacity by the Discharge Current. This will give you the C-rate.
How do you calculate battery discharge current?
The discharge current can then be worked out from the C-rate and the Nominal Capacity. For example if a battery has a C1 capacity of 400Ah, this means that when the battery is discharged in 1 hour, it has a capacity of 400Ah. The discharge current would have to be 400A to discharge the battery in an hour.
How a battery discharge process is performed in safe conditions?
For the discharge process to be performed in safe conditions, besides gathering information about the battery's capacity, SoC and SoH at the beginning of the process it is necessary to monitor the temperature and voltage of individual modules, preferably even groups of cells, as well as to control the discharge current.
How many Ah can a battery discharge in 20 hours?
The discharge current would have to be 400A to discharge the battery in an hour. If the battery has a C20 capacity of 600Ah, it means that when the battery is discharged in 20 hours, it has a capacity of 600Ah. The discharge current would have to be 30A to discharge the battery in 20 hours (600Ah / 20h).
What is the current required for a 1 hour discharge?
A current required for a 1-hour discharge is described as 1C, a 2-hour discharge is C/2 or 0.5C and a 10-hour discharge is C/10 or 0.1C. The table below shows the discharge times for different C-rates. Discharging batteries with different C-rates will yield different capacity measurements.
How much does a high discharge current affect battery capacity?
With a higher discharge current, of say 40A, the capacity might fall to 400Ah. In other words, by increasing the discharge current by a factor of about 7, the overall capacity of the battery has fallen by 33%. It is very important to look at the capacity of the battery in Ah and the discharge current in A.
