How Is C Rating Calculated for Batteries?
C rating is calculated for batteries by determining the charge and discharge rates relative to the battery’s capacity. To calculate the C rating, follow these steps:
-
Identify the battery’s capacity in ampere-hours (Ah). For example, a battery rated at 200 Ah has a specific capacity.
-
Determine the desired discharge or charge current in amperes (A). For instance, if the battery discharges at 100 A, this value will be used.
-
Divide the current by the capacity. This calculation gives the C rating. For the example of a 200 Ah battery discharging at 100 A, divide 100 A by 200 Ah. The calculation yields a C rating of 0.5C.
-
Interpret the C rating. A C rating of 1C means the battery can be charged or discharged at a current equal to its capacity. A rating less than 1C indicates lower charge or discharge rates, while a rating higher than 1C indicates higher rates.
In summary, use the battery capacity and the current to find the C rating. This rating indicates the charge and discharge capabilities of the battery, affecting its performance during use.
