Battery C Rating Chart
A 1C rating means the battery discharges fully in one hour. A 2C rating indicates a 30-minute discharge, while 0.5C represents a two
For example, a 1C rate means charging or discharging the battery to its full capacity in one hour, regardless of its capacity. For a battery with a capacity of 45Ah, a 1C rate equates to a discharge current of 45A; for a 10Ah battery, discharging at 1C rate means a discharge current of 10A. In both cases, the discharge time are the same, one hour.
For a battery with a capacity of 45Ah, a 1C rate equates to a discharge current of 45A; for a 10Ah battery, discharging at 1C rate means a discharge current of 10A. In both cases, the discharge time are the same, one hour. 1. Battery Capacity: The C-rate is closely related to battery capacity.
1C rate → The battery charges/discharges in 1 hour. 2C rate → The battery charges/discharges in 0.5 hours. 0.5C rate → The battery charges/discharges in 2 hours. Example: If a battery has a capacity of 10Ah: At 1C, the current = 10A → Fully discharged in 1 hour. At 2C, the current = 20A → Fully discharged in 0.5 hours.
The charging and discharging speed of a BESS is denoted by its C-rate, which relates the current to the battery's capacity. The C-rate is a critical factor influencing how quickly a battery can be charged or discharged without compromising its performance or lifespan.
