In electricity, the discharge rate is usually expressed in the following 2 ways. (1) Time rate: It is the discharge rate expressed in terms of discharge time, i.e. the time experienced by a certain current discharge to the specified termination voltage ch as C/5, C/10, C/20 (2) C rate: the ratio of the battery discharge current relative to the rated capacity, that is, times the rate.

I have been trying to figure out how to calculate the test current (It) for BEV application, the cell has a 6000mAh capacity. What would be the reference test current and the formula for it? Also, the charge current in the battery datasheet is 0.5 C, how would this work? The attached photo is of the test standard I have to apply.
IEEE Standards for testing and determining battery capacity such as IEEE Std 450 for VLA (Vented Lead-Acid), IEEE Std 1188 for VRLA (Valve Regulated Lead -Acid) and IEEE Std
For battery electrodes, measured capacity decays as charge/discharge current is increased. Such rate-performance is usually characterised via galvanostatic charge-discharge measurements, experiments which are very slow, limiting the speed at which rate experiments can be completed. This is particularly limiting during mechanistic studies where
