Calculation method for battery capacity

• Clarify the load current

• Determine the discharge time of the battery

• Calculate the specific capacity of the battery according to below formula

Q:battery capacity（Ah）

K:Safety factor, taken as 1.25

I : Load current(A)

T:Discharge hours(h)

η:Discharge capacity coefficient

t:The minimum ambient temperature value of the actual battery location is considered to be 15 ℃ when there is heating equipment in the location, and 5 ℃ when there is no heating equipment;

α:Battery temperature coefficient (1/℃), when the discharge rate is ≥ 10, take α=0.006; When 1 ≤ discharge rate<10, take α=0.008; When the discharge rate is less than 1, take α=0.01
