Calculation formula of battery capacity

Q≥KIT/η[1+α（t-25）]

Where: Q -- battery capacity (ah);

K -- safety factor, taking 1.25;

I -- load current (a);

T -- discharge hours (H);

η - discharge capacity coefficient;

T - Minimum ambient temperature value of the actual battery location (Guangdong is considered as 5 ℃)

α - cell temperature coefficient (1 / ℃),

When the discharge hourly rate is ≥ 10, α = 0.006;

When 10 > discharge hour rate ≥ 1, α = 0.008;

When the discharge hourly rate is less than 1, α = 0.01;
