The capacity of the battery is usually in ampere, hourly (referred to as AH, 1A.H = 36000c) battery capacity C calcoculator C = I∫T0TDT battery capacity is divided into actual capacity, theoretical capacity and rated capacity. The minimum capacity of the atmosphere of 25 ° C to the termination voltage is designed and produced by the predetermined battery, which is called an rated capacity of a certain discharge rate HR.
The battery capacity is typically calculated in AH (ampere hours), and the other is calculated as a Cell (unit plate) several watts (W). (W / cart)
1. AH (ampere hours) is calculated, defined in 20 hours. For example, a 7ah battery refers to a continuous discharge current of 0.35A, and time is 20 hours.
2.W (W (Will Power) / Cell (Unit Polater)) is calculated, defined in 15 minutes. For example, a 1221W battery is 12V (6 Cell), each Cell power supply 21W can supply for 15 minutes.
3. Charging time is based on 10 hours, charging current is 1/10 of battery capacity, and fast charging will reduce battery life. Battery capacity refers to the size of the battery storage capacity. The unit of battery capacity is "MAH", the Chinese name is mAh (when measuring a large-capacity battery such as a lead battery, generally use "AH", the Chinese name is safe, 1ah = 1000 mAh).
The capacity of the battery is related to the amount of discharge current and the temperature of the electrolyte, so the nominal capacity is between a certain discharge current, a certain termination voltage and a certain amount of electrolyte, there are two types. [3]
Rated Capacity
The rated capacity refers to the amount of power output to the monomer 1.75V in the case of a 20-hour current (1/20 of the rated capacity) that is discharged at a 20 hour rate (1/20 of the rated capacity) that is discharged (1/20 of the rated capacity) is discharged at an electrolyte. [3]
Start capacity
Normal temperature starting capacity: When the electrolytic solution temperature is 30 ° C, the output amount is continuously discharged to a predetermined termination voltage (6V battery is 4.5V, 12V battery is 9V) at a 5 min rate discharge current (3 times the rated capacity current). The discharge duration should be above 5 min
Low temperature starting capacity: When the electrolytic solution temperature is -18 ° C, the amount of electricity released at the time of 3 times rated capacity is continuously discharged to a predetermined termination voltage (12V battery is 6V, 6V battery is 3V), and the discharge duration should be in 2.5 MIN above.
