Car Battery Current Value

The positive and negative poles of the car battery are directly connected. Short-circuit current: The current that flows immediately after the battery is short-circuited. Discharge rate: Discharge rate refers to the rate of discharge, commonly used "time rate" and "multiplying rate". Time rate refers to the discharge rate expressed by the discharge time (h), that is, the number of hours required to discharge the rated capacity with a certain discharge current. For example, if the rated capacity of a car battery is 30 Ah and it is discharged at a current of 2 A, the time rate is 30 Ah/2 A = 15 h, and the battery is said to be discharged at a rate of 15 hours.

The rate refers to the current value output by the battery when it discharges its rated capacity within a specified time, and the value is equal to a multiple of the rated capacity. For example, a double-rate discharge indicates that the discharge current value is twice the battery capacity. If the battery capacity is 3 Ah, then the discharge current should be 2x3 2 6 Ao. If you convert the 2 times discharge into an hour rate, it is 3 Ah/6 A = 1/2 hour rate. Time rate and magnification are reciprocal in value. Depth of discharge DOD (depth of discharge): The percentage of discharge capacity and rated capacity. Active material: The electrode material that can generate electric energy through oxidation or reduction reaction when the battery is discharged.
