Embodiment 1
[0053] A battery charging method such as figure 1 shown, including the following steps:
[0054] S1: The system is powered on and reads the SOC value in the computer storage medium to perform the charging state;
[0055] S2: dividing the SOC value into intervals including a low battery SOC interval and a high battery SOC interval;
[0056] S3: Read the range of the SOC value, and judge whether the SOC value is in the low range of the battery SOC, if so, use small current constant current charging, otherwise execute S4;
[0057] S4: Determine whether the SOC value has entered the high SOC range of the battery, if not, use high-rate constant current charging, otherwise execute S5;
[0059]S6: Determine whether the pulse current is greater than the minimum current, if so, use the pulse current to charge, otherwise use the minimum current to charge.
Embodiment 2
[0061] Such as Figure 2-6 Shown, a kind of battery charging method comprises the following steps:
[0062] S1: Power on the system and read the SOC value in the computer storage medium to check the charging state.
[0063] Wherein, S1 specifically includes the following steps:
[0065] S12: read the SOC value in the computer storage medium;
[0066] S13: continue to judge whether it is in the charging state, if so, enter S14, otherwise return to S12;
[0067] S14: Divide the SOC value range into a low battery SOC range and a high battery SOC range.
[0068] S2: dividing the SOC value into intervals including a low battery SOC interval and a high battery SOC interval;
[0069] The low range of SOC is battery SOC<10%;
[0070] The range of the battery SOC high range is battery SOC>90%.
[0071] S3: Read the range of the SOC value, and judge whether the SOC value is in the low range of the battery SOC, if so, use small current constant c...

Abstract
The invention discloses a battery charging method and a computer readable storage medium. The problems that in the prior art, charging time is long, and the overcharging prevention function cannot beconsidered at the same time are solved. Pulse current is adopted for charging in a high residual electric quantity interval of the battery; the adopted charging mode is judged by judging the SOC valueof the battery; the charging mode comprises low-current charging and high-rate constant-current charging. The pulse current is judged to select between the minimum current charging mode and the pulsecurrent charging mode only when the residual electric quantity of the battery is in the SOC high interval; therefore, the charging polarization voltage of the battery cell is reduced, the output difficulty of the charger is reduced by adopting a stepped rectangular group equivalent index curve, the maximum approximate maximum charging current is ensured for charging, charging time is reduced, andthe purpose of rapid charging is achieved.
Description
technical field [0001] The invention relates to the technical field of battery management, in particular to a battery charging method and a computer-readable storage medium for reducing charging time and damage to the battery during charging. Background technique [0002] As the market has higher and higher requirements for new energy vehicles, energy storage, and 3C electronic products, the charging speed of batteries has attracted much attention. Appropriate charging method can reduce the charging time, prevent the battery from overcharging, and reduce the damage to the battery caused by charging. [0003] At present, the main charging method is CC (Constant Current, constant current)-CV (Constant Voltage, constant voltage) charging method. When the remaining battery power is in the low range, CC charging is used. By increasing the charging current, the charging time is shortened. When the remaining battery power reaches the high range, the CV method is used to charge, an...
