Embodiment Construction
[0041] Such as figure 1 Shown, a kind of lead-acid storage battery charging method comprises:
[0042] Step 1: Select a charging mode, which includes normal charging mode, emergency charging mode and maintenance charging mode;
[0043] Step 2: Charging, charge the battery according to the charging steps in the selected charging mode;
[0044] In the normal charging mode, the charging method includes the following steps:
[0045] Step 1: Charge with a constant current of 0.05C for 2 minutes;
[0046] Step 2: Judging whether the battery voltage has risen to 98% of the rated voltage, if the result is yes, go to step 11, otherwise go to the next step;
[0047] Step 3: Charge with a constant current of 0.3C for 2 minutes;
[0048] Step 4: Determine whether the battery voltage has risen to 90% of the rated voltage, if the result is yes, go to step 6, otherwise go to the next step;
[0049] Step 5: Perform pulse charging until the battery voltage reaches 90% of the rated voltage...
