Embodiment 1
[0045] Taking a 12V battery and a 10A charger as an example, the full voltage of the 12V battery is 14.6V. For the multi-stage intelligent charging method for aging batteries, please refer to figure 1 The charging curve diagram includes the following steps:
[0046] (1) Diagnose, detect the battery voltage, and judge the next action of the charger;
[0047] (2) Pulse desulfurization, using pulse current and voltage to remove sulfide on the battery plate and restore battery capacity;
[0048] (3) Pre-charge, when the battery voltage is lower than 12V, in order to protect the battery, charge the battery with a small current until the battery voltage reaches a safe value;
[0049] (4) Soft start, the charging current rises slowly from small to large, preventing the sudden change of charging current from impacting the battery and protecting the battery;
[0050] (5) Constant current one, charge the battery with current I1 until the battery voltage reaches 13.6V;
[0051] (6) C...
Embodiment 2
[0066] Taking a 12V battery and a 10A charger as an example, the full voltage of the 12V battery is 14.6V. For the multi-stage intelligent charging method for normal batteries, please refer to image 3 The charging curve diagram includes the following steps:
[0067] (1) Diagnose, detect the battery voltage, and judge the next action of the charger;
[0068] (2) Soft start, the charging current rises slowly from small to large, preventing the sudden change of charging current from impacting the battery and protecting the battery;
[0069] (3) Constant current one, charge the battery with current I1 until the battery voltage reaches 13.6V;
[0070] (4) Constant current 2, charge the battery with current I2 until the battery voltage reaches 14V;
[0071] (5) Constant current three, charge the battery with current I3 until the battery voltage reaches the full voltage of 14.6V;
[0072] (6) Constant voltage, the battery voltage remains unchanged, slowly reduce the charging cur...
Embodiment 3
[0078] Taking a 12V battery and a 10A charger as an example, the full voltage of the 12V battery is 14.6V. For the multi-stage intelligent charging method for normal low-voltage batteries, please refer to Figure 4 The charging curve diagram includes the following steps:
[0079] (1) Diagnose, detect the battery voltage, and judge the next action of the charger;
[0080] (2) Pre-charging, when the battery voltage is lower than 12V, in order to protect the battery, charge the battery with a small current until the battery voltage reaches a safe value;
[0081] (3) Soft start, the charging current rises slowly from small to large, preventing the sudden change of charging current from impacting the battery and protecting the battery;
[0082] (4) Constant current one, charge the battery with current I1 until the battery voltage reaches 13.6V;
[0083] (5) Constant current 2, charge the battery with current I2 until the battery voltage reaches 14V;
[0084] (6) Constant curren...
