Embodiment
[0010] like figure 1 Shown, a kind of intelligent storage battery charging method, specifically:
[0011] A. According to the charging characteristics of the storage battery, the gas evolution potential is used as the basis for switching the charging mode, and the single-chip microprocessor 2 is used to set the charger to multiple charging modes. The establishment of the charging mode of the battery is based on the electrochemical charging characteristics of the battery. During charging, the charge receiving capacity of the battery should be improved as much as possible, and water loss should be reduced as much as possible. The initial capacity value is used to determine the initial charging current. When the battery capacity is low, high current charging can be used to improve the battery charge receiving capacity; when the battery capacity is high, low current charging can be used to achieve the best depolarization of the battery. Effect;
[0012] B. Judging the initial ca...

The invention belongs to the battery charge technique, in particular to an intelligent battery charge method characterized in that the charger is set into a plurality of charge modes by a single chip microprocessor using condensate gas potential as charge mode conversion basis according to the charge characteristic of battery, the initial capacity state of the battery is judged by a circuit composed of a voltage detection circuit, a current detection circuit, a battery charging circuit and the single chip microprocessor, wherein the high frequency switching power supply is used as the charge main circuit, the charge is selected according to the charge control mode set by the single chip microprocessor, the charging voltage and the charging current during the charging process is detected real timely and the high frequency switching power supply is closed-loop controlled. The intelligent battery charge method of the invention can set more than twenty types charge control modes, which not only ensures the battery to fully charge, but also reduces the plate salinization and water loss of the battery, guarantees the needed electron storage level for riding an electric motor car, prevents charge out of control of the battery and prolongs the battery service life.
Description
technical field [0001] The invention belongs to the technical field of storage battery charging. Background technique [0002] At present, electric bicycles generally use lead-acid batteries in series for charging, and the charger adopts a three-stage charging method of constant current, constant voltage and small current floating charge. According to the survey results of electric bicycle users, during the use of electric bicycles, most users do not ride long distances every day, and the batteries are not deeply discharged. If electric vehicle users use the existing three-stage charger to charge as they use it, long-term charging will cause battery plate salinization and water loss, shortening the service life of the battery pack; It is not scientific and reasonable to cause deformation and damage due to thermal runaway during charging. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art and provide a mo...
