Problems solved by technology
However, the constant voltage charging method brings four problems: first, the charging current decreases with the rise of the battery voltage, and the charging time is long; second, due to the influence of the sampling feedback resistor, the charging voltage has a certain error, which makes the charging effect of the product The consistency is poor; third, when the charger is over-discharged, the battery cannot be fully charged and cannot meet the requirements of the service time, and when the charging voltage of the battery is too high, there will be overcharging and there is a hidden danger of accidents; fourth, the battery will be over-discharged. Cause battery performance to degrade Constant voltage charging will damage the battery
And it has a great influence on the service life of Ni-MH batteries.

The present invention discloses a nickel-hydrogen battery charging equipment, which comprises a micro-processing unit and a charging unit. Wherein, the micro-processing unit is composed of a battery voltage sampling module and a charging control module. The charging control module controls the charging unit according to voltage information collected by the battery voltage sampling module. The charging unit is composed of a constant current control circuit, a constant voltage control circuit and a trickle control circuit connected in parallel, a charging circuit and a charging mode control circuit. The charging mode control circuit controls the constant current control circuit, the constant voltage control circuit and the tickle control circuit to select constant current, constant voltage and trickle charging mode according to a control signal of the charging control module. Based on the charging circuit, the nickel-hydrogen battery is charged. The present invention also discloses a nickel-hydrogen battery charging method and a terminal applying the charging equipment and the method above.
Description
technical field [0001] The invention relates to a charging device, in particular to a charging device and method for a nickel-metal hydride battery and a terminal using the charging device and method. Background technique [0002] Most of the charging devices in the prior art adopt a constant voltage charging method for charging the Ni-MH battery. However, the constant voltage charging method brings four problems: first, the charging current decreases with the rise of the battery voltage, and the charging time is long; second, due to the influence of the sampling feedback resistor, the charging voltage has a certain error, which makes the charging effect of the product The consistency is poor; third, when the charger is over-discharged, the battery cannot be fully charged and cannot meet the requirements of the service time, and when the charging voltage of the battery is too high, there will be overcharging and there is a hidden danger of accidents; fourth, the battery will...
