Abstract

The invention relates to the fields of a charging management circuit and a power management circuit of a storage battery, in particular to a charging management circuit of a lead-acid storage battery. In the invention, a charging optimization manager is serially connected between a charger and a lead-acid storage battery pack; and the charging optimization manager monitors and acquires the terminal voltage signal of the lead-acid storage battery pack and the charging current signal of the charging circuit by means of a controller, controls an extra voltage to be superposed onto the charging circuit in a PWM (pulse width modulation) mode or turns on or turns off the charging circuit superposed with the extra voltage. The charging optimization manager of the lead-acid storage battery has simple structure, is used conveniently and is serially connected between the charger and the battery pack; and by means of full intelligent control, the charging optimization manager can prevent the lead-acid storage battery from being damaged due to overcharging, prevent the lead-acid storage battery from being vulcanized and realize automatic repair and restoration of the vulcanized lead-acid storage battery pack.

Description

technical field

[0001] The invention relates to the field of battery charging and battery power management circuits, in particular to a charging management circuit for lead-acid batteries, especially for comprehensive charging parameter correction, protection and automatic repair of lead-acid batteries for light electric vehicles, listed in the IPC International Classification Table It mainly belongs to the H02J subclass. Background technique

[0002] statement of problem:

[0003] At present, light electric vehicles mainly include electric bicycles, electric motorcycles, electric tricycles, electric small trucks, etc., and the domestic stock has reached more than 120 million. The batteries on each light electric vehicle are 36V, 48V, 60V, 72V etc. Calculated on the basis that each light electric vehicle is equipped with 4 batteries with a rated voltage of 12V, the number of lead-acid batteries used in light electric vehicles in the country will reach nearly 500 milli...
