Recovery and quick charge device of lead acid accumulator

Abstract

The invention relates to a lead-acid battery restoring and fast charging device which comprises a filter, a wave filtering rectifier circuit, a voltage change feedback control circuit, a negative pulse generation circuit and a CPU central processing unit. The filter transmits filtering signals to the wave filtering rectifier circuit; the wave filtering rectifier circuit changes 220V AC power into 308V DC power which is output to the voltage change feedback control circuit; the voltage change feedback controlling circuit changes the 308V DC power into 20kHz pulse power which is output to the negative pulse generation circuit; the negative pulse generation circuit and a half bridge circuit are used for detecting the magnitude of positive current and negative current and the potential charged into the battery; the CPU central processing unit processes whether the charging of the battery is finished and controls charging state and processes whether the charging current and voltage meet the receptance curve (Malus law) of the lead-acid battery. Compared with a plurality of imported intelligent restoring equipment and fast charging equipment, the device realizes equivalent effect, greatly simplifies the circuits and also greatly lowers cost.

Description

Lead-acid battery recovery and fast charging device technical field The invention relates to a device for repairing and rapidly charging a battery, in particular to a device for realizing the recovery and fast charging of a lead-acid storage battery by utilizing the reverse recovery time of a diode and using a pulse electric excitation method. Background technique Lead-acid battery is a traditional product with a history of more than 150 years. It has the characteristics of large capacity, reliable performance, and low price, and is widely used in the economic field. Automobiles, electric vehicles, motorcycles, railways, mines, communications, computer UPS power supplies, control switch systems, lighting alarm systems, photovoltaic energy storage systems and military power systems are inseparable from lead-acid batteries. However, waste lead-acid batteries have caused serious pollution to the environment. The lead and acid pollution of lead-acid batteries have brought grea...
