Abstract

The invention discloses an intermittent potential point-by-point tracking type battery charging circuit. The circuit is characterized by comprising a polarity detection circuit, a potential point-by-point tracking circuit, a charging power supply circuit and a control protection circuit. The polarity detection circuit is used for detecting the polarity of a battery, the potential point-by-point tracking circuit is used for detecting voltage changes of the battery in real time, the charging power supply circuit is used for charging the battery, and the control protection circuit is used for protecting the whole power supply circuit. Low frequency normal phase pulsating currents are used as input energy to conduct batch-type charging. The potential point-by-point tracking method is used for screening and judging the changes of potential of the battery, the charging power supply of the battery is controlled to be on and off in real time through the intermittent potential point-by-point tracking charging method, and the intermittent circulating charging is achieved.

Description

technical field [0001] The invention relates to the field of electricity, in particular to a battery charging system using a potential point-by-point tracking method for charging. Background technique [0002] The charging circuit of the existing charger is a switching power supply circuit, which is a self-excited and flyback topology circuit. The circuit characteristics of this circuit determine that the circuit efficiency can only reach 68%-85%, because only power consumption and No work is done, so the total efficiency in the whole charging process is only 68-70%. High-frequency DC charging is used. This kind of high-frequency DC charging relies on the current to slowly raise the battery voltage. This process will cause a lot of heat, and accompanied by Lots of gassing. Excessive gassing will cause the battery to lose water. The loss of water in the battery will lead to the irreversible crystallization of lead sulfate crystals, and the cycle life will decrease as the cr...
