[0004] At present, the most commonly used is the lead-acid battery charger. The lead-acid battery charger is the most widely used in electric vehicles. Most of the current electric vehicles use lead-acid batteries. At present, the service life of electric vehicle batteries is not long. The main reason is the charging time. If it is too long, it will cause the battery to age and the safety is not high

The invention provides an intermittent high-voltage timing charger and relates to the technical field of chargers. The intermittent high-voltage timing charger comprises a control panel JX1, an IC chip U1, a photoelectric coupler U2, an operational amplifier U3A, a single-chip microcomputer U4 and a three-terminal voltage stabilizer U6. The photoelectric coupler U2 is used for isolating high voltages and lower voltages of a primary side and a secondary side, ensuring isolation of output voltages and alternating currents and guaranteeing safety in use. The three-terminal voltage stabilizer U6 is mainly responsible for controlling an output voltage loop. The operational amplifier U3A is mainly responsible for controlling an output current loop of the charger, forming an integral circuit and supplying detected charging currents to the single-chip microcomputer U4. According to the intermittent high-voltage timing charger, the single-chip microcomputer generates charging impulse currents for restoring a battery, so that the service life of the battery is prolonged; compared with a common three-stage charger, the intermittent high-voltage timing charger has the advantages of being higher in universality, having a real impulse charging mode, reducing polarization phenomena in the charging process, increasing the charge acceptance capacity of the battery, having an extremely strong restoration function and being obvious in sulfuration effect.
Description
technical field [0001] The invention relates to the technical field of chargers, in particular to an intermittent high-voltage timing charger. Background technique [0002] A charger usually refers to a device that converts alternating current into low-voltage direct current. Chargers are widely used in various fields, especially in the field of life, they are widely used in common electrical appliances such as mobile phones, cameras, and electric vehicles. The charger is a static converter device that uses power electronic semiconductor devices to convert alternating current with constant voltage and frequency into direct current. In the occasions where the battery is used as the working power supply or backup power supply, the charger has a wide range of application prospects. . [0003] There are many types of chargers, such as lead-acid battery chargers, testing and monitoring of valve-regulated sealed lead-acid batteries, nickel-cadmium battery chargers, nickel-metal h...
