Problems solved by technology
[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

Embodiment Construction
[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0022] Such as figure 1 As shown, an intelligent timing electric vehicle charger includes a control board for controlling various charging actions and protections of the charger. The first pin of the control board is connected to the base of the first triode Q1, and Q1 It is a field effect tube, through its switching action, the transformer stores and releases energy; the collector of the first triode Q1 is divided into two circuits, one is connected to the twenty-fifth resistor R25, and the other is connected to the second pin, one end of the twenty-fifth resistor R25 is grounded, and the twenty-fifth resistor R25 is the current-limiting sampling resistor on the primary side week by cycle, which limits the start-up inrush current, protects Q1 f...

The invention discloses an intelligent timing electric vehicle charger, and relates to the technical field of chargers. A circuit primary side is composed of a rectifying circuit, a transformer main winding, an auxiliary winding, a switch circuit, an absorption circuit, a turn-by-turn current limiting circuit and a control circuit. A secondary side is composed of a secondary side output main winding, a secondary side auxiliary winding, an output voltage sampling part, an output current sampling part, a control display LED lamp loop and a control fan loop. According to the intelligent timing electric vehicle charger, the technical problem that a single-chip microcomputer is disturbed by a high-frequency circuit is solved, an intermittent pulse high-voltage timing charging mode is adopted, the problem that a lead-acid battery is prone to being charged to be swelled in summer and short in discharging mileage in winter is solved, and the service life of the charger is prolonged.
Description
technical field [0001] The invention relates to the technical field of chargers, in particular to an intelligent timing electric vehicle 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-meta...
