Electric vehicle battery vulcanization removing charging device manufactured by small-power power transformer

Abstract

The invention relates to an electric vehicle battery vulcanization removing charging device manufactured by a small-power power transformer. A plurality of electrolytic capacitors are connected in series to realize the step-down of electric supply, a silicon rectifier diode is utilized to perform half-wave rectification, and a small-power power frequency power transformer is utilized to generate one-way silicon controlled trigger impulse, so that a trigger impulse circuit is simple and reliable; and although the charging device is not a charging device of a pure transformer without a power supply, a cumbersome master power transformer is thrown away, the problem of the isolation of an alternating-current power grid from the charging device is solved, and the hazard of electric shock of operators can be prevented effectively. The vulcanization removing charging device manufactured by the technical scheme can excite inert materials such as large-crystal lead sulfate and the like in a battery, so that the inert materials are converted into active materials to continue participating in electrochemical reaction and have the good vulcanization removing effect on an accumulator battery, the battery is fully charged and the service life of the battery is effectively prolonged. The electric vehicle battery vulcanization removing charging device can lighten the weight of the charging device effectively and reduce the consumption of non-ferrous metal substantially and the manufacturing cost; in addition, the vulcanization removing charging device has the characteristics of small volume, light weight, small running noise and the like.

Description

technical field [0001] The invention belongs to the technical fields of electronic technology and storage battery charging, and relates to a charging device for desulfurization of batteries of electric vehicles produced by small-power power transformers. Background technique [0002] The large capacity and high cost performance of lead-acid batteries (batteries) are unmatched by various rechargeable batteries at present, so they have been widely used. In particular, the successful research and development and popularization of maintenance-free batteries have made them more widely used. At present, the batteries used in electric bicycles generally use maintenance-free lead-acid batteries as the power source, so the performance of the batteries directly affects whether the electric bicycle can work normally. Therefore, how to use and maintain batteries is the most concerned thing for consumers. The battery charger is a supporting device for electric vehicles. Although the ba...

AI Technical Summary

Problems solved by technology

[0004] 2. The battery is often running in a state of power loss, or is often in an over-discharge state

[0005] 3. If the charging time of the battery is too long, it will cause the battery to lose more water, and the electrolyte (dilute sulfuric acid) will dry up prematurely due to water loss, which will easily cause the battery to bulge and deform, and the service life of the battery will be terminated prematurely.

[0006] 4. Using overcharging or charging with a large current can increase the effect of desulfurization lead, but the effect is very small and it will damage the performance of the battery

[0007] 5. General chargers have no inhibitory effect on the formation of lead sulfate (saltization) of the battery plate when charging (although the battery has a great tolerance for charging technology), and the sulphate of the plate is an irreversible process

[0009] The use of industrial frequency power transformers has always had problems such as large volume and weight, while the use of switching power supplies has practical problems such as high production costs and easy damage.
