Abstract

The invention discloses a frequency-conversion charger. The frequency-conversion charger comprises a circuit control board, a storage battery, a frequency-conversion circuit, a voltage transformation circuit, a current adjuster, a charging circuit and a power supplying circuit. The power supplying circuit is connected with the circuit control board. The circuit control board is connected with the frequency-conversion circuit and the voltage transformation circuit. The frequency-conversion circuit is connected with the current adjuster after being connected with the voltage transformation circuit. The current adjuster is connected with the charging circuit. By means of the mode, the frequency-conversion charger is suitable for products such as digital products, electric tools, electric bicycles and electric automobiles; the frequency-conversion circuit, the voltage transformation circuit and the current adjustor are adopted, the charging process can be suspended at intervals, and the frequency-conversion charger has the advantages that the charging speed is high, the charging quantity is enough, and the charged battery does not crystallize and does not dehydrate or produce heat.

Description

technical field [0001] The invention relates to the field of chargers, in particular to a frequency conversion charger, which is suitable for digital products, electric tools, electric bicycles, electric vehicles and other products. Background technique [0002] Existing rechargeable batteries mainly include lead-acid rechargeable batteries and lithium batteries. These rechargeable batteries are widely used in mobile digital products, power tools, electric bicycles, electric vehicles, golf carts, electric buses and other equipment. Whether the above two kinds of rechargeable batteries can be fully charged quickly, and the charged batteries have a longer discharge time and extended service life, is an important symbol for judging the quality of the charger. [0003] The existing charger charges the rechargeable battery continuously and with a constant current, so the above-mentioned serious problems of the charging quality of the rechargeable battery degrading and even causi...
