Problems solved by technology

The high-power charging and discharging equipment in the domestic market is still mainly in the power frequency mode, and the equipment is bulky and bulky, and the efficiency is low; the high-frequency charging and discharging equipment mostly adopts the full-bridge or half-bridge working mode, which is always in the low current output state, charging and discharging. Discharge uses two sets of discrete circuit devices
The charging control process inside the machine, the charging time is long, the temperature of the battery rises, and the temperature is difficult to control, which causes the battery electrolyte to volatilize quickly, which greatly reduces the battery capacity and shortens the normal service life of the battery

Abstract

The invention relates to a recharge and discharge machine, in particular to a high-power portable intelligent recharge and discharge machine. The high-power portable intelligent recharge and discharge machine comprises a machine case and an electric main circuit arranged in the machine case, wherein the electric main circuit comprises a microprocessor control circuit, a sampling circuit, a recharge and discharge control circuit, a three-phase bridge type rectifying filter circuit, a soft start circuit, a PWM control and drive circuit, an IGBT module circuit and a two-way LC filter circuit; and the sampling circuit is connected with a detection current divider in the two-way LC filter circuit. The high-power portable intelligent recharge and discharge machine greatly reduces the volume andthe weight of equipment under the condition of keeping a high-current output state to meet a requirement on portability, greatly improves the efficiency, can recharge and discharge a storage battery by automatically adopting different optimal recharging and activating functions according to different changes of the environment climate temperature, improves the volume of the storage battery, and prolongs the normal service life of the storage battery.

Description

Technical field [0001] The invention relates to a charging and discharging machine, in particular to a high-power portable intelligent charging and discharging machine. Background technique [0002] Batteries are currently the world’s largest production and most versatile energy product. For a long time, people have been studying and exploring how to improve the charging quality of batteries and shorten the charging time, so various charging and discharging devices have appeared. The high-power charging and discharging equipment in the domestic market is still dominated by the power frequency mode, the equipment is large and bulky, and the efficiency is low; the high-frequency charging and discharging equipment mostly adopts the full-bridge or half-bridge working mode, and is always in the state of low current output. Two sets of discrete circuit devices are used for discharge. The charging control technology in the machine has long charging time, increased battery temperature,...
