Rapid nondestructive charging method of power-driven light automobile and charger

Abstract

The invention discloses a rapid nondestructive charging method of a power-driven light automobile and a charger, and belongs to the technical field of power-driven automobile charging. The rapid nondestructive charging method is characterized by comprising the following steps: step 1001, starting; step 1002, initializing hardware; step 1003, detecting whether a battery pack and the charger are matched; step 1004, alarming failure; step 1005, detecting whether a quick charging mode is carried out; step 1006, charging not quickly; step 1007, charging quickly; and step 1008, charging completely. The charger comprises a soft start protective module, an input rectification filtration module, an auxiliary power supply module, an insulation driving module, a charge control module, a power output module, an output rectification filtration module, an output opposite connection protection module and an output parameter sampling module. According to the invention, based on a slow impulse nondestructive quick charging technique, quick charging is realized, meanwhile the battery pack is nondestructive, and the service life of the storage battery pack is prolonged.

Problems solved by technology

[0002] The current electric light vehicle charger market is mostly based on conventional charging, and manufacturers often use inferior devices or reduce charger functions in order to bid, which leads to frequent charging explosions, battery drums, and premature vulcanization caused by insufficient charging. occur, and the charging time is mostly more than 8 hours, which can no longer meet the growing social life needs of ordinary people.

[0003] Although many manufacturers are aware of the above problems, due to excessive pursuit of time, they usually use unlimited high-current charging methods, which do not fully consider the charging acceptance capacity of the battery, resulting in accidents such as explosion and combustion of the battery when it is overheated, which seriously threatens personal safety.

Of course, many manufacturers use negative pulse charging to solve this problem, but from the perspective of actual application effect, it is more of an advertisement and does not get a good charging effect.

[0004] In addition, at present, 80% of domestic electric vehicle spontaneous combustion incidents are caused by ordinary chargers during charging. Since there is no automatic power-off function, ordinary chargers will continue to supply lead-acid batteries with a small current when the battery is fully charged. Charging, overcharged batteries for a long time will cause the danger of swelling or explosion and spontaneous combustion; most chargers on the market do not have the functions of automatic stop charging and ambient temperature compensation, which is also an important reason for frequent charging accidents and premature decay of battery life. one of the reasons
