Pulse energy-saving charging method and pulse energy-saving charger

Abstract

The invention provides a pulse energy-saving charging method and a pulse energy-saving charger. The method comprises the following steps: detecting the voltage of a battery, and activating and charging the battery if the voltage of the battery is lower than a preset voltage; pre-charging the battery by adopting a second preset current or a second positive-negative pulse current; carrying out trickle charge for the battery by adopting a third preset positive-negative pulse current; carrying out the primary charge for the battery by adopting a fourth preset current; carrying out the secondary charge and constant-voltage charge for the battery by adopting a fifth preset current or a fifth preset positive-negative pulse current; stopping the charging for the battery; carrying out the floating charge for the battery by adopting a seventh preset positive-negative pulse current; carrying out the maintenance charge for the battery by adopting an eighth preset positive pulse current; detecting the voltage of the battery in real time, restarting the battery in a feed manner when the battery voltage is lower than an eighth preset voltage, and skipping to the pre-charging step. According to the method, the negative pulse charging way is adopted, so that the current receiving capability of the battery is improved, the service life of the battery is prolonged, and the battery can be automatically restarted when the battery is idle for a long time or is fed so as to be recharged and repaired.

Description

technical field [0001] The invention relates to the technical field of battery charging, in particular to a pulse energy-saving charging method and a pulse energy-saving charger. Background technique [0002] Most of the common chargers on the market are three-stage and ordinary multi-stage chargers. The above-mentioned chargers have the following defects in the charging process: [0003] (1) The charging process is mainly main charging, high constant voltage and secondary charging. The charging process is simple, and the charging current and voltage of the battery cannot be accurately detected and adjusted during the charging process. Moreover, a constant charging current is easy to form an inert reaction layer on the electrode plate, which hinders the electrochemical reaction of the battery. [0004] (2) Some batteries that are damaged or placed for a long time have a very low voltage at the beginning of charging. If they are directly charged with a large current, the bat...

Problems solved by technology

[0003] (1) The charging process is mainly main charging, high constant voltage and secondary charging. The charging process is simple, and the charging current and voltage of the battery cannot be accurately detected and adjusted during the charging process.

Moreover, a constant charging current is easy to form an inert reaction layer on the plate, hindering the electrochemical reaction of the battery

[0004] (2) Some batteries that are damaged or placed for a long time have a very low voltage at the beginning of charging. If they are directly charged with a large current, the battery plates will be seriously damaged, or they are pre-charged directly with a small current, although they can be charged into the battery. But the battery capacity will decrease

[0005] (3) When some batteries are being charged, the charger and the battery will be connected for several days or even months. Generally, after the battery is fully charged, it will always be floated or turned off, causing the battery to be damaged by floating charge or naturally discharged to cause the battery to be scrapped.

[0006] (4) When users need to know the usage status of one or more machines and batteries, they cannot know in real time, let alone remotely control the machines

During the charging process, the charging status cannot be displayed in real time, and the charging process cannot be well grasped
