Embodiment Construction

[0022] The present invention fully considers the characteristics of the electrochemical reaction between the current positive charging and positive and negative combined pulse charging between the battery plate and the dielectric, and changes the aging and charging process in the biochemical state after assembly from the current general six-charging and five-discharging system Or four charging and three discharges, three charging and two discharges and other multiple charging and discharging curing systems are reformed into one charging curing system. The charging method of the present invention divides the curing charging into two stages and completes it at one time. The characteristics of each stage are:

[0023] In the first stage, the new battery in the biochemical state is charged in the forward charging mode until the battery is charged to 70% of the rated capacity;

[0024] In the second stage, the battery is continuously charged to the rated capacity with a combination ...

Abstract

The method divides procedure of continuous charge into twp phases. In first phase, 70úÑ rated capacity is charged by forward pulse. In second phase, using positive-negative combined pulse in certain duty ratio continues charge. Devices adopted in the method include no steady-state pulse triggering circuit, positive pulse charging circuit, negative pulse charging circuit, and first position switcher. The no steady-state pulse triggering circuit is composed of IC chip ICl - IC3, resistance R2 - R9, and capacitance C4 - C8. The positive pulse charging circuit includes diodes, controllable silicon and resistance. The negative pulse charging circuit includes variable resistance, bipolar trigger tube and controllable silicon etc. The said switcher is composed of triode, regulator, variable resistance and relay etc. Comparing with system of charging for six times and discharging for five times, the invention carries out charging for only once to reach performance index and service life.

Description

Technical field: [0001] The invention relates to a charging method and equipment for storage batteries, in particular to a charging method and equipment for a new battery that utilizes combined pulses to realize biochemistry and can be matured by charging only once and leaving the factory after six charging and five discharging. Background technique: [0002] After the battery is assembled in the production plant, it is still in the biochemical stage. It needs to be charged and discharged a certain number of times according to the specified procedures, technical conditions and parameters, so that its aging can reach the technical state specified in the factory standard. The process has been used since 1882 by the chemist Gladstone. The six-charging and five-discharging system is usually used in foreign countries. Because the curing process of this battery requires a lot of material resources, financial resources and time for the manufacturer, which increases the product cost...
