[0005] 2) Concentration polarization - during charging or repairing, the diffusion (equilibrium) speed of products and reactants is far behind the chemical reaction speed, resulting in uneven distribution of electrolyte concentration in the middle and surrounding areas of the battery plate;
[0006] 3) Electrochemical polarization - the speed of the electrochemical reaction on the electrode lags behind the speed of electron movement on the electrode, resulting in electrochemical polarization, which seriously hinders the normal charging current
[0007] The second is the problem of lead sulfide crystals produced on the battery plate: during

Embodiment 1

[0033] Embodiment one: the repair of lead-acid storage battery

[0034] Such as figure 1 As shown, this example uses a battery repair machine to repair a group of 48V, 400AH 50% new lead-acid batteries that have been used for ten years, and provides a method for repairing lead-acid batteries, including the following steps:

[0035] Step 1, use the battery repair machine to carry out constant current, pause, discharge, pause, frequency sweep pulse, pause, discharge, pause in parallel and repeat the work process of a continuous output as a working cycle for the lead-acid battery; that is, the first Working phase 1 is the working phase of constant current and pressure limitation;

[0036] Step 2, the process of stabilizing the battery at rest; the second working stage 2 in the figure is the stable working stage of the battery;

[0037] Step 3: The repair machine supplements the charging process of the battery until the lead-acid battery obtains the rated capacity of saturation,...

Embodiment 2

[0051] Embodiment 2: maintenance charging of lead-acid battery

[0052] In this example, a group of 48V, 270AH 70% new lead-acid batteries that have been used for five years are discharged for 3.5 hours after being fully charged with the original matching charger. Charge. After maintenance-style charging, use a discharge machine to conduct a discharge test. Set the discharge parameters of the discharge machine as: stop voltage 40.8V, discharge current 54A. The result: the discharge time is 4.7 hours, and the battery capacity saturation this time is 94 %.

Abstract

The invention discloses a repair and maintenance type charging method of a lead-acid storage battery. The method comprises the following steps: a continuous and repeated constant-current restricted-voltage output process comprising constant current output, pause, discharging, pause, sweep frequency pulse output, pause, discharging and pause, a standing and stable process and a constant-voltage restricted-current complementary charging process. With adoption of the method disclosed by the invention, in the battery repair and charging process, lead sulfide crystals existing on a battery plate before repair can be broken and dissolved, three polarization phenomena including ohmic polarization, concentration polarization and electrochemical polarization and generated during charging or repair can be eliminated, formation of new lead sulfide crystals on the battery plate can be restrained, generation of high temperature of the lead-acid storage battery can be effectively prevented in repair and charging, time of repair or charging can be reduced, and the service life of the lead-acid storage battery can be prolonged; therefore, the maximum repair efficiency and the maximum capacitance of the lead-acid storage battery can be reached.

Description

technical field [0001] The present invention relates to lead-acid storage battery technology, especially the repair and maintenance charging method of lead-acid storage battery. The method of parallel output of constant current and frequency sweep pulse is adopted as a working cycle, and the work of continuously and repeatedly outputting lead-acid storage battery process. Background technique [0002] Lead-acid battery is the most widely used chemical power source in the world so far. It has good plasticity, stable voltage characteristics, large capacity, long service life, wide application range, no pollution, abundant raw material sources, low manufacturing cost, and can be The advantages of green energy such as renewable use and low cost. Therefore, the demand and application of lead-acid batteries in the market are extremely extensive, and a large amount of sales has also brought about the amount of repair and maintenance of lead-acid batteries. The existing lead-acid ...
