Problems solved by technology

Judging whether the battery is fully charged during the charging process is an important indicator of the charger. If the battery is not fully charged and the wrong judgment is full, the battery will be undercharged, otherwise it will cause the battery to be overcharged. Both of these situations will seriously affect the battery. life

Embodiment Construction

[0041] Such as figure 1 Shown, a kind of lead-acid storage battery charging method comprises:

[0042] Step 1: Select a charging mode, which includes normal charging mode, emergency charging mode and maintenance charging mode;

[0043] Step 2: Charging, charge the battery according to the charging steps in the selected charging mode;

[0044] In the normal charging mode, the charging method includes the following steps:

[0045] Step 1: Charge with a constant current of 0.05C for 2 minutes;

[0046] Step 2: Judging whether the battery voltage has risen to 98% of the rated voltage, if the result is yes, go to step 11, otherwise go to the next step;

[0047] Step 3: Charge with a constant current of 0.3C for 2 minutes;

[0048] Step 4: Determine whether the battery voltage has risen to 90% of the rated voltage, if the result is yes, go to step 6, otherwise go to the next step;

[0049] Step 5: Perform pulse charging until the battery voltage reaches 90% of the rated voltage...

Abstract

The present invention discloses a lead-acid battery charging method, multiple charging modes are set. In the normal mode, according to battery capacity, charge batteries in multi-stages. The corresponding charger is disclosed which comprising of: high-power switch power supply, switch circuit, impulse charge-discharge circuit, voltage and current detecting circuit, charge mode switch module and micro-processor. Comparing to present technique, the present invention sets multiple charge modes, charges in multi-stages, meets the charge requirement in all different conditions furthest, and benefits for prolonging the service life of lead-acid battery. The pulse charge-discharge circuit of present invention realizes discharge energy circumfluence by capacitance serial-parallel conversion, uses high inductance converting steep wave pulse to ladder-type pulse, comparing to traditional pulse charge-discharge circuit using big resistance charge and discharge, reduces the energy loss and loss of rapid pulse to lead-acid battery electrode slices.

Description

technical field [0001] The invention relates to a charging method for a lead-acid storage battery and a charger thereof. Background technique [0002] As an energy transfer device or backup power supply, lead-acid batteries are widely used in various electric locomotives, electric bicycles and automation equipment. Ordinary charging methods need to back up other batteries due to the long charging time. The charging process of the battery has a great influence on the charging time and life of the lead-acid battery. Most of the batteries are not used but damaged. To shorten the charging time of the lead-acid battery and improve the service life of the lead-acid battery, the design of the fast pulse charging controller in the charger plays a vital role. [0003] The charging methods of existing chargers usually include constant current charging, stage constant current charging, constant voltage charging, improved constant voltage charging, fast charging and pulse charging.
