Reasonable charging method of lead-acid battery

New energy vehicles and gradually become a new trend in the development of the automotive industry, because new energy vehicles solve the problem of air pollution from the root cause, and there are many advantages compared with fuel vehicles, although the current technology is not very mature, but the pace of development cannot be ignored, one of the new energy vehicles on the used lead-acid storage batteries, then this is how the battery charge of it?

Lead-acid battery charging method introduction: Introduction

The electrode is mainly made of lead and its oxide, and the electrolyte is a battery of a sulfuric acid solution. English: Lead-acid battery. In the discharge state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charged state, the main components of the positive and negative electrodes are lead sulfate. It is divided into exhaust battery and maintenance-free lead-acid battery.

The battery is mainly composed of a tubular positive plate, a negative plate, an electrolyte, a separator, a battery tank, a battery cover, a pole, and a liquid injection cover. The electrode of the vented battery is composed of an oxide of lead and lead, and the electrolyte is an aqueous solution of sulfuric acid. The main advantage is that the voltage is stable and the price is cheap; the disadvantage is that the specific energy is low (ie, the energy stored per kilogram of battery), the service life is short, and the daily maintenance is frequent. Old-fashioned ordinary batteries generally have a life span of about 2 years, and the height of the electrolyte is regularly checked and distilled water is added. However, with the development of technology, the life of lead-acid batteries has become longer and the maintenance is simpler.

The most obvious feature of a lead-acid battery is that it has a screw-open plastic sealing cap on top and a venting hole. These filling caps are used to fill pure water, check electrolytes and vent gases. In theory, lead-acid batteries need to check the density and level of the electrolyte at each maintenance, and if necessary, add distilled water. However, with the upgrading of battery manufacturing technology, lead-acid batteries have developed into lead-acid maintenance-free batteries and gel-free maintenance-free batteries. Lead-acid batteries do not require the addition of electrolyte or distilled water. The main purpose is to use the positive electrode to generate oxygen to absorb the oxygen in the negative electrode to prevent the water from decreasing. Lead-acid water batteries are mostly used in tractors, tricycles, and automobile starters, while maintenance-free lead-acid batteries have a wider range of applications, including uninterruptible power supplies, electric vehicle power, and electric bicycle batteries. Lead-acid batteries are divided into constant current discharges (such as uninterruptible power supplies) and instantaneous discharges (such as car start-up power) according to application needs.

Lead-acid battery charging method introduction: correct charging

First, the charger

The lead-acid battery charging method is very important, and the correct charging method can effectively extend the service life of the electric vehicle battery. It is best to use the original charger to charge the battery of the electric car. When the electric bicycle is shipped from the factory, the charger is matched with the configured battery. The supplementary current, the maximum charging voltage and the switching current, the floating charging voltage, and the floating charging current are specified. The parameters of other chargers have a certain range of differences, which may not match the configured battery, so it is not free. Replace the charger.

Second, the charging environment

Since the charger will generate a certain amount of heat during the charging process of the electric vehicle battery, it is recommended that the battery be placed in an empty and ventilated place for charging. It is strictly forbidden to cover the charger with foreign objects during charging, otherwise the charger and the battery may be damaged or even cause a fire accident; It is also strictly forbidden to be flooded or rained.

Third, charging time

Use lead-acid batteries, to develop the habit of charging on the same day of use, after riding an electric bicycle every day, no matter how far the ride is full of electricity, do not wait for electricity to recharge, so as not to shorten due to "deep discharge" Battery Life. Also do not charge the battery when it is upside down. A fully charged battery should be recharged once a month if it is not used for a long time.
