How to "correctly" maintain electric vehicle lead-acid batteries?

With the increase in environmental awareness and urban traffic congestion, electric bicycles have become a travel choice for more and more people. However, the correct use and maintenance of lead-acid batteries, which are the core components of electric bicycles, have been ignored.

1. Correct maintenance methods for electric bicycle lead-acid batteries.

Check battery appearance regularly

Check the appearance of the working battery at least every six months to make sure there is no damage or leakage. At the same time, check whether the battery connection wires are tight to prevent looseness and increased resistance.ESS battery machine If we find that the battery appearance is damaged or leaking, we should stop using it immediately and contact professional technical maintenance service personnel for analysis, inspection and repair in a timely and effective manner.

Charge correctly

Use original chargers and avoid using chargers of different brands or models to avoid damaging the battery. Follow the charger's instructions to connect the battery and charger correctly. When charging, the e-bike should be parked in a well-ventilated area to avoid high temperature environments.Solid-state batteries After charging, unplug the charger promptly to avoid overcharging.

Avoid deep discharge

Try to keep the remaining battery power above 20% and avoid deep discharge to extend battery life. Deep discharge will cause the active material in the battery to decrease, thus affecting the performance and life of the battery.sodium ion battery When using an electric bicycle, the charging time should be reasonably arranged according to the mileage and battery capacity.

The storage environment must be suitable

Batteries should be stored in a dry and cool place to avoid direct sunlight and high temperature environments. High temperatures will accelerate the aging process inside the battery and reduce battery performance. At the same time, the battery should be avoided in a humid environment to prevent battery short circuit.

Regular charging and maintenance

Batteries that are not used for a long time should be charged every 1 to 2 months to maintain battery activity. Batteries that have been idle for a long time are prone to vulcanization, resulting in a decrease in battery capacity. Regular charging can keep the active materials in the battery active and extend the battery life.

2. Activation learning skills after the battery is "starved"

Small current charging method

Charging with a small current, say one-tenth of the battery's capacity, helps activate a "hungry" battery. Since a "hungry" battery has a large resistance, high-current charging can easily cause the battery to heat up or even bulge. Low-current charging reduces heat generation and reduces the risk of battery damage. Charging may take longer, but be patient.

Multiple charge-discharge cycle method

Performing multiple charge and discharge cycles helps awaken the battery's active materials. After each charge, let the battery discharge to 20% ~ 30% of the remaining power, and then charge again. Through multiple charge and discharge cycles, the active materials in the battery can be stimulated to rearrange and improve the performance of the battery. But please note that excessive discharge will also accelerate the aging process of the battery, so the depth of discharge should be controlled.

Replacing the charger method

Try charging with a different brand or model of charger, sometimes different charging parameters may help activate the battery. Different chargers may have different charging voltages and currents, and changes in these parameters may have a positive impact on a "hungry" battery. But please make sure that the charger you use is purchased from regular channels and is of reliable quality.

Use a professional battery restorer

Calling a professional battery repairman may help restore battery performance. Battery repairers can repair and maintain batteries through special circuits and algorithms, thereby extending battery life and improving battery performance.

But please note that not all of our "starved" batteries can be successfully activated, and the effectiveness of the battery repairer also varies depending on the development of the battery. When using this battery restorer, please follow the relevant product design instructions and pay attention to information security.
