What should pay attention to power battery maintenance?

With the widespread use of electric vehicles, the replacement cost of electric vehicle batteries continues to rise, and how to extend the battery life has become one of the concerns of consumers. So, how can the electric car battery be more durable? After the reporter learned about it, he summed up the following experiences.

Lead-acid batteries: At present, most electric bicycles are lead-acid batteries. Their working characteristics are small discharge current, long electricity consumption, deep discharge depth, and no charging when driving. The longer the driving distance, the deeper the depth of discharge, such as 30 to 40 km per day, the depth of discharge is 60% to 80%. Electric bicycle batteries should use a deep-charged power battery.

Nickel-metal hydride battery: As a sealed battery, Ni-MH battery is convenient to work in any position, weighing about 10 kg. Compared with ordinary lead-acid batteries, it not only has a low level of secondary pollution, but also can be charged and discharged at any time, recycled, and without maintenance. Overcharge and over-discharge are used as one use, and it is expected to be used about 1000 times.

Lithium battery: The lithium battery adopts three layers of protection measures, which can be overcharged and discharged, making it safer and more convenient to use. It has four characteristics: small size, light weight, long service life and environmental protection (no need to recycle). A set of batteries weighs only 4 kilograms, such as the size of a children's crayon, which can be installed in the basket.

However, the current electric bicycles on the market are still mainly lost in recycling, and the colloidal lead-acid batteries which have secondary pollution to the environment are mainly. Due to the high cost of nickel-metal hydride batteries and lithium batteries with better environmental protection effects, the price of electric bicycles equipped with these two types of batteries is high and the penetration rate is low. In the future, hydrogen-burning batteries and carbon nanotubes (a charged container that discharges like a faucet) will be the development direction of electric bicycle power sources.

Prevent short-lived eight points to pay attention to

Experts remind that the battery should pay attention to the following 8 points:

1. The battery should be charged in time after the battery is exhausted. If it is left for a long time without power, it will damage the battery;

2. When the full light is on, it means that the battery can be used or basically fully charged, but there is still a gap from 100%. It is recommended to charge the battery for a long time every week or every two weeks, that is, when the full light is on, continue charging. The time is controlled in about 16 hours;

3. Pay attention to check the air volume of electric vehicles, not too much in summer, and keep enough in other seasons to save electricity;

4. Do not recharge the battery after it is completely discharged. The greater the depth of discharge, the shorter the battery life;

5. If the electric bicycle is not used for a long time, charge the battery before placing it, and check the power at least once a month.

6. If it is not electric motorcycle, the effect of adding anti-theft device is not great, and the burden of the battery is increased;

7. If the riding distance is about 15 kilometers per day, the estimated battery life is 2 years;

8. If the battery is overheated during charging, stop charging and check it out.

Four maintenances extend battery life

In order to make the battery work better for electric vehicles, experts recommend that it is important to maintain the daily maintenance of the battery.

First, the battery should be installed firmly on the electric bicycle, avoiding disassembly and assembly, so as to avoid the battery being damaged by vibration under different use conditions. Always remove dust and dirt from the battery case, and keep the battery dry and clean to prevent the battery from discharging itself.

Second, the battery should not be close to the high temperature heat source. During the high temperature season, it is strictly forbidden to directly expose to the sun (especially in the summer). Pay attention to good ventilation when charging. The battery should be charged in time after use. The next time you use it to ensure the next trip. Smooth.

Third, when the electric bicycle is just started, try to use the pedal boost to start, so as to avoid damage to the battery due to excessive discharge current, and the battery cannot be over-discharged during riding, which may cause serious battery power loss, thereby shortening its service life.

Fourth, the electric bicycle load exceeds the assembly, resulting in an increase in the motor current, causing over-discharge of the battery and premature battery aging, which seriously affects battery life.

It should be noted that if the battery is found to be broken or electro-hydraulic leakage, the battery should be replaced in time to avoid acid corrosion. The electrolyte of the battery is corrosive. Do not get on the skin or clothing, and avoid splashing into the eyes. In case of the above, immediately rinse with clean water and immediately send it to the hospital for treatment.
