Correct charging and maintenance methods for electric vehicle lithium batteries:

1. Charge according to standard time and procedure, even for the first three times.

2. When the lithium battery shows a low battery warning during the operation of an electric vehicle, it should be charged as soon as possible and in a timely manner.

3. The activation of lithium-ion battery electric vehicles does not require a special method, and lithium is used during the operation of electric vehicles

The battery will naturally activate.

4. When using a dedicated charger for charging, first insert the output plug of the charger into the battery charging socket, and then insert the charger plug into the mains socket. Observe the indicator light for charging judgment (generally, a red light indicates charging, and a green light indicates basic sufficient charge. The more discharge, the longer the charging time).

5. After the charger indicator light turns green, charge for about 1-2 hours to stop charging.

Lithium electric vehicles use environmentally friendly and lightweight lithium-ion batteries, which have outstanding characteristics such as large capacity, long service life, maintenance free, light weight, and no pollution. The service life of lithium batteries is closely related to their correct use. This article discusses the use and maintenance of batteries based on their characteristics for reference.

The new car you purchased has a semi charged battery at the factory for transportation safety. Before cycling, make sure to fully charge the battery before use, and the first charging time should not be less than 10 hours. (Note: Use the dedicated charger provided with this vehicle to charge. When the charging indicator light is green, please continue charging.)

When cycling, do not deplete the battery as it will greatly reduce its lifespan. Remember!! Because lithium batteries have no memory effect, they can be charged at any time. So you need to develop the good habit of timely charging after use, which can extend the battery life by 3-5 times.

At the same time, the battery life is also affected by the environment. The operating temperature of this product is within the range of -20 ℃ to 60 ℃. If the temperature is too high, it will affect its service life, and if it is too low, it will reduce the effective capacity by 20% -30% (affecting the driving range).

It is strictly prohibited for batteries to be exposed to rain or immersed in water.

If you do not use the battery for a long time, please charge it once within 90 days. It is strictly prohibited to store it under low voltage. Once the battery voltage reaches an over discharge state, it will cause great damage to the battery and cannot be restored.

Before using the battery, please make sure to read the "Precautions for Using WST Lithium ion Battery Pack" on the battery casing.

The low price of lithium batteries nowadays is not a myth, and the cost-effectiveness of Shunyi lithium electric vehicles is quite good. The four national ministries have issued documents to regulate the electric vehicle market, which will inevitably promote the rapid development of lithium-ion electric vehicles, so it will be very convenient to equip batteries and other accessories.

1. Do not replace the charger casually, and do not remove the speed limit of the controller

Chargers from various manufacturers generally have personalized needs, so do not replace them casually when unsure. If the required driving range is relatively long, it is necessary to equip multiple chargers for long-distance charging. The chargers that are recharged during the day should be supplemented with additional chargers, while the original chargers should be used at night. Removing the speed limit of the controller can increase the speed of some cars, but it will not only reduce the safety of the car, but also shorten the service life of the battery.

2. Protect the charger properly

The general user manual contains instructions on protecting the charger. Many users do not have the habit of reading the manual, and often only think of looking for it after the problem is solved. It is often too late, so it is necessary to read the manual first. In order to reduce costs, most current chargers have not been designed with high vibration resistance. Therefore, chargers should not be placed in the trunk and basket of electric bicycles. In case of special need to move, the charger should also be packed with foam plastic to prevent vibration. After many chargers undergo vibration, their internal potentiometers will drift, causing the entire parameter to drift, resulting in abnormal charging status. Another thing to note is to keep the charger ventilated during charging, otherwise it may not only affect the lifespan of the charger, but also cause thermal drift and affect the charging state. This will cause damage to the battery. So, protecting the charger is also very important.

3. Charging every day

Even if your driving ability is not required to last long and can be used for 2 to 3 days on a single charge, it is still recommended that you charge it every day to keep the battery in a shallow cycle state, which will prolong its lifespan. Some early users of mobile phones thought that it was best to charge the battery after it was basically used up. This view is incorrect, as the memory benefits of lead-acid batteries are not as strong. Frequent discharge has a significant impact on the lifespan of the battery. Most chargers may charge 97% to 99% of the battery after the indicator light changes to indicate full charge. Although only 1% to 3% of the battery is under charged, the impact on the driving ability can be almost ignored. However, it can also form under charging accumulation. Therefore, after the battery is fully charged, it is still advisable to continue floating charging as much as possible, which is also beneficial for suppressing battery vulcanization.

4. Timely charging

After the battery is discharged, the vulcanization process begins, and obvious vulcanization occurs within 12 hours. Timely charging can remove minor sulfurization. If not charged in time, these sulfurization crystals will accumulate and gradually form coarse crystals. General chargers are powerless against these coarse crystals, which will gradually lead to a decrease in battery capacity and shorten the battery's service life. So, in addition to charging every day, it is also important to pay attention to charging as early as possible after use, in order to keep the battery fully charged as much as possible.

5. Regular deep discharge

Regular deep discharge of the battery is also beneficial for activating the battery, which can slightly increase its capacity. The general method is to perform a complete discharge of the battery on a regular basis. The method of complete discharge is to ride the bike to the first undervoltage protection under normal load conditions on a flat road surface. Note that we particularly emphasize the first undervoltage protection. After the first undervoltage protection, the voltage of the battery will continue to rise and return to a non undervoltage state after a period of time. If the battery is used again at this time, it will cause significant damage to the battery. After complete discharge, fully charge the battery. I will feel that the battery capacity has increased.

6. Develop good habits of energy conservation

Make the most of gliding. When going downhill, try to use early power off to coast down and slow down as much as possible. Advance into taxiing when approaching traffic lights to minimize braking. A friend told me that he would rather turn the bay one more time than reduce the braking, which makes sense

When starting, it is best to add cycling assistance, which can not only improve the starting speed, but also reduce the battery's power loss and lifespan damage.

7. Pay attention to the charging environment

The optimal ambient temperature for charging is 25 ℃. Nowadays, most chargers do not have an automatic control system that can adapt to the ambient temperature, so most chargers are designed according to the ambient temperature of 25 ℃, so charging at 25 ℃ is better. Otherwise, it is inevitable to encounter issues of under charging in winter and over charging in summer. When the ambient temperature is truly 25 ℃, it is relatively low, which inevitably leads to the problem of overcharging in summer and undercharging in winter. Fortunately, most households now have indoor temperature control conditions. Therefore, when charging, it is best to arrange the battery and charger in a ventilated and temperature controlled environment.

A special reminder is that when the battery enters a warm indoor environment at low temperatures outdoors in northern winter, frost and condensation may appear on the surface of the battery. To avoid battery leakage caused by frost condensation, charging should be carried out after the battery temperature rises to a level close to indoor temperature and is dry.

8. Make full use of maintenance conditions

Many electric bicycle dealers can provide battery maintenance and repair services, and these services should be fully utilized. Some brands of electric bicycles propose battery maintenance. For example, regular maintenance of the battery can reduce damage to the battery. Repairing the state of charge of the battery can alleviate the failure of outdated batteries, which is easy for dealers equipped with repair capabilities. For dehydration, replenishing water at 70% battery capacity is more effective than replenishing water at 40% battery capacity. Even some brands of products propose that not repairing the battery within the specified time is equivalent to giving up the battery's warranty period. Causing consumers to suffer losses that should not have occurred. Therefore, consumers should fully utilize the conditions of battery maintenance to extend and increase the service life of batteries.

The correct usage of lithium batteries for electric vehicles is as follows:

1. The battery does not need to be "activated"

Lithium batteries do not require the first three charges for more than 12 hours, as they have no memory.

2. Battery charging

Use the manufacturer's designated charger for charging, and pay attention to whether the charger model matches the battery model during charging.

3. Avoid high-temperature charging

Lithium batteries should not be charged in environments with temperatures exceeding 40 ° C, as high temperatures can cause the battery capacity to decline.

4. Timely charging

Try to implement on-demand charging for lithium batteries to avoid recharging them after each undervoltage, which can greatly improve battery life. 5. Storage

When not using the battery for a long time, the connection between the battery and the entire vehicle should be disconnected, and the battery should be replenished with some electricity at intervals to avoid self discharge or over discharge due to power consumption of the protective board.
