Announcement for the usage of lithium ion battery of electric vehicle

The reasonable usages of lithium battery of electric cars are as following:

1.The battery do not need to "activate"

Lithium battery does not need to be the first three time charge more than 12 hours, lithium battery no memory.

2, the battery

When using the charger manufacturers specified charging, charging and pay attention to whether the charger model matches the battery model.

3, avoid high temperature

Lithium-ion batteries do not charge under the environment of temperature more than 40 °, high temperature can make the battery capacity decline.

4, timely charge

For lithium battery increases with the increasing use of charging, as far as possible to avoid the battery recharging after under voltage, every time so that we can greatly improve the battery life.5, store

Should be when do not use the battery for a long time not connected, the battery and the interval and a period of time to add some power, avoid the battery self-discharge, or power battery protection board.

Fear of excessive lithium-ion batteries charging more afraid of excessive discharge. But lithium batteries have no memory effect, can be in charge. Don't completely run out before charging, so easy to damage excessive discharge the battery; Don't large current discharge, where the steep, it is best to pedal power, to avoid the battery current is too large, affect the battery life. In the same way, should avoid loading more than specification. Charger usually have full protection, generally will not result in a charge, but the night when the network load is light, high voltage rises, easily more than set full automatic stop voltage charger, and will continue to charge the battery, the cause of charging, night, the charger should go down.

The correct ways of using the electric lithium battery are as follows:

1, the battery does not need to "activate"

This company USES of lithium batteries don't need the first three time charge more than 12 hours.

2, the battery

When using the charger manufacturers specified charging, charging and pay attention to whether the charger model match the battery model.

3, avoid high temperature

Lithium-ion batteries do not charge under the environment of temperature more than 40 °, high temperature can make the battery capacity decline.

4, timely charge

For lithium battery increases with the increasing use of charging, as far as possible to avoid the battery recharging after under voltage, every time so that we can greatly improve the battery life.

5, store

Should be when do not use the battery for a long time not connected, the battery and the interval and a period of time to add some power, avoid the battery self-discharge, or power battery protection board.

If you have other questions, can ask!

Recently due to the weather temperature drop, plus a large area of rain and snow weather, lithium battery electric vehicle in use process may appear: differential pressure alarm, power indicator is not allowed, monomer charge it into electricity, short range and speed up the problem such as power, shifting gear. When the occasional these phenomena do not be afraid of, perhaps your car does not appear the quality problem of the real, is only affected by low temperature, if the failure phenomenon for a long time can't remove, can again to the manufacturer designated service station for inspection. To remind the lithium battery users:

1, the inclement weather such as rain and snow, please try not to charge, cover mouth good electric charge at the same time, although the charging port is done waterproof processing, but long time exposure in damp environment, internal metal also can appear rust, oxidation, etc., affect the charging efficiency and security. When charging is completed in a timely manner to charge gun (plug) unplug, prevent the charger and the management system for a long time in the standby state affects the service life and other properties. When the trolley in the process of charging or power and charger without output current, please remove the charge gun, in order to prevent the battery system in an open position for a long time, consumption of automotive lead-acid battery, lead-acid battery supply.

2, air temperature is low in the morning, try not to charge when the battery internal temperature is low, even if has a heating film battery pack, in the short term only chamber (batteries) surface temperature of the battery charging temperature, heated to management system allows but at the moment, the temperature of the batteries is still in a lower status, then charging efficiency is not high, it will also affect battery life. Advice: for this trolley use recharging after a period of time, because of the lithium battery discharge will generate heat, batteries at this time the temperature will rise, can the normal charge, or parked the tram to the higher temperature indoor for a period of time (more than 15 ℃) (best) greater than 5 h, when the battery internal temperature rise again after charging in time, but you can't use fire baking or heating equipment, it may produce safety issues. Trams as far as possible when don't let be consistently in electrical traction power state (> 70%) of the SOC,

Note: the small electric bicycle batteries can take down mentioned indoor charging, but as far as possible in the case of someone recharged during the day, lest produce other anomalies.

3, trams at the bottom of the ice to clear in time, although the battery casing external has paint protection, but use after period of time will have scratches and knock against and ice can lead to a battery box body rust, affect the appearance and use fixed number of year, it will also make the battery for a long time under low temperature, affect the performance and life of the battery.

4, in low temperature environment of the actual capacity of lithium-ion batteries to slant below normal temperature environment capacity, is approximately 80% of the normal temperature, the individual may be lower in the northern areas, thus will seriously affected the range of electric vehicles, a range without obvious far before. But don't worry, because of the influence of low temperature capacity can recover, when the temperature slightly higher, the loss of capacity can be restored.

5, north the ambient temperature is low, don't worry as far as possible when using lithium battery trolley speed, especially in power less than 70% of the time, because of the low temperature environment, lithium-ion battery discharge platform will decline, catching up will cause the batteries voltage fell sharply, to management system setting threshold voltage, discharge protection cause alarm, the problem such as the speed limit, shifting gear. When your trolley running appears weak and not to electricity, please check the batteries voltage from your screen, if the single batteries voltage is close to 3.1 V (lithium iron phosphate), at this time that the battery has no electricity, need to charge in time, even the SOC is still in the high level.

6, power indicator (SOC) is not allowed, due to the effect of storage, temperature and so on, trolley using 1 years later there will be a power indicates the phenomenon, no need at this time with the aid of the display screen of the actual power of monomer to determine the battery voltage, when the battery monomer voltage close to 3.1 V (lithium iron phosphate), as the battery quickly without electricity, need to charge in time, even if the SOC may also showed 30%, 40%, and other power (this time may be associated with alarm with differential pressure big, monomer low voltage alarm, and the trolley shifting gear, etc.).When the voltage of battery monomer in between 3.20 3.45 V (lithium iron phosphate), proof of batteries or electricity, can be at ease use. Because of the battery management system with automatic calibration function of SOC, even when the SOC is allowed to come along, don't worry, just filled several times can automatically recover, for individual without automatic calibration function of the old system, need to the manufacturer designated service station it is ok to upgrade the system.

7, trams don't where there is a large amount of water stored for a long time, even now the battery is waterproof, waterproof but only for short periods of time, if under water for a long time, the battery through the answer the socket is likely into the water, such as lithium-ion batteries and power management system, and car electric parts are very afraid of water, once the water is likely to lead to short circuit batteries and system components damage, produce other security hidden danger. So when the trolley bubble water or for a long time in the water surface when using, please timely to the manufacturer designated service station for maintenance.

8, Keep the trolley or battery with electricity when they don't work for a long time (SOC > 80%), so as to prevent power consumption due to long-term storage systems, or it may lead to  battery discharge.
