How long will electric car batteries last?

Electric cars service life generally is 3 to 5 years, and electric bicycle battery changes every 1-1.5 years.

Electric cars are generally use lead-acid batteries, according to the daily use 70% of the battery capacity, cycle is one year, after a year, there is not battery, but the battery capacity is more and more small, until dry.

Expand the data

If you want to increase the service life of electric vehicle battery, pay attention to when using the following points:

1, the discharge of battery is used every time depth is smaller, the longer the pulse, the life of the battery so that no matter how hard it is to use the capacity of battery pack, users should form the good habit of increases with the increasing in charge. Often charge, often make the battery in a saturated state, as far as possible not to bring a person, meet what to introduce, avoid braking, start while moving.

2, battery should be placed for a long time when the heart must be plentiful electric power periodically, added a generally 1 ~ 2 months.

3, large current discharge of electric bicycle batteries have certain damage, when start and uphill so, please use pedal to help them.

Electric cars general service life is 3 to 5 years, electric bicycle batteries in a 1-1.5 years.

Electric cars generally use are lead-acid battery, the battery has a low cost, recycling use and so on merits, and been adopted by most of the electric vehicle production enterprises. General electric vehicle battery is one year warranty (8 months before this year if there is a quality problem in new batteries, within 4 months after in maintenance battery), so the electric car battery according to the daily use 70% of the battery capacity, cycle is one year, after a year, there is not battery, but the battery capacity is more and more small, until dry up! But, if you use a proper, often charging, the battery is often in a saturated state, when use as far as possible not to bring a person, meet what to introduce, avoid braking, start while moving. That is to say, according to the above points, you use, the battery life will significantly increase, may be two years, also may take longer time.

Due to the use and loss of normal, the normal life of a piece of lead battery is 2 to 3 years, and mobile phones, laptops and other commonly used type of battery, generally a electric cars use 2 years or so, it is suggested to replace the battery.

But with the 12 years of battery you have seen?

Yes, this is not a joke in Jiaxing, Zhejiang province ping as early as in 2015 we found a group of battery using 12 years in the day! This a little 10 ah battery it took 12 years!

Day up to 31 years, this group of cells from manufacture date has been 14 years, if can accompany days from a foolish with spirited teenager becomes a mature of the man.

Witnessed the day how steadfast walk step by step into the new energy today power battery the glory of the leader.

The proper use and maintenance of electric vehicle battery is the power source of the electric bicycle. It is a kind of consumption goods, and the price is higher, so the battery keeps good work state to prolong its service life. No matter from the environmental or economic point of view, it has great practical value. The following are some of the maintenance methods: 1, the new battery bought back to electric cars should have enough electricity to use again. Because many of the electric car in the shop has been put on hold for several months, even more than half a year, so it need to first be enough electricity before using. It had better not use immediately after adequate electricity, it needs to let stand for 10 minutes.2, charging the battery off, installation, battery wants firm, installed on the electric bicycle battery vibrates when the ride in case damage. Battery in handling, a throw, rolls, weight is prohibited.3, often clear the dust on the electric bottle caps, dirt, keep the battery dry, clean, in case the battery to discharge absolutely can't let the battery in the condition of electricity shortage for a long time, and make it a good habit to every evening for the accumulator. Long-term need not, should be full of electricity, placed a cool and dry place, and regularly charge (10 days).5, electric bicycle, when just starting to use foot (not foot the way with his feet on the ground) help starting, uphill, electric cars with the help of foot up hill, so as to avoid damage to the battery discharge current is too large.6, cycling, pay attention to not let the battery discharge, after the battery discharge to the termination voltage, continue to discharge called after discharge. Too easy to cause the battery discharge serious deficient, thus greatly shorten its service life.So the battery should try to avoid depth discharge when using, do shallow put frequently charge, generally should be: battery to discharge depth charge is 50%.Electric bicycle is generally equipped with under-voltage protection function, when the battery power is only a display when the light is bright, should shut off the power, use the foot, and as far as possible as quickly as possible to recharge battery, so as to avoid the battery discharge. Battery discharge to termination voltage resistance is bigger, the electrolyte concentration is very thin, especially plate hole and surface almost in a neutral, when the discharge resistance has a tendency to heat, volume expansion, the discharge current is larger, the obvious fever deformation, even when the concentration of lead sulfate, particularly large survival increases the possibility of the dendrite short circuit, and this will lead sulfate crystals into larger particles, which form the irreversible sulfate, will further increase the resistance, charging recovery ability is very poor, even beyond repair. When using, should prevent battery over discharge, take "under-voltage protection" is a very effective measures. In addition, due to the electric car "under-voltage protection" is controlled by the controller, the controller of some other equipment such as meter, lights and power-hungry appliances are directly by the battery power supply, the power supply is generally not controlled by the controller, electric lock switch once closed began to electricity. Although current is small, but if long time discharge 1-2 weeks will appear after discharge. Therefore, may not be long time open the lock, should immediately turn off when not in use.7, avoid overcharge, when the charger showed full stop, not a charging overnight or even days. Charging would lead to plate sclerosis of active material loss, and produce water loss and battery to be out of shape. Battery run in high temperature season, the main recharge problems existed. Summer, therefore, should try to reduce the temperature of the battery, ensure good heat dissipation, prevent the strong sunlight after charging, and stay away from heat source. Avoid charging, in addition to choose to match well with battery and charger parameters to fully understand the operation condition of the battery in high temperature season, and the changes during the whole service life. Don't put the battery overheat when using environment, especially when charging should be far away from heat source. Battery heated should take measures to cool, stay not recharged battery temperature back to normal. Battery installation location should be as far as possible to ensure good heat dissipation, found that overheating should stop charging, deal with the charger and battery for inspection. Battery discharge depth is shallow or ambient temperature on the high side should shorten the charging time.8 and avoid losing electricity for a long time, losing electricity can make the plate for a long time. Under the condition of low temperature, charging mainly accept ability difference, battery deficiencies caused by loss of battery. Cryogenic insulation anti-freezing measures should be taken, especially when charging, should be put in a warm environment, to ensure adequate electricity, prevent the formation of irreversible sulfate, prolong the service life of the battery.9, prevent it short out, should be especially careful about the installation or use of the tools used insulation measures should be taken, attachment should be outside of the battery electric even better, through inspection without short circuit, and finally connected battery, wiring specification should be good insulation, prevent overlapping compression fracture. Ban battery short circuit method to detect battery charged situation, in order to prevent the explosion casualties in battery short circuit state, its short-circuit current can be up to several hundred amperes. Contact and stronger short circuit, short circuit current, the greater the connection will produce a lot of calories, so all the weak link in calorific value is bigger, joint fuse, producing short circuit phenomenon. Battery charged local explosive gas may be produced or JiCun explosive gas, produced sparks when joint fusing, cause battery explosion; If the battery short circuit time is shorter or current is not particularly big, may not cause joint fusing phenomenon, but there will still be overheating and short circuit can be damaged by connecting strip around the binder, make its left the leakage etc. A faulty battery cannot produce, therefore, should be especially careful about the installation or use, tools used in insulation measures should be taken, attachment should be outside of the battery electric even better, through inspection without short circuit, and finally connected battery, wiring specification should be good insulation, prevent overlapping compression fracture.10, avoid large current discharge battery long time, will greatly damage the battery internal structure. Recommended start time can't more than 5 seconds at a time. Need two consecutive start, want interval between 10 to 15 seconds.11, to prevent exposure in the sun, the sun exposure can make the battery temperature increased, the activity increase of active material and the battery affect the service life of the battery.12, after the discharge of battery should be timely supplement electricity, shall not be suspended over 12 hours.
