What are the precautions for the first use of electric vehicle batteries?

Many consumers will discharge the electric car battery once buying electric cars. Many people believe that electric vehicle battery needs to discharge before charging for the first time usage. In this way, it can make the battery storage have more power; In fact, on the contrary, electric vehicle battery which discharges after first use needs to recharge first, what the reason is this?

Battery from production to the factory to the dealer's hand, loading to consumers use, the process a little bit delay time, to the consumers use probably already factory for one to two months, during this period, the manufacturer will give a full charge, then place, in the process of placing, the battery will discharge, part of the energy consumption, place the longer, the lower the ultimate power, until (till) the final formation of electricity, is look like electricity, but actually has no electricity.

Used in this case, inevitably will appear two situations, one is a lot of consumers think electricity capacity is not big, in a short while, the other is excessive discharge, harm the electric car battery.

The service life of the batteries is a year to a year and a half, some cells are of good quality, can use to two years or three years, if the maintenance of good even longer, but the premise is to maintain good. One of the reasons for excessive discharge is in violation of the premise. Can lead to excessive discharge electrode plates on the active material cannot complete chemical conversion, eventually forming some dead already, and with these cannot be used more and more, the electric capacity will be less and less, life will be more and more low.

Suggest when you first use in electric vehicle battery charging after discharge, in addition to the above reasons, but also because there are several benefits:

First, to the traction battery maintenance good, easier to extend your life

After any family or personal bought electric hope that electric cars can be used for a long time, but because of various factors lead to shorten the service life of the battery, for this, preferably maintain a little bit better, it can not only prolong life, still can save money.

Second, life is good

Good electric vehicle battery life is good, can bring great convenience to the user, in particular the high quality of electric vehicle batteries. Imagine that one can easily take you to the beyond of electric vehicle batteries, a place only to close the electric car battery, which one do you prefer? Needless to say, must be the former.

Should not be ridden a charge: the battery life is determined by the charge and discharge cycles, should to correctly grasp the number of charge and discharge, charge and discharge attenuation the faster, the more life cycle life of lead-acid battery, generally replaced every year or two, so, should not be just ridden a electric vehicle charging, should grasp the depth of discharge the battery recharging.

Charging time should not be too long: many electric vehicle charging users think that the longer the battery power is enough, this is very wrong charging time within extending from the general with the charger light changes is the best for a long period of time the overcharge deformation phenomenon such as filtration, easy to cause the battery to directly harm the battery life.

It is forbidden to lose electric driving: some users have been recharging the electric motor to move, thus seriously hurt the battery performance, depth discharge will greatly shorten the battery life for many times, if the power is not enough on the way ahead of cadence best power, to avoid depth discharge, a charge must be full of, don't use, can reduce the service life of the battery, try to avoid at ordinary times faster to charge the charging station.

Do not charge under the condition of the temperature too high or too low: in the process of charging the battery itself will produce a small amount of heat, charge under high temperature, can make the body temperature, damage to the battery performance; Temperature is too low, the battery to accept ability is poor, activity is abate, battery, charge and discharge frequency increases, shorten the battery life.

Can overload, especially not in the uphill section of overload, because suddenly increase current, and can cause damage to the battery, easy to cause the motor controller to burn out.

Loss of electric power for a long time are prohibited: when will you have a period of time without the use of electric vehicles, first place the charged;1 month apart added 1 times report.

7. Every 1 to 2 months on the depth of the battery discharge 1: the battery after using for a long time there will always be some active substances of the precipitation, if you don't timely activation active substance, is bound to cause certain decline to the battery capacity.

8. Often watch the stand or fall of the charger: between new battery charging process are generally, if the charging time is too long to check whether the charger voltage protection device damage, battery charging for a long time can cause deformation, deformation of the battery is not manufacturer warranty scope.

9. To prevent sunlight insolates battery: the battery cannot charge immediately after exposure, otherwise it will cause the battery cracking or deformation, rechargeable must wait after cooling.

Electric vehicle battery heated to take measures to cool, wait for electric car battery may be recharged only when temperature back to normal. The installation position of electric vehicle battery should as far as possible to ensure good heat dissipation, found that when overheating, should stop charging, battery charger and electric inspection. Electric vehicle battery discharge depth is shallow or when the environmental temperature on the high side should shorten the charging time.

Charging will increase the water loss of electric vehicle batteries, will accelerate board gate corrosion, active material softening, will increase the risk of deformation of electric vehicle batteries. Should try to avoid the happening of charging; Choose a good match with electric car battery charger parameters, to fully understand the running status of electric vehicle battery in high temperature season, and the changes during the whole service life. Don't put battery in overheating when using environment, especially when charging should be far away from heat source.

Electric car battery

To prevent over discharge

Electric vehicle battery discharge after the termination voltage, continue to discharge called after discharge. Over discharge would result in grave damage to electric vehicle batteries, electrical performance and cycle life of the battery.

Electric vehicle 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 apparent heat deformation (or even fever), the concentration of particularly large, there is greater likelihood of dendrite short circuit, and at this point into a larger particles, namely the formation of irreversible salinization, will further increase the resistance, charging recovery ability is very poor, even beyond repair.
