Electric car battery maintenance technology ten questions ten answer!

As a time-saving, low-carbon environmental protection of electric vehicles, low-key home with a small electric, high-profile play cool electric cool car, it can be said that people already travel home travel necessary. So, the increasingly high utilization of electric vehicles which parts the most important? This also asked? Must be battery!

Battery, is the electric car, "the heart, have its kinetic energy, have to run the electric car. Such an important battery, as a woman's face, timely maintenance and repair, in order to longer life! Today, Serena teacher For everyone to bring electric car battery ten questions ten answer! All dry goods Oh ~

Q & A

1. Electric car long parking, how to treat the battery?

Very simple Oh, in order to protect the battery, we can fully charge after the deposit, and at least once every other month, so that it can effectively solve the battery formation of irreversible salt and crystal short circuit.

2. Do you need to empty the charge before charging?

Just as the phone nowadays, electric car battery is not necessary to completely empty the power, then go to charge, you can always charge.

3. Do you need to charge the battery for the first time?

It is necessary. The battery in the factory to use, usually after 2 months or so, and even a longer time, will naturally be stored in the consumption of part of the electricity, so it is necessary to make supplementary charge, so that we mistakenly believe that the battery capacity does not meet the instructions marked power.

4. Excessive charge or insufficient charge, is it harmful to the battery?

Yes, not only have, or great harm! Overcharge over the battery rated current, the most direct impact is the battery temperature rise, long-term cause a lot of water loss, serious or even deformation of the fault. Lack of charge, then the harm is long past, the capacity will be smaller again and again, give us the feeling that the battery is more and more disabled.

5. The battery is often charged and vent power, which is more good for the battery?

Both of them are not good for batteries. The battery is often charged, if the encounter is a good high-quality batteries, it is ok, rechargeable to help protect the battery life, but for the market circulation of the battery, in addition to ultra-Wei batteries and other brands, low failure rate, quality Stability, the majority of there are different problems, charge over and over but to hurt its fundamental, affecting the battery life; battery empty and then recharging, not good, because the battery load for a long time, it is easy to damage the battery.

6. Is there a direct relationship between voltage and capacity?

not at all! Voltage is the voltage, the power is the power, and can not say that the high voltage on the high capacity, low voltage low capacity, however, in the case of load, the battery voltage is related to the battery power, and even can be said to be proportional.

7. What are the hazards of excessive battery use?

Electric car battery if used too much, this will cause the battery overheating, resulting in the battery sulfuric acid material reduction, the concentration reduction, will cause a special material generation, it is easy on the plate to form a thick hard crystal, Will cause the battery to accept the power of the ability to reduce the use of the battery capacity.

8. Is the battery rated capacity in relation to life?

Have. The battery capacity is affected by the active substance and utilization. Electric Bicycle battery size must be, the quality of the plate has been limited to a certain extent, only to improve the utilization of active substances in order to improve capacity. To improve the battery capacity, will inevitably increase the porosity, increase the content of PbO2, sulfuric acid specific gravity, but these measures will accelerate the softening of the positive plate, resulting in accelerated battery life attenuation, charge and discharge process of active substances will produce expansion, contraction (especially positive plate) , The deeper the depth of discharge, the greater the amount of active material expansion and contraction, the more accelerated the softening of the active material. Therefore, the initial capacity of a large number of direct impact on the battery charge and discharge times.

9. What happens when we need to charge the battery for maintenance? What do you need to pay attention to?

When the situation occurs: 1. Battery capacity becomes too fast; 2. Battery deterioration is damaged; 3. Battery loss after liquid, after fluid; 4. Battery for a long time; 5. Excessive use of the battery; 6. Battery length Time in the harsh environment; 7. long-term to maintain the lack of charge, is the need for maintenance of the battery charge. The caution is to charge the original charger voltage, there is a multi-stage constant current charge.

10. Is battery performance related to temperature?

High temperature, high capacity to charge, easy to charge power; low temperature, it is difficult to charge power, so ah, we in daily use, we must pay attention to can not cause the charger and battery temperature changes too fast, so that the direct cause of the battery Of the charging performance, and sometimes the battery will cause harm.
