Daily maintenance of electric car lithium battery tips, do you understand?

Mar.20.2020 106

After the implementation of the new national standard for electric vehicles, lithium battery, as a new type of energy storage battery, is gradually replacing the traditional lead-acid battery.Compared with lead-acid batteries, lithium batteries have many advantages such as high energy ratio, small size, light weight, environmental protection and no memory effect.

With the prevalence of lithium battery, its daily maintenance also affects the hearts of countless consumers.

What should daily maintenance of lithium battery pay attention to?

The charger must match.

The charger should be fully matched with the lithium battery, and lead acid battery charger should not be used directly. Excessive current of the charger will break down the lithium battery protection system and cause short circuit, thus causing safety accidents of lithium battery.The voltage of the charger is too low, making the charging efficiency low and consuming too much time.

Master the correct charging method.

Connect the charger to the battery pack first, and then connect the charger plug to the 220V ac power supply. According to this connection sequence, electric sparks can be avoided when plugging and unplugging the charging plug.The charger shows a red light when the power is on.

Keep in mind the light charge.

The basic principle to follow when using lithium batteries is light charging and light discharging, that is, to charge in a timely manner, do not wait until the battery is almost dead to recharge, to ensure that the battery voltage is maintained in a stable state.Deep discharge (more than 90% of capacity) and recharging can easily damage the battery.

When a lithium electric vehicle is not in use, the power should be turned off in time, or the battery pack from the battery stand out.Because the motor and controller will still consume power in the no-load state.In particular, when long-term parking, it is best to conduct a similar "activation" charge and discharge every month, so as to avoid the occurrence of battery electrode passivation, damage to the electrode structure, and then affect the battery life.

Avoid contact with metal contacts, so as to avoid metal objects touching the positive and negative electrodes of the battery, resulting in short circuit and damage to the battery;Do not knock, prick, trample, refit, insolation battery at the same time, lest cause danger.

For the daily travel of electric vehicles, daily maintenance do not ignore yo!
