Maintenance Guide for Electric Vehicles

First, correctly grasp the charging time

After the new car is proposed, it must be recharged in time to keep the battery in full state. In the process of use, according to the actual situation to accurately grasp the charging time, reference the usual use of frequency and mileage, self-control charging time. When running normally, if the electricity meter indicates that the red light and the yellow light are on, it should be charged; If only the red light is left, it should stop running and charge as soon as possible. Excessive discharge will shorten the battery life. The charging time should not be too long, otherwise it will form excessive charging, causing the vehicle battery to heat up. Excessive charging, excessive discharge and insufficient charging will shorten the battery's service life. During the charging process, the battery temperature exceeds 65 °C and should be stopped charging.

II. Protect Charger

There are instructions on the protection of chargers on the instructions for the use of new energy vehicles. Many users do not have the habit of reading the instructions carefully. They often have problems before they think of looking for the instructions. In addition, it should be noted that when charging, keep the charger ventilated, otherwise it will not only affect the life of the charger, but also may affect the heat drift effect charging, causing damage to the battery.

III. Regular Deep Discharge

Regulations on the Administration of Access to New Energy Automobile Manufacturers and Products(Revised-Draft for Consultation)

The new energy vehicle manufacturers and their products access management rules(revised version-draft for consultation) are exposed. New energy vehicles should not only meet the inspection standards for conventional automotive products, but also meet the special inspection standards for new energy automotive products. The consultation draft shows that these rules shall come into force as of the date of publication. Requirements "From July 1, 2016, the new declaration of new energy automotive products and the change of extended products should meet the requirements of the" New Energy Vehicle Products Special Inspection Projects and Standards "in Annex 3 to these Rules; As of 1 July 2017, all products in production should meet the requirements of Annex 3. "

A periodic deep discharge of the power battery also facilitates the "activation" of the battery, which can slightly increase the battery capacity. After the battery has undergone the first low voltage protection, the voltage will rise after a period of time and return to a non-low pressure state. If the battery is used again, the battery will be greatly damaged. After completing the complete discharge, the battery will be fully charged and the battery capacity will be increased.

IV. Maintaining Adequate Electrical Power

In daily use, new-energy vehicles must maintain the battery's foot state and control the speed. The best mileage is 1/3 -- 2/3 of the longest mileage. If you travel about 10 km to 20 km a day, it is best to replenish electricity once every two days; If you travel more than 50 kilometers per day, you should supplement the electricity on the same day so that the battery is "full" for a long time. With a few days idle recharging, easy to appear vulcanization, battery capacity drop.

Avoid heating plugs when charging

Loose power plugs or charger output plugs, contact surface oxidation and other phenomena will lead to plug heating, too long heating time plug short-circuit or poor contact, damage charger and battery, causing unnecessary losses. When the above situation is found, you should remove the oxide or replace the plug-in in a timely manner.

VI. Loss of electricity during storage

Vehicle batteries are strictly forbidden to be in a deficit state when stored. The deficit state refers to the battery that has not been charged in time after use and stored the battery in the deficit state. It is easy to undergo sulfuric acid salinization. Lead sulfate crystals adhere to the plate, which will block the ion channel, causing insufficient charging and battery capacity. drop. The batteries of new energy vehicles need to be adequately stored and recharged once a month to maintain the battery's healthy state and avoid long-term power loss that causes the battery plates to lose sulphuric acid. The longer the vehicle is idle, the heavier the battery damage.
