I believe that many people know that the emergence of new energy vehicles in recent years has provided great help to our life. At the same time, many friends will choose to buy new energy vehicles. However, some people ask Xiaobian how to charge new energy vehicles correctly? Today, I will tell you how to charge new energy vehicles correctly.

1. In order to keep the battery fully charged, every day riding an electric scooter, no matter 10-50km, should be recharged to make the battery in a "full state" for a long time. Moreover, the battery will be charged on the same day, and it will be recharged after being idle for a few days. It is easy to lead to plate vulcanization and capacity reduction.

2. Carry out regular deep discharge: it is recommended to carry out a deep discharge after two months of use, that is, long-distance riding until the under voltage indicator light flashes and the power is used up, and then charge to recover the battery capacity. It can also know the current capacity level of the battery and whether it needs maintenance and protection.

3. No power loss storage: the storage battery with low power will seriously affect its service life. The longer the idle time is, the more serious the battery damage will be.

4. Regular inspection: if the mileage of the new car is 50km, and there is a serious reduction within three months, such as more than ten kilometers, at this time, you can use a multimeter to check the voltage value of the battery external terminal. Generally, the full charge should be 39-42v. If several volts are less, or open the battery box

If the voltage of one battery is lower than 10.5V, it may be the internal single cell short circuit. At this time, you should find a maintenance station to repair and replace it to avoid damaging the other two good batteries. Also check the charger for failure.

5. The designed load capacity of the electric scooter is 75kg, so avoid carrying heavy objects. Please use pedals to assist when starting and uphill. Because the motor current increases at this time, the battery discharges too fast and the voltage drops rapidly. The smaller the discharge depth of the battery every time it is used, the less the discharge depth is

The longer the service life of the container. Therefore, reducing the high current discharge can prolong the service life of the battery and increase the driving range. In addition, no matter how large the capacity of the battery pack, users should develop the good habit of charging with use.

6. In winter, the battery capacity decreases with the temperature, which is a normal phenomenon. Taking 20 ℃ as the standard, the capacity of - 10 ℃ is generally 80%.

7. Keep the battery surface clean for a long time. Do not expose the car to the sun when storing it. Keep the car in a cool, ventilated and dry place.

(1) The smaller the discharge depth (the shorter the distance) every time the battery is used, the longer the service life of the battery will be. At ordinary times, the good habit of charging with use should be formed, and the battery should always be fully charged.

(2) The charging time should be different according to the driving distance. The longer the mileage, the longer the charging time. Otherwise, the shorter the charging time. The charging time should be controlled within 4-12 hours. Long time charging is not allowed.

(3) When the battery needs to be placed for a long time, it must be fully charged first. Generally, it should be replenished once a month.

(4) High current discharge has a certain damage to the battery, so when starting, climbing, loading and windward, use the foot to help.

(5) When charging, a matching charger should be used. It should be placed in a cool and ventilated place to avoid high temperature and humidity. Do not let water enter the charger to prevent electric shock.

There are certain statements when all things are charged, so you must use the correct method when charging. OK, today's Xiaobian tells you how to correctly charge new energy vehicles. I hope that the narration of Xiaobian can help you.

Quality inspection of AC charging pile for electric vehicle

Charging and improving charger performance is the key to management. What are the advantages of the electric vehicle charging pile? There are several charging piles. Since the birth of the fast and environmentally friendly electric vehicle, it has been favored by the public, but the charging difficulty has troubled the "electric vehicle family". Electric vehicle charging pile is mainly composed of charging motor, charging module, metering module and charging gun. It has the functions of electric energy measurement, billing, communication monitoring, etc. the charging motor and charging module are the main parts of electric vehicle charging pile, and they are important components of charging quality of electric vehicle charging pile. Their cost is not high, accounting for about half of the total charging cost. Individual overload measurement barcodes can only be written in digital English, about 18 bytes, which can only be recorded in one way, and can be translated into Chinese, just like commodity code, it can record the place of origin, production date, manufacturer, etc. When the charging rate is less than C / 100, the capacity of the battery can be restored to 100%, which shows the response of overcharge. Charging enterprises also need to increase the research and development of fast charging technology, and create a higher charging speed on the premise of not losing or shortening the life of the battery, so as to create their own barriers. The function of the charging pile is similar to that of the filling device inside the gas station. It can be fixed on the ground or on the wall, and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels.

Some traditional charging shed is installed by the company. In order to make profits, the company will charge higher fees to the users of the traditional charging shed. Because the power of electric vehicle charging motor is generally small, AC charging pile realizes fast charging, so AC charging pile is also called slow charging. The input end of charging pile is directly connected with AC power grid, and the output end is equipped with charging plug for charging electric vehicle. To restore battery capacity to 100%, some overcharge reactions must be allowed. From the current market situation, although the charging pile has broad development prospects, but due to the problems of nonstandard operation and difficult cost reduction, the industry has not entered the "profitable" track. There are signs on the charging point to store the link address of background program of charging management application software of electric vehicle. It has overload and under load functions. In China, the construction of electric vehicle charging station is still relatively small, most of the electric vehicle charging piles are scattered in various parking lots or charging stations or buildings.

In addition to the same safety performance as the intelligent charging pile, the charging box of electric vehicles can also be used outdoors, rain proof and lightning protection. In order to prevent fire caused by high temperature during charging, each charging box is equipped with smoke alarm device and dry powder fire extinguisher, which makes the charging of electric vehicles safer. When the rated power is large, the power supply will be cut off automatically. The charging station receives the discharged battery, and then customizes the charging scheme in the stages of fast charging, normal charging and trickle charging. The output power of AC charging pile is not large, generally 5 kW, 7 kW, 15 kW and so on. Although the construction speed of energy vehicle charging pile is very fast, it also meets and supports the increasing charging demand and charging mileage of electric vehicles. In order to facilitate the property management of electric vehicle charging, electric vehicle owners can easily and timely charge. The electric vehicle charging station has been developed and rapidly rising. But there is a device called electric vehicle charging pile on the streets of this country, which brings great convenience to people's electric vehicle travel. There are two main charging methods: ordinary charging and fast charging. People can swipe the card on the human-computer interaction interface by using the special charging pile charging card to realize the corresponding charging mode, charging time, charging data printing and other operations. The charging pile screen can display the charging amount, charging data, charging time and other data.
