Correct charging method and maintenance method of new energy vehicle

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.

Future electronic connectors are faster, smaller, smarter and more environmentally friendly
When the Internet of things and industry 4.0 become the new market engine, the component manufacturers such as te have a long way to go. In James' view, the core of these market hotspots is simply the word "connection", the connection between cars, the connection between household appliances, and the connection between security facilities, including in industrial applications, the connection between equipment. It's just that the requirements for connectors are getting higher and higher.
In the future, the requirements of connectors are nothing more than faster, smaller, more intelligent and more environmentally friendly. For example, the automotive industry needs to ensure the reliability and high quality of connectors in a harsh environment. For the consumer electronics industry, lightweight is the most important thing, followed by reliability. However, the reliability of the two is not the same level. To a certain extent, the speed of the innovation of consumer electronic products determines two other special requirements: cost control and R &amp; D cycle shortening.
In addition to the technical iteration, the regional distribution of connectors also varies with the change of market share. Over the years, the global connector production capacity has begun to transfer to Asia, especially to China. Some analysts believe that Asia has become the place with the most development potential in the connector market, and China is expected to become the fastest growing and largest market for connectors in the world.
In the past, most connector suppliers made more use of China's low production costs. Now they are thinking more about how to serve this emerging market. The answer given by te is to transform the original mode of "made in China" into "made in China".

Technical requirements for charging station of electric vehicle
With the gradual promotion and industrialization of electric vehicles and the increasing development of electric vehicle technology, the technical requirements of electric vehicles for charging stations reflect a consistent trend, requiring charging stations to be as close as possible to the following objectives.
1. Fast charging
Compared with Ni MH and Li-ion power batteries with good development prospects, traditional lead-acid batteries have the advantages of mature technology, low cost, large battery capacity, good load following output characteristics and no memory effect. However, there are also some problems such as low specific energy and short driving range of primary charging. Therefore, in the current situation that the power battery can not directly provide more driving range, if the battery charging is fast, the fatal weakness of short driving range of electric vehicles can be solved in a sense.
2. Universal charging
In the market background of coexistence of various types of batteries and voltage levels, the charging device used in public places must have the ability to adapt to various types of battery systems and voltage levels, that is, the charging system needs to have a wide range of charging, and has a charging control algorithm of various types of storage batteries, which can be charged with different battery systems on various types of electric vehicles It can be charged according to different batteries.
3. Intelligent charging
One of the most critical problems restricting the development and popularization of electric vehicles is the performance and application level of energy storage batteries. The goal of optimizing the intelligent charging method of battery is to realize the charging of non-destructive battery, monitor the discharge state of battery, avoid over discharge, so as to prolong the service life of battery and save energy. The application technology development of intelligent charging is mainly reflected in the following aspects:
Optimized and intelligent charging technology, charger and charging station;
Calculation, guidance and intelligent management of battery capacity;
Automatic diagnosis and maintenance technology of battery fault.
4. High efficiency of electric energy conversion
The energy consumption index of electric vehicle is closely related to its operating energy cost. One of the key factors to promote the industrialization of electric vehicles is to reduce the energy consumption of electric vehicles and improve their economy. For the charging station, considering the power conversion efficiency and construction cost, the charging device with high power conversion efficiency and low construction cost should be preferred.
5. Charging integration
In line with the requirements of miniaturization and multi-function of the subsystem, as well as the improvement of battery reliability and stability requirements, the charging system will be integrated with the energy management system of electric vehicles, integrating transfer transistors, current detection and reverse discharge protection and other functions. Without external components, the charging system can realize a smaller and more integrated charging solution, thus providing an electric vehicle with a higher integration The rest of the components can save the layout space, greatly reduce the system cost, optimize the charging effect and prolong the battery life.

Distinction of connector, connector and terminal
2020.08.28
1、 First of all, distinguish the concept of "connector", "terminal" and "connector"
① Connector, or connector. Also called connector. It is a kind of component that electronic engineering technicians often contact. Also known as connectors, plugs and sockets. Generally refers to electrical connector. It is a device connecting two active devices to transmit current or signal.
② Connector is a kind of positioning joint connecting electronic circuit, which is composed of two parts, namely plug-in and connector. In general, they can be completely separated. The similarities between switch and connector lie in the change of contact state of their contact pairs to realize the purpose of conversion of the connected circuit. The essential difference is that the plug-in connector only has two states of insertion and removal, and the switch can be in two states It can realize the circuit conversion on the ontology, but the connector can't realize the transformation on the ontology. The contact pairs of the connector have a fixed corresponding relationship. Therefore, the connector can also be called a connector.
③ Terminal, English name terminal. Is used to achieve electrical connection of a kind of accessories products, industry is divided into the category of connectors. The terminal is used to facilitate the connection of wires. It is actually a piece of metal enclosed in insulating plastic, with holes at both ends, which can be inserted into the wire. Terminals can be divided into wuk terminal, European terminal series, plug-in terminal series, etc.
2、 Distinguish "connector", "terminal" and "connector" from the scope of ownership
① "Connector = connector" is the first category, and the terminal is only one of the "connectors"
What's the difference between a connector and a connector?
Connector is the connection of line to line; connector is the connection between line and board and box. In real life, people often refer to the same thing vaguely.
② The terminal is part of the connector. Connector is a general term. In fact, the common connector we usually see includes two parts: the housing and the terminal. Housing is mostly plastic and plays a protective role, while terminal is a metal, which plays a general role.
