What are some tips for maintaining electric vehicle batteries?
Today, more and more car owners are purchasing electric vehicles, which are environmentally friendly and save money, and the state also provides subsidies and A support. This is also the reason for the rapid development of the electric vehicle industry. . However, friends who are used to driving gasoline vehicles don't know much about how to maintain electric vehicles. This issue will give you a detailed explanation of the most important component of electric vehicles: the battery.
1. What are some tips for maintaining electric vehicle batteries?
1. Do not choose fast charging frequently
The consequences of frequent fast charging are accelerated battery polarization and battery life is greatly reduced. ThereAC slow charging will make electric vehicle batteries more durable.
2. Do not overcharge or discharge too frequently
Most batteries used in pure electric vehicles are ternary lithium batteries. Its characteristic is that the lower the degree of deep discharge, the longer the battery life. Therefore, the service life of lithium batteries with superficial charging and discharging is the most guaranteed.
3. Even if the electric vehicle is not driven, it must be recharged at least once a month
This helps prevent battery loss due to prolonged non-charging.
2. What are the maintenance items for electric vehicles?
Compared to fuel vehicles, the maintenance items of electric vehicles are relatively simple. Without an engine, the general environment of the car will not be very hot, soc the oil used will not deteriorate easily, and there will be no filters, throttle valves, spark plugs and other wearing parts to filter impurities.
Pure electric vehicle maintenance mainly focuses on daily maintenance, including daily maintenance of batteries and motors. But like fuel vehicles, it is also divided into major maintenance and small maintenance.
Minor maintenance is routine maintenance: chassis inspection, headlight inspection, tire inspection, etc. are the same as those for fuel vehicles, except there are more inspections of batteries and motors. The main goal is to eliminate the problem. Generally, minor maintenance does not require replacement of materials, but these items require paid inspections because they require reading information through computer data, which is more complicated than inspectionfuel vehicles.
Major maintenance requires replacement of materials: for example: replacement of air conditioning filter, coolant, gear oil, brake fluid, etc. However, the mileage of major maintenance usually reaches 40,000 to 60,000 kilometers, which is also very worry-free and free.
Overall, compared to this period, the maintenance costs of pure electric vehicles are much lower than those of gasoline vehicles. However, currently only 4S stores have relatively complete maintenance conditions, so it is better to upgrade to 4S. stores for maintenance as much as possible.
Will lithium batteries be damaged if not charged for a long time?
Mobile phone battery maintenance methods:
1. usage habits and do not wait for recharging when it is fullkeep the power off, and do not overload continuously for a long time. Lithium ions like to be discharged and charged shallowly. Of course, it is very difficult for an average user to always remember when to load or close software and other power-saving operations.
2. Once the "fast charge" stage is complete, the charge is actually about 80% complete and the battery still has plenty of charge space. In fact, lithium-ion batteries also have “continuous charging”; charging" and "trickle charging" processes. You can use third-party battery management software to monitor the battery's state of charge so that it can play a greater role at critical times. /p>
In fact, it is important to develop good electricity consumption habits, closing some unnecessary software in time can also save energy.For example, turning off WiFi, Bluetooth and other devices when there is no network can also extend standby time.
4. Often, when the mobile phone tells you that the battery is low, the battery is already quite low. If you continue to use it, it will easily cause excessive discharge, which will have a great impact on battery life. Kingsoft Battery Doctor can customize low battery reminders and intelligently switch to power saving mode.
5. Currently, almost all mobile phones use lithium-ion batteries. There is no memory effect and there is no need to charge for 12 hours. Additionally, excessive charging and discharging of lithium-ion batteries will result in permanent damage to the positive and negative electrodes of the battery. Overcharging results in too many lithium ions being incorporated into the carbon structure of the electrodee negative, which prevents the release of certain lithium ions, shortens battery life and also poses safety risks.
6. The entire process of charging a cell phone battery involves three stages: fast charging, continuous charging, and trickle charging. After the first two steps, although the system power shows 100%, the battery has not yet reached saturation. At this point, the remaining capacity can only be replenished by tiny impulse currents. This step usually takes 30 to 40 minutes. Only when all three stages are completed can the battery truly reach a good state of saturation.
7. In order to prevent users from overcharging and causing accidents, mobile phone batteries are designed with overcharge protection circuits, that is, the charging process will stop automatically.only after charging is complete. However, the battery will also start a self-discharge process, causing a drop in power; once the power reaches a certain level, it will start charging again and the discharge-charge cycle will continue. However, staying in a high voltage state for a long time will have a negative effect on the battery and cause crystal precipitation and adhesion, which will not only shorten the battery life, but also pose safety risks.
8. Using a mobile phone while charging will cause damage to the mobile phone, people and the battery. Since the voltage of the mobile phone battery during charging is higher than during standby, if operations such as making and receiving calls are performed at the same time, the voltage at the time of making a call or connecting to the network will be several times higher than usualtude, causing the mobile phone to malfunction easily; secondly, the voltage of the mobile phone during charging radiation is also higher than usual.
9. Use your cell phone as little as possible when charging. Plus, the lithium-ion battery doesn't have to worry about repeated charging interruptions, so you can unplug the power when you need to make a phone call or play games. It can be used normally, but do not charge it in a bad charging environment. Unstable voltage will damage the battery.
10. Lithium batteries have no memory and like to be charged and discharged shallowly. They can be loaded at any time. However, if the battery cannot be fully charged inadvertently, it is likely that there is a problem with the charger or the battery itself. It is recommended to repair or replace it in time.to avoid any danger.
11. Although the iPad charger is compatible with iPhone, it is best not to mix. After all, the iPad charging adapter can provide relatively large power, and in extreme cases it can damage the cell phone battery.
12. Generally, the original charger has a rated output voltage of DC+5V and an output current of 1A; while the standard output voltage of PC general USB port is also 5V and the output current is 500mA. According to this data, as long as the computer is grounded. Good. There is no quality problem with the USB interface. It is entirely possible to charge with a USB data cable, but the theoretical charging time is twice as long as with the USB data cable. charger. It's just "slow charging".

This helps better protect the battery
First: Do not charge the phone to play games or use other applications that cause consumption extreme energy of the phone. or heat, it is mainly because excessive battery temperature will cause excessive battery loss. Try to avoid excessive use of mobile phones (such as playing games) when the ambient temperature is 35 degrees Celsius below room temperature. When you play games, eParticularly for large-scale mobile games, try to ensure smooth ventilation of the phone and do not play games that put heavy strain on the CPU and GPU in an environment where the temperature is too high. Second: Do not overcharge and unplug as soon as possible after fully charged. Although today's mobile phones have overload protection functions, some mobile phones will still overheat if plugged in for a long time. The operating temperature of the battery has a certain range. Too high or too low temperature will significantly shorten the life of the lithium battery. Third: Try to charge the phone before 20% of the battery remains. If there is no other way, please turn on power saving mode if the battery is below 20% (applicable to all mobile phones). Excessive energy consumptions lithium batteries is one of the leading causes of human casualties! Therefore, unless there are special circumstances, please invoice on time. Fourth: Make a habit of charging on the go and recharge your mobile phone regularly, which will help maintain the life of the lithium battery and avoid excessive attenuation of the lithium battery capacity. In case the full charge and discharge is not observed (i.e. the charging process from less than 5% to 100%), this is not counted as the number of cycles of the battery . However, it is best to cycle and charge properly once every one to two months, which will help maintain lithium battery activity. Fifth: If you do not use your cell phone for a long time, please store the cell phone battery with more than 50% of the power and make sure it est stored in an environment with appropriate humidity and temperature, in order to avoid battery. loss to the greatest extent.
