Before charging, the lithium battery does not need to be specifically discharged. Some fast chargers only indicate that they are 90% full when the indicator light changes, and the charger will automatically change to use slow charging to fully charge the battery. But generally speaking, as long as the display is full, it can be removed. In order not to damage the battery life, it is best to charge slowly when charging; the time does not need to be too long. Mobile phone batteries have self-discharge, because over-discharge will damage the battery. If the mobile phone battery is not used for a long time, it should be ensured that the battery has a certain amount of power.

Charge it at room temperature and don't cover anything on the phone. When charging, the longer the better, the charging should be stopped after the inferior battery without protection circuit is fully charged. Separate the battery from the phone if it is not used for a long time.

The newly purchased battery does not need to be charged for 12 hours for the first use, but it needs to be fully charged and discharged for 3 to 5 hours.

Because the battery has to go through the process of filling electrolyte, forming, charging and discharging, and dividing the capacity before leaving the factory, so that the battery is in the activated state, but after leaving the factory, it takes as little as a month to more than a year to reach the user's hands. Due to the influence of discharge, the battery material becomes passivated. At this time, the battery can be activated through full charge and discharge.

Electric vehicle batteries are the source of power for electric vehicles, so the quality of the batteries is very important to electric vehicles. There are the following methods to distinguish the quality of electric car batteries:

1. Judge whether the battery is old or new through the external packaging of the battery: (1) Check whether the external packaging is damaged or disassembled; (2) Check the appearance of the battery itself to observe whether there are scratch marks and positive and negative terminals Whether the location is rusty; (3) Check whether there is an anti-counterfeiting label on the battery shell, whether the production date is relatively old, whether the manufacturer's relevant information signs are complete, and whether the writing is clear and complete. If there is 1 point or more in the external packaging of the battery, it is considered that the battery is an old battery, and the quality may be problematic.

2. Detect the quality of the battery during the trial run-install the fully charged battery on the electric vehicle, start the electric vehicle power supply, and suddenly accelerate the electric vehicle during driving, and observe the change of the electricity meter pointer: (1) If the pointer of the electricity meter drops less than half a grid during acceleration, it is judged that the battery is brand new or has good performance; (2) The pointer of the electricity meter drops 1 or even 2 grids during acceleration. If the battery is used, it is judged that the battery is old or of poor quality; (3) When the pointer of the charge gauge drops 3 or even 4 bars during acceleration, it is judged that the battery is a fake new battery after being repaired by a spent battery The products are of extremely poor quality.

A good electric vehicle battery can be used for several years, and naturally it can save more money. But in fact, the electric vehicle battery industry has mixed good and bad. Some are of superb quality, while others are very poor. The former can naturally save consumers money, and the latter, not to mention saving money, can save worry. So, how to judge whether electric vehicle batteries continue to be used with confidence?

　　 Blindly changing the battery is not advisable

　　 Recently, as the weather has become colder, some car owners gradually feel that their electric vehicles do not seem to be so "powerful". In fact, battery vehicles are not strong in winter, which is actually related to the temperature. At present, most electric vehicles on the market use lead-acid batteries. Lead-acid batteries can store electricity normally at a temperature of about 25°C. When the temperature drops, the activity of various substances in lead-acid batteries decreases, making it difficult to store electricity. The ability deteriorates accordingly.

　　 Master Li, who has been repairing battery bikes for many years, introduced that in cold weather, the capacity of the battery bike's battery becomes smaller, and it is normal that you can't ride for a long time. When the weather gets warmer, the electric car will "automatically" recover again. So as the weather gets colder, it is normal for the battery's power to decrease.

　　 Remind the general public that the battery of a battery car is not strong in cold weather. Don't think that your own electric car battery is broken and replace the battery blindly. You should check it in a regular store before making a decision.

　　 Which battery needs to be replaced

　　 1. The battery cannot be charged

If you feel that your electric bicycle battery cannot be charged, first check whether the connection of the charging circuit is reliable, check whether the connection between the cable and the plug is intact, carefully check whether the socket and plug have "fire" arc phenomenon, and wireless circuit damage Disconnection etc.

The correct usage of lithium batteries 　 Although lithium-ion batteries rarely have the memory effect of nickel-cadmium batteries, the principle of the memory effect is crystallization, and this reaction hardly occurs in lithium batteries. However, the capacity of a lithium-ion battery will still decrease after many times of charging and discharging, and the reasons are complex and diverse. It is mainly the changes in the positive and negative materials themselves. From the molecular level, the hole structure on the positive and negative electrodes will gradually collapse and block; from a chemical point of view, it is the active passivation of the positive and negative materials, and side reactions appear to be stable. Other compounds. Physically, the positive electrode material will gradually peel off. In short, the number of lithium ions that can move freely during charging and discharging in the battery is ultimately reduced.

Overcharge and overdischarge will cause permanent damage to the positive and negative electrodes of lithium-ion batteries. From the molecular level, it can be intuitively understood that overdischarge will cause the negative electrode carbon to excessively release lithium ions and cause its sheet structure to collapse. Overcharging will force too much lithium ions into the carbon structure of the negative electrode, and some of them will no longer be able to be released. This is also the reason why lithium-ion batteries are usually equipped with charge and discharge control circuits.

The unsuitable temperature will trigger other chemical reactions inside the lithium-ion battery to generate compounds that we do not want to see. Therefore, a protective temperature-controlled diaphragm or electrolyte additive is installed between the positive and negative electrodes of many lithium-ion batteries. When the battery heats up to a certain level, the pores of the composite membrane are closed or the electrolyte is denatured, the internal resistance of the battery increases until it is disconnected, and the battery no longer heats up to ensure that the battery charging temperature is normal.

Our view on battery maintenance is: 1. There is no need to deliberately ensure that the battery is discharged every time before recharging 2. A deep charge and discharge under the control of the protection circuit can be done for a period of time to correct the battery power statistics, but this will not increase The actual capacity of your battery. 3. The battery that has not been used for a long time should be placed in a cool place to reduce the speed of its internal self-passivation reaction. 4. The protection circuit is also unable to monitor the self-discharge of the battery. The battery that has not been used for a long time should be charged with a certain amount of power to prevent the battery from being over-discharged in storage and causing excessive discharge damage. In fact, the battery does not have too much attention to use, in other words, it is not very useful to take into account. How many times a battery can be used may differ more from the individual differences in the manufacture of the battery, rather than the method of use.
