How to prevent the theft of lithium batteries for electric vehicles

Several ways to prevent battery theft:

1. Remove the handle from the battery box so thieves cannot remove it.

2. For the battery placed in the pedal, you can install an anti-theft cover and go to the welding sales department to seal the battery box with a metal plate. So that thieves cannot attack easily, this method is currently proven by many people to be a feasible method!

3. For the battery placed under the seat cushion, the seat cushion and the Frame must be locked with a Lock. Let the thief easily remove the seat cushion and remove the battery!

4. Another simple method is to add double-sided foam tape around the battery case. The double-sided foam tape is very sticky and the battery is difficult to remove easily. done The car is loaded.

5. Install a vibrating alarm in the battery box. If it is snatched by a thief, the battery case will continue to ring.

6. Another super stupid method is to bring the battery home every day when not in use and reinstall it when in use. Probably no one would go to that much trouble.

In short, to prevent battery theft, the main thing is to increase vigilance and strengthen prevention awareness. In addition to using all kinds of locks, you should also be careful not to leave the car unattended or in the dark. and sparsely populated places.

Lithium iron phosphate batteries can be tilted downward, taking "lithium batteries for electric vehicles" as an example, they can be tilted sideways for a short period of time, but not often. Most vehicle batteriesElectric vehicles can be placed upside down, but those containing acid cannot be used. They should not be charged backwards, otherwise sulfuric acid will leak and the battery will be damaged. To determine if the battery can be added with acid, check if the battery cover can be opened. Whether it is a lithium battery or a nickel-metal hydride battery, there is no problem whether to put it upside down or not. If it is a lead acid battery, it generally cannot be reverse charged.

Lead-acid batteries currently used in electric vehicles are all sealed colloidal electrolyte batteries, which can be placed sideways or upside down. In the car battery box, if you take it apart and look at it, you can see whether it is placed vertically or horizontally. This type of battery does not need to beouted with water, and water cannot be added.

Note: Electric vehicle batteries are generally maintenance-free lead-acid batteries. The difference from regular lead-acid batteries is that there is a sponge-like object sandwiched between the plates. , and the electrolyte has just been adsorbed there, no matter how it is placed theoretically, the electrolyte is sandwiched between the plates, and the charging and discharging effects are the same. However, if the battery is of poor quality, the electrolyte will still leak. Lead acid batteries generally cannot be reverse charged. Lithium batteries and nickel-metal hydride batteries have no problem being placed upside down or not.

Three major taboos of lithium batteries: temperature Lithium batteries are afraid of high temperatures. Large current, for example, 18650 ceBattery cells are discharged at 3C and electric vehicles are 8000W. The battery cells used are lower than the discharge current of electric vehicles. This will cause the lithium battery to be too high in temperature, current. be too large, and the service life will be shortened, and it will also cause the case to bulge and be scrapped. Electric vehicles are very powerful and very fast. It is recommended to choose 18650 batteries with a current of 10C. It is obviously very important to choose the right battery.

Store at full charge. The full charge of the ternary lithium battery is 4.35V. The market protection board stops charging at 4.2V. Generally, when storing an electric vehicle lithium battery for a long time, a full 50% charge is best. If the full charge is stored for a long time, the capacitylithium battery tee will decrease. Except for lithium iron phosphate and lithium titanate, be sure to choose a better quality protective board.
