 News: Recently , there have been many accidents involving electric vehicles , and several incidents have occurred in China.

 From the perspective of anti-micro-duration, I think there is a more important thing to deal with such uncertain 
power battery systems. This problem actually involves accidents like electric vehicles, soaking cars and various types of damage. Simply put, in the event of physical damage, our existing protection system is protected for a period of time, involving several groups around it:
1) Owner: Once the smoke is sent to the 4S shop to handle the warranty, if the battery involves an ordinary fire extinguisher, it will not help;
2) After-sales and related personnel of the factory: There are two kinds of designs here. There may be something that may be fine. The vehicle itself needs to be judged. It may be burned after a while, or it may be fine.
3) Firefighters: Once the fire is involved, it is basically looking at the burning or a lot of watering.

As shown in the above picture, these mechanics in the Tesla accident actually took a big risk. A very detailed consideration before is this dedicated diagnostic and maintenance tool, which is considered by GM design and development. The main purpose is to be able to access and use it at all levels.

This equipment is used under different damage conditions according to the different circuits of different electric vehicles. It is equivalent to saying that in different stages of damage of the vehicle, different access modes are used. As long as a good high-voltage connector (battery system, inverter, auxiliary power) is found through this suitable access, one can pass An external dedicated control tool reads the internal information (and provides power when the vehicle lacks 12V power) and then discharges the battery to an appropriate level.

When this item is placed in the trunk, it can be quickly connected to determine the state of the battery. If it is good, it can be placed in a safer state as soon as possible after discharge. If the internal voltage is found to be unstable, the direct soaking water should be directly soaked in water.

This tool is also useful. After dealing with battery recycling and related disposal, you can determine the actual condition of the battery and put the battery system in a relatively safe state.

Summary: With the increase in the penetration rate of electric vehicles, many disposals are in all aspects, including production, use, after-sales and recycling, and safety first. It is very easy to get on the matter. The matter is to use a reasonable disposal method. Let's talk about some of the data diagnosis about the battery here. Some data is worth exploring.
