If the thread beam system is normal after the inspection is completed, and the cause of the fault is still not found, you can use the electrical appliance to determine whether to use the electrical appliance itself.

In short, the wiring system investigation must first grasp the principle of electrical, wiring drawings, control strategies, and failure modes, and continuously accumulate experience in work, classify and summarize the failure model. In the end, it can be handy during the investigation process, identify the cause, and eliminate the failure.

4.4 Waste power battery treatment

4.4.1 The hazards of waste batteries and the treatment of various manufacturers

Most of my country's vehicle power batteries are lithium -ion batteries. Although heavy metal elements such as mercury, cadmium, and lead, waste lithium -ion batteries will cause great pollution to the environment if improperly processed. One button battery will pollute about 600,000 L water. A traditional mercury-containing battery is rotten to the ground, which can lose any agricultural value of the surrounding 1M2 land. As shown in Figure 4-43 Pollution of battery to the environment

It is estimated that by 2020, the cumulative scrap volume of pure electric (including plug -in) passenger cars and hybrid passenger vehicle power batteries will reach 120,000 to 170,000 t. Without a standard battery recycling system and advanced recycling technology, these batteries will undoubtedly have a huge harm to the environment. From the perspective of the circular economy, the recycling of waste lithium batteries is also an extremely important part of the entire industrial chain. With the expansion of production capacity, the problem of recycling will be restricted to production, affecting my country's "curve in the world of new energy technology in the world field of new energy technology The realization of the goal of overtaking.

According to statistics from the US Environmental Protection Agency, in the United States, it takes almost 100 million cars to use batteries every year, 99%of which have been recycled and used. Because American users do not return the waste batteries back to the manufacturer, retailer or wholesaler, each buy a new battery to pay more than $ 3 to 5. In a 12V conventional battery, nearly 97%of lead can be recycled. The electrolyte, especially sulfuric acid, can be neutralized, and then send other fields, such as converting into sodium sulfate to make fertilizers or dyes. Even the plastic shell of the battery can be reused.

The particularity of electric vehicles is that it cannot be scrapped and recycled metal as traditional cars. A large part of the new car costs battery costs, so a large part of the residual value when scrapped also belongs to the battery pack. Compared with other losses, the particularity of electric vehicle power batteries is that in addition to the decline in chemical activity, the chemical composition inside the battery will not change. Although the charging and discharge characteristics cannot meet the power needs of the vehicle, the battery pack is due to the battery pack. It is still a very ideal battery to make precision. Therefore, it is the ideal way to use the replaceable electric vehicle power battery recycling. It is the ideal way to use energy storage facilities.
