Avoid safety measures for lithium ion battery explosion

　　1. The surface of the negative electrode will form a metal lithium

　　At present, the level of lithium ion manufacturing is still less than South Korea. Due to the consistent accuracy of Japan, the lithium ion core itself has certain safety risks. If only the BMS board with pure hardware configuration is maintained, such electronic components will have the possibility of failure. Once the BMS fails, it will inevitably lead to a production safety accident

　　The solution is to add a remote control transmission data control module to complete the data interconnection of all important electrical equipment components, including the charging data information of lithium -ion batteries. According to the company's data information monitoring and management platform, the battery failure mode, early warning users, convenient service items and security risks are predicted in the budding stage

　　2. Improve the structure of lithium battery and improve safety

　　Compared with pure electric vehicles, the application of lithium ions in electric vehicles is more extreme. The vehicle's shockproof performance is poor; complex real -time road conditions; vehicles are usually placed outdoors, and the rechargeable battery can be exposed immediately. The self -designed tailings design scheme adopts a sealing, breathable, dry, and waterproof gas structure, and the silicon rubber with high heat transfer coefficient is added inside. In addition, it also ensures that all lithium ion batteries are in the middle of the average temperature to ensure the consistency of the lithium ion battery, thereby improving the service life of the entire battery

　　3. By -way handshake identification circuit to ensure that the battery is not abused

　　Electric vehicles are based on the direct connection and discharge solutions of the sales market to facilitate users to use batteries. If lithium is used as a carrier of lead -acid batteries, that is, lead is sold in the lithium market; or as a treasure trove for trial operation, it is used for cyclic tests for lead -acid batteries; maintenance personnel will continue to use lead -acid battery control panels or charging charging Replace the lithium electric vehicle control panel and charging head. This is a bad habit of lead -acid batteries. Once a lead -acid battery vehicle is used, once the lithium is used, because the lead -acid battery control panel has the function of anti -battery charging, and it will not meet the low -voltage protection point of the lithium battery, it will generate safety risks

　　The corresponding measure is to propose a dual -wave recognition power circuit between the lithium ion battery plate and the control board, before the BMS board and the charging head. If the lithium -ion battery does not match, the charging control circuit will be closed

　　4. PGR motor avoids the reverse charging of lithium batteries

　　Resistance is a good interest point for lead -acid batteries, but it becomes a safety risk point for lithium -ion batteries

　　What is the hazard of lithium battery reverse charging? The basic principle of charging lithium ion battery is introduced in detail, that is, the lithium -ion battery from the normal stage, from the electrolyte electrolytes of the diaphragm and the lithium ion battery to the entire sliding process of high -pure graphite with a negative hole structure. If the transfer speed of the lithium -ion battery is not fast enough and the total transfer amount is too high, it will stay on the negative surface layer to produce lithium branches crystals. The main factor affecting the total transfer volume and transfer rate of lithium -ion batteries is the working temperature and current

　　Although all lithium ion cars have eliminated the effect of the bicycle, there are still reverse charging currents in the entire downhill process. When the rated power of the motor exceeds the rated speed ratio, the operating voltage of the self -induced electromotive force will be higher than the battery voltage, and the kinetic energy will flow back to the charging battery. The faster the vehicle drops, the higher the magnetic sensing of the magnetic induction, the larger the reverse current

　　Especially when the maximum speed of the national benchmark electric vehicle is limited to 25kmh, the downhill slip speed will exceed 25kmh, and the reverse current will be large. Especially in the cold winter, the conductivity of the electrolyte of lithium batteries is reduced, the transmission rate of lithium -ion batteries is reduced, lithium branches crystals of negative metal materials are more likely to change, and the diaphragm is more likely to produce. The battery life decreases faster, especially in a large area of short -circuit heating, and eventually lost control and burning.
