What are the safety measures for lithium battery explosion?

1. Safety measure 1: Software BMS protection board, remote security monitoring. Nowadays, the domestic battery cell manufacturing level does not reach the consistency accuracy of Japan and South Korea. The battery itself has certain security risks. If only a pure hardware BMS board is used for protection, There is a probability of failure of such electronic components. Once the BMS fails, a safety accident will inevitably occur. Luyuan’s solution is to add a remote data transmission module to realize the data interconnection of key electrical components of the vehicle, including the charging and discharging data of the lithium battery. Through the data monitoring platform of the headquarters, we can predict battery failure modes, inform users in advance and provide quick services, and eliminate potential safety hazards in the bud. 2. Safety measures 2: Improve the structure and enhance the safety of lithium batteries Compared with electric bicycles, the use environment of lithium batteries for electric bicycles is more severe. The vehicle has poor shock absorption performance; the riding conditions are complicated; the vehicle is often placed outdoors, and the battery is directly exposed to the outside, experiencing wind, sun, and rain. Lvyuan independently designed a fully sealed, breathable, dry, water-proof and moisture-proof structure. The interior is filled with high thermal conductivity silica gel. While improving the seismic level of the internal battery core and BMS board, it also further enhances the waterproof and moisture-proof performance. At the same time, it achieves the purpose of equalizing the temperature between the cells inside the battery, ensuring the consistency of the cells, and thereby improving the service life of the entire battery. 3. Safety measure 3: Two-way handshake recognition circuit to ensure that the battery is not used indiscriminately. Electric bicycles on the market are basically straight-through output methods, which facilitates the abuse of battery supply by users. If the lithium battery is used in lead-acid vehicles, that is, lead-to-lithium sales; or used as a test treasure for lead-acid vehicle trial riding; there will also be maintenance personnel using lead-acid controllers or chargers to replace faulty lithium battery control And charger. These are the bad habits left by the lead-acid battery era. Once the lithium battery is misused on a lead-acid vehicle, the lead-acid controller has EABS reverse charging and is inconsistent with the undervoltage point of the lithium battery, which will cause safety hazards to the lithium battery. Luyuan’s countermeasure is to add a two-way handshake recognition circuit between the lithium battery BMS board and the controller, and before the BMS board and the charger. As long as they do not match each other, the lithium battery will close the charging and discharging circuit, and illegal control is not allowed. Discharging the charger and charging illegal chargers to reduce safety accidents of lithium batteries caused by external factors. 4. Lithium battery safety measures 4: PGR motor alert Lithium battery reverse charging EABS reverse charging is a very good point of interest for lead-acid batteries, but for lithium batteries, it has become a safety hazard.
