Battery System Design.12v 100ah deep cycle battery

　　Two separate electronic protections must be provided for overcharging, discharging, and overcurrent. Remove the protective board and charge it. If the battery explodes, it indicates poor design. Remove the protective board and charge it. If the battery explodes, it indicates poor design. Although the above methods provide two protections, consumers often purchase non original chargers to charge after the charger breaks down. Charger manufacturers, based on cost considerations, often remove the charging controller to reduce costs. As a result, Gresham's law drove out good money, and many low-quality chargers appeared on the market. This makes overcharging protection lose its first and most important line of defense. And overcharging is the most important factor causing battery explosions, therefore, low-quality chargers can be called the culprits of battery explosions. Of course, not all battery systems adopt the scheme shown in the above figure. In some cases, there may also be a design of a charging controller within the battery pack.

　　For example, many laptop computers have a charging controller attached to the battery rod. This is because laptop computers generally have a charging controller built into the computer, only providing consumers with an adapter. Therefore, the external battery pack of notebook computers must have a charging controller to ensure the safety of the external battery pack when charging with an adapter. In addition, products that use car cigarette lighters for charging sometimes also have a charging controller installed inside the battery pack.

　　The last line of defense: If all electronic protective measures fail, the last line of defense will be provided by the battery cell. The safety level of battery cells can be roughly distinguished based on whether they can withstand external short circuits and overcharging. Due to the fact that before the battery explodes, if lithium atoms accumulate inside the material surface, the explosion power will be greater. Moreover, the protection against overcharging often leaves only one line of defense due to consumers using inferior chargers. Therefore, the ability of the battery cell to withstand overcharging is more important than the ability to withstand external short circuits. Comparison of safety between aluminum shell battery cells and steel shell battery cells. Aluminum shell has a high safety advantage compared to steel shell battery cells.
