Due to the rapid development of power lithium batteries in recent years, there have been considerable breakthroughs in production technology, material technology improvements, or price advantages, so it has also laid a solid foundation for multiple parallels. The era of replacing lead-acid batteries is getting closer. Regardless of whether electric bicycles or backup power supplies, its market share has naturally begun to expand wildly, which is an undeniable fact. Then, for the safety and life of the battery, the effective protection of the lithium battery is naturally indispensable. At this time, the protection plate is also one of the very core components in the battery pack.
Theoretically speaking, the power multi-string battery protection board does not have much electronic technology content, such as circuit and software processing, there are too many choices. The main thing is how to make the protection part stable, reliable, safer and more practical. Of course, the price is also one of them. If you really want to do it well, it is a very complicated, careful and long cycle of work. According to the ratio of experience to technical value, technology only accounts for 20%. Experience should account for 80%. It is still difficult to do a good job of power battery protection board without three or five years of experience. Of course doing it well and being able to do it are two different things. Why is there such a conclusion? There is evidence. To be honest, the circuit of the protection board is not complicated. As long as you have worked in the battery electronics industry for one or two years, it is not difficult to design a circuit and copy someone else's circuit. For example, multi-string power batteries mainly work with high voltage, high current, high internal resistance (micro current), and consideration of the working environment of the battery pack, etc., which all involve years of comprehensive experience in electronics. As big as the understanding of the entire PACK, as small as the selection of a resistor, capacitor or transistor, or the attention to detail when laying out the board. In a word, the protection board is mainly to protect the battery pack in a stable, reliable and safe way, to ensure the normal and safe use of the battery pack or to use it for a longer time. Other added unique technologies and functions are all clouds.
