Due to the rapid development of power lithium batteries in recent years, there have been considerable breakthroughs in production process, material technology improvement, or price advantages. Therefore, it also lays a solid foundation for many parallel and many series batteries. The era of replacing lead-acid batteries is approaching. Whether electric bicycle or backup power supply, its market share naturally began to expand wildly, which is an undeniable fact. Then, for the safety and service life of the battery, the effective protection of lithium battery is also indispensable. At this time, the protection board is also one of the very core components in the battery pack.
Theoretically, the power multi string battery protection board does not have much electronic technology, such as circuit and software processing, and there are too many choices. It is mainly about 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 complex, careful and long cycle work. If the ratio of experience to technical value is to be considered, technology only accounts for 20%. Experience accounts for 80%. It is difficult to do a good job of power battery protection board without three or five years of experience. Of course, doing well and being able to do are two different things. Why is there such a conclusion? This is well founded. To tell the truth, the circuit of the protection board is not complex. 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 another circuit. For example, multi string power batteries mainly work with high voltage, high current and high internal resistance (micro current), consider the working environment of battery pack, etc., which involve many years of comprehensive experience in electronics. As big as the understanding of the whole pack, as small as the selection of a resistor, capacitor or transistor, or the attention to details when distributing boards. In a word, the protection board mainly protects the battery pack stably, reliably and safely to ensure the normal and safe use or longer use of the battery pack. Other added unique technologies and functions are floating clouds.
