What are the important uses of lithium battery protection board?

The important use of lithium battery protection board? 1. Charging is balanced from time to time. It is mainly used when the voltage of any battery is higher than the average voltage of all batteries during charging. No matter what the size of the battery voltage, it is mainly applied to the smart software plan. Of course, the definition can be adjusted arbitrarily by the software. The advantage of this plan is that it has more time to balance the battery voltage. Second, the voltage fixed-point equalization is to set the equalization start at a voltage point, such as manganese-lithium batteries, many of which are set to start equalization at 4.2V. This method is only performed at the end of battery charging, so the equalization time is shorter and the use can be imagined. Third, static automatic equalization. It can also be carried out during charging and discharging. What is more distinctive is that when the battery is placed in a static state, if the voltage is not the same, it is also equalizing until the battery's The voltage reaches common. But some people think that the battery is out of work, why the maintenance board is still heating? The above three methods are based on the reference voltage to achieve balance. However, high battery voltage does not necessarily mean high capacity, it may be the opposite. The following argument. Its advantages are low cost, simple planning, and it can play a certain purpose when the battery voltage is different, which is mainly reflected in the voltage difference caused by the self-consumption of the battery for a long time. In theory, there is a weak feasibility. Defects, messy circuits, many components, high temperature, poor anti-static, high failure rate. The detailed discussion is as follows. B energy transfer balance, which allows large-capacity batteries to be transferred to small-capacity batteries by means of energy storage. It sounds very smart and practical. It also divides capacity from time to time balance and capacity fixed-point balance. It is balanced by detecting the capacity of the battery, but it does not seem to take the voltage of the battery into consideration. Think about it, take a 10AH battery pack as an example. If there is a battery pack with a capacity of 10.1AH and a smaller capacity at 9.8AH, the charging current is 2A, and the energy balance current is 0.5A. At this time, the 10.1AH battery needs to be charged with a small capacity of 9.8AH. The charging current of the 9.8AH battery is 2A+0.5Au003d2.5A. At this time, the charging current of the 9.8AH battery is 2.5A. At this time, 9.8AH The capacity of the 9.8AH battery has been replenished, but what is the voltage of the 9.8AH battery? Obviously it will rise faster than other batteries. If the charging end is reached, the 9.8AH battery will definitely be overcharged and maintained much in advance. During the discharge cycle, small-capacity batteries have always been in a state of deep charge and deep discharge. Whether other batteries are fully charged is not sure if there are too many elements. The weak and intuitive ones will be analyzed here, too much analysis for fear of incomprehension.
