Brief analysis of the balance principle of lithium battery protection board

Is the lithium battery pack balance protection board good? The lithium battery protection board balance principle is the lithium battery balance board good? The lithium battery maintenance board balance principle. A large number of lithium battery maintenance board manufacturers mentioned the introduction of the balance function, which plays an important role in the battery system. The lithium battery maintenance board is a useful way to extend battery life and gradually attract our attention. At the same time, lithium batteries The key use of the maintenance board balance system has also attracted widespread attention. Regarding the lithium battery system with multiple series balancing, there are two traditional passive balancing and automatic balancing methods. Whether the lithium battery pack maintenance board has a balance function is controversial. The following are the opinions of lithium battery manufacturers. 1. It is necessary to adopt a balanced situation: it takes longer to complete the deposit in the lithium battery processing, because people keep the static power consumption of the board and the self-discharge rate of various batteries is different, forming the entire bundle, and the battery voltage has a significant pressure difference. However, the balanced voltage function of the balanced lithium battery pack under the condition of ensuring consistent capacity can achieve the battery capacity of fully charged and fully discharged, which maximizes the result of the battery. 2. The state of balance does not work: Many people think that the balance of lithium battery packs works in the middle and later stages. The actual battery packs used in the middle and later stages cause a poor capacity due to different battery capacity losses. The balance is not compensated by the maintenance board. The capacity of the battery, so we should know the balance voltage, capacity and not to make up for the lithium battery maintenance board. In the 13 series of lithium battery packs, it is recommended not to use the balancing function, but it is necessary to strictly close the battery pack to try to achieve the consistency of battery capacity and internal resistance. Lithium batteries are afraid of storage, not afraid of use! Lithium batteries are suitable for single storage, not for overall storage. The battery pack should be tested as soon as possible in the hands of consumers. When charging lithium batteries in series, it is necessary to ensure that the charge balance of each battery, otherwise it will affect the performance and life of the entire battery. Commonly used equalization charging techniques include: constant shunt resistance equalization charging, switching shunt resistance equalization charging, average battery voltage equalization charging, switched capacitor equalization charging, buck converter equalization charging, inductance equalization charging, etc. During the charging process of lithium batteries, each lithium battery has a balancing circuit. When charging, the voltage of each battery is controlled by the balance circuit of the lithium battery maintenance board, so that each battery is in the same state to ensure the performance and life of the lithium battery. According to the balance principle of the lithium battery maintenance board, the lithium battery monolithic maintenance chip of the control circuit can be selected according to the voltage level of the lithium battery to be maintained and the maintenance delay time. Parallel discharge branch resistance can be completed by power resistance or resistance network. The maintenance subsystem model of the lithium battery maintenance board is important to simulate the timing and logic of maintenance actions through logic operation modules, symbolic function modules, one-dimensional look-up modules, integration modules, delay modules, switch modules, and mathematical operation modules. Since the simulation environment is different from the actual circuit, do not perform filtering and strong and weak current isolation during the simulation. The remaining modules often lead to a longer simulation time. According to the balance principle of lithium battery maintenance, after changing the maintenance chip model and number, the maintenance of power and charging lithium battery packs with any structure and voltage level can be completed in the power component circuits of switch equipment and energy consumption. Conclusion: The lithium battery maintenance board has the function of maintaining the battery and preventing the battery from overcharging. The balance lithium battery has the function of balancing the voltage, so as to achieve the full charge of the battery capacity, give full play to the function, and make the battery perform the best.
