Active balancing protection boards, as a core component of battery management systems, are specifically designed to address inconsistencies among individual cells in a battery pack, such as voltage and capacity differences, thereby improving the overall performance and safety of the battery pack. They have wide applications in various industries, and some specific examples are as follows:

Electric Vehicle Industry:

The range, power performance, and safety of electric vehicles highly depend on the performance of the battery system. Active balancing protection boards play a crucial role in electric vehicles. For example, a leading electric vehicle manufacturer's battery pack consists of numerous individual cells. Due to differences in manufacturing processes and operating environments, the performance of individual cells gradually varies. The active balancing protection board monitors the voltage of each individual cell in real time and transfers energy from high-voltage cells to low-voltage cells during charging, and ensures that each cell performs optimally during discharging, thus effectively improving the energy utilization rate of the battery pack. This not only extends the vehicle's range but also extends the battery pack's lifespan by approximately 30%, significantly reducing user costs.

Energy Storage Power Station Industry:

Energy storage power stations are crucial for stabilizing the power grid and improving the utilization of renewable energy. In energy storage power stations, a large number of batteries are used for energy storage, making battery consistency management particularly important. A large energy storage power station uses active balancing protection boards to manage its lead-acid battery pack. Due to the high self-discharge rate of lead-acid batteries, significant voltage and capacity differences occur between batteries after long-term use. The active balancing protection board precisely monitors and controls each battery module, preventing overcharging during the charging phase and ensuring that each module discharges at the same rate during the discharging phase, thereby improving the charging and discharging efficiency of the entire battery pack by approximately 15%, reducing energy loss, and enhancing the stability and reliability of the energy storage power station.

Portable Electronic Device Industry:

With the popularity of portable electronic devices such as smartphones and tablets, users have higher demands for the battery life and safety of their devices. Active balancing protection boards also play an important role in the battery management of these devices. For example, a well-known brand of smartphone has a built-in lithium-ion battery pack composed of multiple individual cells, and differences between the cells occur during use. The active balancing protection board monitors the status of each individual battery cell in real time, performing dynamic balancing adjustments to ensure that each battery is fully charged during charging and to prevent overcharging. During use, it intelligently distributes output power, extending battery life. It also features protection functions against overcurrent, overvoltage, and short circuits, effectively improving the safety of the mobile phone battery. By using an active balancing protection board, this brand of smartphone has extended battery life by approximately 10%, significantly improving the user experience.

Other industries:

In addition to the industries mentioned above, active balancing protection boards are also widely used in drones, power tools, electric bicycles, and other fields. In these applications, the active balancing protection board also improves the performance and lifespan of battery packs by addressing battery inconsistencies, enhancing the safety and reliability of the equipment, and providing strong support for the development of various industries.
