AI Technical Summary

Benefits of technology

This technology allows multiple cells (B) inside one unit cell phone or other electronic device to work together optimally without overheating them due to their own characteristics such as temperature sensitivity and self-discharging ability. It also helps maintain optimal operation conditions while reducing damage from excessive voltages that could cause electrical failure within these devices. Additionally, this technology makes it possible to use different types of energy sources like lithium ion batteries with varying capacities depending on how much electricity they require at once. Overall, this innovation enhances the overall efficiency and longevity of rechargeable batteries used in various applications including mobile phones, laptops, cameras, medical equipment, automobiles, airplanes, space exploration tools, military systems, among others.

Problems solved by technology

Technological Problem: Current methods used for controllably adjusting the balance between charged voltages (volts) inside individual cells during recharge are unreliable due to variations in cell structures or characteristics from previous cycles. Additionally, these techniques may result in changes affecting the performance of the entire system if they don't work properly at all times.

Embodiment Construction

[0014] refer to figure 1 , The storage battery online balancing system of the present invention includes a central processing controller 1, a power collection module 2, a battery switching module 3, a voltage online balancing module 4, and an internal resistance capacity online balancing module 5 and the like.

[0015] The central processing controller 1 can be implemented by using an ARM processing chip, such as a chip with a model number of STM32F103VBT6, which can well meet the requirements of the present invention. The power acquisition module 2 collects the power parameters of the battery pack and a single battery in the battery pack, and the power parameters are sent to the central processing controller 1. The ARM processing chip generally has an analog-to-digital conversion module, which can be well integrated with power collection. The module 2 is used together to realize the conversion process of various collected electricity. The electricity detected by the electricity
