These methods can be broadly categorized into four types: passive cell balancing, active cell balancing using capacitors, Lossless Balancing, and Redox Shuttle. Each Cell Balancing Technique approaches cell voltage and state of charge (SOC) equalization differently. Dig into the types of Battery balancing methods and learn their comparison!
In the domain of Battery Management Systems (BMS), there are two types of Cell Balancing techniques available. Let's get on them one by one. In an active cell balancer, energy transfers from a higher voltage to a lower voltage cell within the battery. In other words, the cell with higher SoC transfers energy to a lower SoC cell.
Battery Cell Balancing also means battery redistribution to improve the overall potential of the battery pack and emphasize each cell's longevity. Cell Balancing enhances the State of Charge (SOC) of your battery. An imbalance is created when every cell in the connected series of the battery pack depicts a different SOC.
By identifying and mitigating unsafe operating conditions, the BMS ensures the safe operation of the battery pack and the connected device. It prevents overcharging, over discharging, and thermal runaway. To maintain uniformity across individual cells, the BMS incorporates a cell balancing function.
This battery balancing method uses resistors in a balancing circuit that equalizes the voltage of each cell by the dissipation of energy from higher cell voltage and formulates the entire cell voltages equivalent to the lowest cell voltage. This technique can be classified as a fixed shunt resistor and switching shunt resistor method.
It consists of accurate control strategies, careful design, strong safety mechanisms, and complete diagnostics and maintenance methods. Flawless integration is a must as it ensures that the balancing methods work effectively within the BMS, optimizing the battery pack's performance, improving protection, and expanding its life.

Your external power supply - is it a power supply or a battery charger? If it is a power supply your device would have no function with out it, so it would have to be considered as part of the device. Perhaps even, it might not perform it's medical purpose whilst charging.
If labeling, promotional materials, or other evidence of intended use demonstrates that the device is intended to support, supplement, and/or augment another device, whether a particular brand or a device type, that device is considered an accessory. For example, an infusion pump system may include an infusion pump and a stand.
IV. Definitions Accessory: A finished device that is intended to support, supplement, and/or augment the performance of one or more parent devices.
Definitions Accessory: A finished device that is intended to support, supplement, and/or augment the performance of one or more parent devices. Component (21 CFR 820.3(c)): “ny raw material, substance, piece, part, software, firmware, labeling, or assembly which is intended to be included as part of the finished, packaged, and labeled device.”
The battery example is now absent from the final guidance, and the final guidance states: “non-device-specific off-the-shelf replacement parts (e.g., batteries, USB cables, computer mouse, etc.) may be used with a medical device, but FDA does not intend to consider these products to be accessories or medical devices.”
It is important to note that articles that do not meet the definition of an accessory will not be treated as accessories simply because they may be used in conjunction with a device. For example, a mobile smart phone would not be considered an accessory after having downloaded a medical application (app).
Although analyzing data from a device would not result in the software being deemed an accessory, the guidance states that software that may be used in combination with other devices may be considered an accessory.
