Battery pack charge cell balancing

This invention describes a system for charging a series of lithium-ion battery cells, specifically those made of LFP, NMC, or NCA materials. It uses two separate electrical paths from a power source to the batteries. One path delivers power at a certain voltage, while the other path includes a voltage-reducing component called a buck converter to supply power at a lower voltage.

Why it matters: The classification highlights data exchange for battery management. Since 2022, the integration of advanced battery management systems (BMS) with sophisticated data processing has become more prevalent, making complex charging strategies that optimize cell health and efficiency more feasible and valuable.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateElectronic circuit design, power management, buck converter.
