BATTERY CHARGE AND DISCHARGE CONTROLLER

摘要

Methods, systems, and devices are described for described for providing control circuitry for use with battery packs. Embodiments optimize charging and discharging cycles to mitigate overcharging, over-discharging, and/or overheating individual cells in a battery pack. For example, embodiments allow for full discharging of battery packs (i.e., bringing the battery pack and its individual cells closer to their minimum voltages without going below) and full charging of battery packs (i.e., charging each cell of the battery pack closer to their maximum voltages without exceeding). Further, some embodiments include a substantially lossless, bi-directional DC-to-DC converter for facilitating ultra-fast charging of battery packs (e.g., at greater than 10C charge rates) without overheating or overcharging the individual cells of the battery packs.
