Heterogeneous Battery Cell Charging

摘要

Heterogeneous battery cell charging techniques are described for a device having a battery system with heterogeneous battery cells. A control system is provided that is configured to determine a charging strategy for charging the heterogeneous battery cells based upon an analysis of a plurality of contextual factors. For example, contextual factors may indicate anticipated future load conditions, battery usage preferences established for the battery system, and/or other factors indicative of an overall context in which charging occurs. Different charging strategies that indicate which battery cells to charge and the way in which charging is to be conducted may be mapped to different combinations of the contextual factors such that the charging is dynamically tailored to different contexts. A selected charging strategy is then employed to distribute charging current from a power source among the heterogeneous battery cells in the manner designated by the selected charging strategy.
