Abstract:
In an embodiment, a system includes a battery management unit (BMU) (14) coupled to a battery pack (12) of an xEV (10). Further, the BMU 14 is configured to determine an energy remaining value (122) for the battery pack (12) based, at least in part, on a minimum cell temperature (104) and a minimum cell state of charge percentage (SOC%) (106) determined by the BMU (12) for the battery pack (14).
Abstract:
Provided herein is an electrode active material comprising a lithium metal oxide and an overcharge protection additive having an operating voltage higher than the operating voltage of the lithium metal oxide.
