1. A battery pack monitoring system, comprising:
a battery pack monitoring controller, comprising:
a memory; and
a processor coupled to the memory;
a voltage sensor coupled to the processor and configured to measure a voltage of a monitored battery pack residing within a battery energy storage system that comprises a plurality of battery packs;
an ambient temperature sensor coupled to the processor and configured to measure an ambient temperature of the monitored battery pack;
an electric current sensor coupled to the processor and configured to measure an electric current of the monitored battery pack;
a cell voltage sensor coupled to the processor and configured to measure a voltage of a battery cell of the monitored battery pack; and
a cell temperature sensor coupled to the processor and configured to measure a temperature of a battery cell of the monitored battery pack,
wherein the measured voltages, the measured temperatures, and the measured electric current are stored in the memory of the battery pack monitoring controller, and wherein the monitoring system is configured to monitor a subset of the plurality of battery packs of the battery energy storage system that comprises more than one battery pack and fewer than all battery packs of the plurality of battery packs.
