Abstract: A system includes data processing hardware and memory hardware. The memory hardware is in communication with the data processing hardware and stores instructions that when executed on the data processing hardware cause the data processing hardware to perform certain operations. The operations include receiving a temperature corresponding to a battery, and determining whether the temperature is greater than a predetermined threshold temperature. The operations also include, when the temperature is greater than the predetermined threshold temperature, actuating an ejector to eject the battery from a power supply assembly.
