Abstract

A computer system (122) for thermal runway detection in an electrical energy storage device (102) comprising: a high voltage electrical energy storage device (102), a low voltage electrical energy storage device (104), thermal runaway detection sensors (1061, 106n) configured to detect thermal runaway events in cells or modules of the high voltage electrical energy storage device, the low voltage electrical energy storage (104) supplying power to the thermal runaway detection sensors (106) via a first power supply line (108), a first switch (110) in the first power supply line (108) between the low voltage electrical energy storage device and the thermal runaway detection sensors, a second switch (114) in a power supply line between the high voltage electrical energy storage device and the thermal runaway detection sensors, the computer system comprising processing circuitry (120) configured to: in response to a first condition, open the second switch (114) and engage the first switch (110), whereby the thermal runaway detection sensors (106) are powered by the low voltage electrical energy storage device (104), and in response to a second condition, open the first switch (110) and engage the second switch (114), whereby the thermal runaway detection sensors are powered by the high voltage electrical energy storage device (102).
