6 FAQs about [Device for measuring low temperature batteries]
Does a temperature measurement provide a specific location in a battery system?
In the existing literature, many temperature measurements or SOT estimations only provide temperature information at some specific locations in the battery system (e.g., battery surface or core).
How do you measure the temperature of a battery?
The most direct approach is to measure the battery temperature via various measurement devices such as thermistors and thermocouples [, , ]. These temperature sensors can be placed at the battery surface to measure the surface temperature during operations [48, 51].
