AI Customer ServiceThe pack Battery Management System monitors voltage, current, and temperature of cells Sensors that should be considered within the EV battery pack design and module assembly systems: 1. Temperature Temperature sensors are critical for electric vehicle battery and cell connection system applications.
In addition, if there are any issues with a battery cell, temperature sensors can provide critical safety data to the BMS, which can immediately notify the vehicle’s owner if the pack is in an unsafe state. Like the battery itself, an EV’s cell connection system is not immune to the effects of excessive heat.
Temperature sensors are critical for electric vehicle battery and cell connection system applications. Put simply, both parts of an EV require constant thermal management for optimal performance and vehicle occupant safety. The need for temperature monitoring for electric vehicle batteries is two-fold:
Research is ongoing to put sensors inside the battery cell, thus giving the ability to measure key internal variables such as electrode potentials, current, temperature, mechanical stress and internal pressure. You do need to consider redundancy as a single thermistor is very cheap as a part, but could be very expensive to replace.
Some of these temperatures are hard limits for the continued safe operation of the cell. For most cells they will operate best between 15°C and 35°C. Jinasena et al break the sensing down into Hard and Soft Sensors. Using this as an initial list we can extend this further into a more complete list of sensors:
