Background

In a scenario where temperature monitoring is required, taking battery temperature monitoring as an example, a lead-wire NTC (Negative Temperature Coefficient ) sensor and a patch NTC sensor may be employed. The lead type NTC sensor is welded at the position of a corresponding bonding pad of the battery circuit board through two leads, and the matchhead is fixed at one corner of the electric core through heat conducting glue for sensing temperature. The patch type NTC is attached to the battery protection plate through an SMT process to sense temperature.
