NTC thermistors for EV Batteries

NTC thermistors are placed within the battery pack to continuously monitor the temperature of the battery cells. They detect any temperature fluctuations, including rises or falls, that could impact battery performance or safety. The BMS uses the temperature data from the NTC thermistors to make decisions about charging and discharging. For example, if the battery temperature is too high, the BMS may reduce charging power or even halt charging to prevent overheating. Similarly, if the temperature is too low, the BMS may adjust charging or discharging parameters to optimize battery performance.

Role of NTC Temperature sensors in EV Battery

Safety : Temperature monitoring is crucial for preventing thermal runaway, a dangerous situation where battery cells overheat and potentially cause fire.

Performance : Maintaining the battery within its optimal temperature range ensures efficient operation and maximizes the EV's range and charging speed.

Longevity : Extreme temperature fluctuations can shorten the lifespan of battery cells, so proper temperature management is important for overall battery health.
