The electric vehicle charger thermistor generally uses 1.3KΩ~3.3KΩ, the larger the resistance, the more current is needed, the easier it is to generate heat; A smaller resistance requires less current and less heat. Usually, even under the highest load conditions, the electric vehicle charger thermistor can still choose 1.5KΩ~3KΩ. Secondly, the resistance value in general, the resistance value of the electric vehicle charger thermistor depends on the charging voltage of the electric vehicle,

In general, the resistance value of the 24V charger thermistor should be 2-10 ohms, the resistance value of the 48V charger thermistor is 4-20 ohms, the resistance value of the 72V charger thermistor should be 6-30 ohms, and the resistance value of the electric vehicle charger above 96V thermistor needs to be larger, which can reach 12-60 ohms.
