Potential safety hazards of new energy electric vehicle charging

During the charging process of new energy electric vehicles, due to the large charging current, especially when the charging current is large, the temperature of the charging gun will rise, and the shell of the charging gun will expand due to heat, making it difficult to remove the charging gun from the charging socket after charging. There will also be safety hazards.

Difference between NTC and PTC

The thermistor is an electronic component whose resistance value changes with temperature. Within the operating temperature range, its resistance value decreases with increasing temperature/increases with declining temperature. Conversely, its resistance value rises with the rise of temperature / decreases with the decline of temperature, referred to as a PTC thermistor.

Working theory of NTC thermistor / What is NTC thermistor

NTC (Negative Temperature Coefficient) refers to the thermistor phenomenon and material with a negative temperature coefficient whose resistance decreases exponentially with temperature rise. The material is a semiconductor ceramic made by fully mixing, molding, and sintering two or more metal oxides such as manganese,
