NF 8KW AC430V PTC Coolant heater for EV

Short Description:

PTC coolant heater For purely electric vehicles, the battery is a high voltage battery and the electric heater is generally chosen to be high voltage because the voltage is high and the same electrical energy can be converted into heat more often.

Depending on how the electric heater works it can also be divided into those that heat the air(PTC air heater) directly and those that heat the air indirectly by heating water. The direct heating of air is based on the same principle as an electric hairdryer, while the water heating type is closer to the form of a heater. This time we present and demonstrate electric heated water heaters.

For traditional fuel vehicles, the air conditioning mechanism usually relies on the heat emitted from the engine to provide heating for the interior of the vehicle. For NEV vehicles, as there is no engine component or pure electric driving mode, it is not possible to rely on the engine running to meet the heating demand in actual driving, so NEV vehicles need to add additional heat generating equipment, and the current common heating method is PTC (Positive Temperature Coefficient) heating system.

This time we present and demonstrate electric heated water heaters.
