Working principle of warm air _ pure electric vehicle

New energy heating can be divided into two ways, one is water heating PTC, and the other is wind heating PTC. In the way of water heating, high-voltage direct current is distributed to PTC through the distributor, and when PTC is electrified, it generates heat, heats the coolant and circulates it to the warm air water tank. The heater dissipates heat through the fan and realizes water circulation through the electronic water pump. Its structure is similar to engine heat collection. The way to heat the air is simpler. The high-voltage heating resistance wire is installed in the original position of the warm air tank, which generates heat after being electrified and blows out hot air through the fan. Both methods require high-voltage battery packs to provide electric energy to generate heat sources.
