What is battery preheating
[WapCar] Battery preheating refers to a technology used to enhance the battery temperature as soon as possible when "starting" the new engine vehicles, especially the pure electric vehicles, so that it can enter the optimal working temperature.
Pre conditioning
The high voltage battery is what needs preheating (sometimes). The HV battery power is sent to the rear motor in such a way as to create nothing but heat in that motor (rather than motion), which is then carried away (and to the high voltage battery) by the coolant which thereby heats the HV battery.
