Every home-HVAC heat pump I've ever seen has had supplemental and/or "emergency" heat. They all had resistive electric supplemental heat. I've read more recently about HVAC systems that use fuel gas heat as the supplement. I'd assume (and we all know what that is!) that all production EV heat pumps would also include resistive heating. Very few people will tolerate Yugo- class heating in their vehicles. (The infamous Yugo GV ICEV came with a pitiful heater. Owners who complained were told to keep the blower on LOW position so the air coming out of the vents would feel a little warmer.) IMO fitting a heat pump to a conversion EV is going to be a pretty significant challenge. That holds whether you're trying to make a HP from an existing aircon that came with the ICEV you're converting, or trying to convince a HP system from a production EV that it should work in a vehicle with none of the Canbus signals it expects. I would have no idea where to start.
