Batteries work based on the principle of a voltage differential and at high temperatures the electrons inside become excited which decreases the difference in voltage between the two sides of the battery.
Electric car heating system.
It greatly improves power consumption when the heater is being used.
The early nissan leafs pre 2013 used resistive heating.
However the chevy volt offers heated driver and front passenger seats and.
In traditional vehicles the engine provides the power for the hvac heating ventilation and air conditioning system.
That s a big disadvantage.
An electric car does things differently because there is no engine and so delivering power to the ac and just about everything else is determined by the amount of stored battery energy.
An electric vehicle is approx 80 energy efficient meaning there is some waste heat available from the power electronics the motor and battery pack.
A heat pump cabin heater has been adopted for heating an electric vehicle ev using less power than conventional models.
Nissan leaf is the first mass produced vehicle in the world to employ a heat pump cabin heater.
Additionally a large matched dynamic fan provides maximum air flow with minimum turbulence and noise gently distributing warmth throughout your space.
In electric cars discharging the battery generates heat.
In production evs most of these parts have a liquid coolant system so cabin heating can be plumbed in exactly like a conventional car heater system and or into climate controlled seats.
In brief cabin warmth on cold days is provided via resistance heating which as you note uses a lot of current.
To help system improvements now underway in fully electric vehicles engineers had to move away from the vehicle s ability to use the large amount of excess heat produced by internal combustion engines.
Electric car drivers now have one more reason to love the summer because in the winter the vehicle s range declines markedly due to the additional energy demanded by the heating system.
In climates where electric cars are or will be a major part of the transportation load from now on consumers demand efficient and powerful heating and cooling in their vehicles.
