Low temperature preheating techniques for Lithium-ion batteries:
Therefore, Z. Qu [99] evolved the DC preheating technology by indirectly applying DC excitation, thus enabling battery preheating. Compared with continuous DC preheating, the battery can be heated up from −10 °C to 10 °C within 175 s while the DC preheating consumes 280 s with approximating polarization voltage.

6 FAQs about [How much battery preheating power]
How much power does a battery heater use?
Since pre-heating only goes on for 20-30 min and a good amount of energy is needed to heat the cabin, you get an idea how much is left to heat the battery. The battery heater itself has a max power of 6 kW. So even if it would run at full power for one hour, it would not be able to heat the battery to a level where it has zero regen limit.
How much energy does it take to heat a car battery?
But it would require about 8.5 kWh to heat the battery from 10 to 25 degree Celsius. That's almost one full hour of full power charging with a single charger. Since pre-heating only goes on for 20-30 min and a good amount of energy is needed to heat the cabin, you get an idea how much is left to heat the battery.
Is pre-heating a battery a good idea?
Pre-heating the battery will have no advantage unless it gets a lot colder as the amount of battery used will be greater than the range advantage and the battery heats up as its used. Thanks for the insight. I wonder how much battery percentage drops for that 10 minutes cabin heating before the journey. It would be ideal if i start with a 100% SOC.
Should I pre-heat my car battery?
Pre-heating the battery will have no advantage unless it gets a lot colder as the amount of battery used will be greater than the range advantage and the battery heats up as its used. The pre-heat of the cabin might not work if the car is plugged in but not charging so you might have to nip out and disconnect the charger.
