Nissan leaf heat pump vs. resistance heater: which is the smartest choice for your ev?

When it comes to electric cars, one of the most important factors to consider is how they will perform in cold weather. This is because electric cars rely on their batteries to power everything from the motor to the climate control system. In cold weather, the battery’s capacity can be reduced by as much as 20%, which can significantly reduce the car’s range.

One way to mitigate this loss of range is to use a heat pump instead of a resistance heater to warm the car’s interior. Heat pumps are more efficient than resistance heaters, so they can use less energy to achieve the same level of warmth. This can help to extend the car’s range in cold weather.

How Do Heat Pumps Work?

Heat pumps work by transferring heat from one place to another. In the case of a car’s heat pump, the heat is transferred from the outside air to the inside of the car. This is done using a refrigerant, which is a liquid that can easily change from a liquid to a gas and back again.

The refrigerant is circulated through a series of coils, which are located in the car’s evaporator and condenser. The evaporator is located in the passenger compartment, while the condenser is located outside the car.

When the refrigerant passes through the evaporator, it absorbs heat from the air in the passenger compartment. This causes the refrigerant to turn into a gas. The gas then travels to the condenser, where it releases the heat to the outside air. This causes the refrigerant to turn back into a liquid.

The cycle then repeats itself, with the refrigerant continuing to circulate through the evaporator and condenser until the desired temperature is reached.

How Do Resistance Heaters Work?

Resistance heaters work by passing an electric current through a resistive element. This causes the element to heat up, which in turn heats the air in the car’s interior.

Resistance heaters are less efficient than heat pumps, so they use more energy to achieve the same level of warmth. This can lead to a reduction in the car’s range in cold weather.

Which Is Right for You?

Whether a heat pump or a resistance heater is right for you depends on a number of factors, including the climate where you live, your driving habits, and your budget.

If you live in a cold climate and you drive a lot, a heat pump is a good option because it can help to extend the car’s range. However, if you live in a warm climate or you don’t drive very much, a resistance heater may be a more cost-effective option.

Pros and Cons of Heat Pumps

Pros:

• More efficient than resistance heaters
• Can help to extend the car’s range in cold weather
• Quieter than resistance heaters

Cons:

• More expensive than resistance heaters
• May not be as effective in very cold climates

Pros and Cons of Resistance Heaters

Pros:

• Less expensive than heat pumps
• More effective in very cold climates
• Simpler to repair than heat pumps

Cons:

• Less efficient than heat pumps
• Can reduce the car’s range in cold weather
• Noisier than heat pumps

Other Factors to Consider

In addition to the type of heating system, there are a number of other factors to consider when choosing an electric car for cold weather driving. These include:

• Battery capacity: The larger the battery capacity, the longer the car’s range will be.
• Insulation: Good insulation can help to keep the car’s interior warm, which can reduce the demand on the heating system.
• Tire pressure: Underinflated tires can increase rolling resistance, which can reduce the car’s range.
• Driving habits: Aggressive driving can reduce the car’s range.

The Bottom Line

By considering all of these factors, you can choose the electric car that is right for you and your needs. If you live in a cold climate and you drive a lot, a heat pump is a good option. If you live in a warm climate or you don’t drive very much, a resistance heater may be a more cost-effective option.
