Between 100 kg to 544 kg is the weight of an electric car’s battery. It depends on its kWh energy capacity and other factors like energy density. In general, the battery weighs more the farther it can travel.
Although they lack a combustion engine, electric automobiles have an electric motor and a battery instead of a gas tank.
Although different technologies have been utilized in hybrid vehicles and research is currently underway for future ones in electric cars, batteries are typically lithium-ion.
And sure, the weight of the batteries for electric cars is relatively high, as you may have thought.
The multi-energy versions, or those that come with both an internal combustion engine and an electric version, are particularly conspicuous for their weight.
In addition to implying a significant weight variation, adding a lithium-ion battery modifies the weight distribution and, as a result, the dynamic behavior.
But getting back to the question: how much does an electric car’s battery weigh?
Battery weight in electric vehicles
Even though the weight of an electric car battery is typically inversely correlated with its kWh energy capacity, the truth is that this direct correlation is not always determined by the energy density and other factors, such as the cooling system, the “circuitry,” or, for instance, the packaging of the battery modules.
This explains some significant variations across devices with the same or almost identical energy capacities.
Models with 6 to 12.5 kWh battery packs weigh about 100 to 150 kg for this component; choices with more excellent range, however, have a battery weight of about 380 to 550 kg with a 60 to 100 kWh energy capacity.
A Tesla Model S with an 85 kWh battery, for example, owes 544 kg of its weight to the lithium-ion battery; a Renault Zoe, on the other hand, owes 290 kilograms.
This specific type is also odd because the same Renault Zoe, which has a 41 kWh battery, weighs 305 kg. It delivers a much bigger battery capacity and more autonomy for just 15 kilograms.
For manufacturers, this information—the weight of the battery in electric vehicles—is crucial. The range is more extensive the lower the overall weight is.
This factor, like aerodynamics, is given as much consideration as possible when it comes to electric cars.
