How much does an e-Car's battery weigh?
This depends on the battery type and on its capacity.
The ZEBRA battery installed in our "Lebensland Kärnten" Fiat Panda electric weighs about 160 kg. The Mercedes A Series e-Cell contains 2 lithium-ion accumulator units with a combined power output of 36 kWh. Together, these units clock in at 360 kg. The lithium-ion battery installed in the Renault Fluence Z.E. only weighs 180 kg, with the trade-off being a significantly lower operating range compared to the e-Cell.
Lithium-ion accumulators feature a very high energy density, ranging from 95-190 Wh/kg in current models. This means that they are about three times lighter than lead acid batteries. In addition, with values in the range of 300-1,500 W/kg they exceed the latter's power density as well. The high-powered Tesla Roadster, for example, contains 440 kg worth of modern lithium-ion accumulators.
