Volumetric Energy Density Calculation

Volumetric energy density (VED) is a measurement of the amount of energy (capacity, kWh) that can be stored in a given volume.  A higher number means more kWh in a smaller battery box. EVDrive battery modules have the highest VED available.

• VED equals capacity divided by volume. For EV batteries VED is measured in Watt hours per liter (Wh/l). VED can be calculated from the capacity in kilowatt hours (kWh) and the dimensions of the battery box in millimeters with the following formula:
• VED = kWh X 1,000,000,000 divided by the height X width X length of the pack in mm.
• For example, a 60 kWh 12X28, 10 module pack has dimensions of 288 X 721 X 941 mm (see example).
• VED = 60 X 1,000,000,000/(288 X 721 X 941) = 307 Wh/l

Use this formula to compare the VED of EVDrive batteries with others available on the market.
