Lee explains that energy density is power divided by volume. The higher the density, the smaller the volume per given amount of power. This means that Yulon could alter the rather clumsy current design requiring squeezing more than 6000 batteries into the frame of the vehicle. Higher density for any given volume would also allow longer journeys on a single recharge.
李俊忠解釋，能量（電力）除以體積就是能量密度，能量密度愈高，表示體積愈小（可以一改目前一輛車六千多顆電池塞滿底盤的笨重設計）、續航能力也愈高。
