BATTERY CAR PERFORMANCE SURVEY
Many references to electric cars do not include their ranges, cruising speeds and battery fractions (the ratio of battery weight to gross vehicle weight). The author includes data on the performance of three British cars in a discussion of the implications of the recent worldwide survey. Scatter diagrams are plotted of the maximum speeds and cruising speeds against motor power, and range is plotted against battery fraction. Cars are classified into three groups by weight: those over 1.2 tonne, 1.0 to 1.2 tonne and under 1.0 tonne. Curves derived from the data show that the range could be up to 220 km at 45 km/h or 137 km at 88 km/h for a 45 percent battery fraction. It is surmised that a lead-acid battery car, when available, would weigh between 1.0 and 1.2 tonnes, it could possibly have a maximum speed of 80 km/h and cruise at 60 km/h. It might have a range of about 80 km using a 6-10 kw/tonne motor and a battery fraction of 35 percent. (TRRL)
