Page 7: Battery System Sizing
Consider these three parameters when determining the size of the battery system. Battery Rated Energy • Golf carts can travel from 4 to 8 miles per kWh. One EX-GC2-48036 battery has a rated energy of 1.8kWh, so the equivalent range per battery is 7.2 to 14.4 miles. Assume: One EX-GC2-48036 battery can provide 10 miles of drivable distance You plan to play an 18-hole course N times (N = 1, 2, 3, …) - Page 8 Round up the maximum number of Number_of_batteries_1,2,3 to be the number of batteries for the battery system. E.g.: Number_of_batteries_1 = 3.20 Number_of_batteries_2 = 3.63 Number_of_batteries_3 = 3.40 The number of EX-GC2-48036 batteries for this installation is 4.
