Enow Solar Test Results: Winter, Spring And Summer Battery APU Operation
ENOW SOLAR TEST RESULTS: WINTER, SPRING AND SUMMER BATTERY APU OPERATION Summary Results eNow Inc. has been collecting data from three Class 8 Sleeper Trucks equipped with Battery APU systems. Two of the trucks are equipped with a Solar Battery Charging system – one is a 200 Watt (rated) system sold by a competitor and the other is a 300 Watt (rated) system sold by eNow Inc. The third truck is a “control” truck, which is not equipped with solar. Based on the data collected during this period, we can conclude: - Battery APU A/C use was very low initially (Jan-Mar), but, as expected, Battery APU A/C use increased in the spring and summer (Apr-July). - Overall, solar maintained a higher average voltage (i.e., higher state of charge) for both the truck and auxiliary batteries over the
