Total number of data points recorded by the power analyser for a given test or total number of cycle repeats in a given test P TMS Instantaneous amperage reading from load ‘x’, A n In the winter months, many differences between the drive cycles were not discernible due to the high cabin conditioning energy consumptions.ĭistance travelled in a charge depleting test repeat i during which the vehicle was propelled solely by the traction battery energy, km E 12VĮnergy draw measured at the auxillary battery terminals leading to the 12 V accessory inverter, Wh E batteryĮnergy discharge measured at main traction battery terminals, Wh ECdc cycleīattery energy consumption for a specific cycle, DC kWh Edc TMS cycleĬabin conditioning energy consumed during a specific cycle, DC kWh Edc x Summer city and highway driving resulted in the lowest energy consumption (Wh/km), while congested and expressway driving cycles resulted in the highest. On average, heating the cabin in the winter months consumed significantly more electric energy than cooling the cabin in the summer months. Cabin conditioning energy was found to be directly related to the difference between ambient and cabin temperature, except at low temperatures (< 0 ☌) when the 1.4 L engine activates to assist the thermal management system. ![]() At 25 ☌ the Chevrolet Volt’s on-road all-electric EPA-method adjusted range is generally less than the U.S. Results from these studies were analysed to evaluate the overall performance of the Chevrolet Volt on public roads in climates representative of most of Canada (-27 ☌ to 37 ☌) using realistic accessory settings. Both NRCan and EC tests measured cumulative electrically driven distance (all-electric range), select CANbus signals and AC grid supply charge energy. ![]() EC tests recorded cabin conditioning, traction battery and 12 V accessory power, select vehicle component temperatures, regulated emission rates and exhaust flow, and DC charge energy. More than 1300 trips were conducted over nine routes: three city, one congested, two arterial, one highway and two expressway routes. ![]() Environment Canada (EC) and Natural Resources Canada (NRCan) separately tested two 2012 Chevrolet Volts between 20 in Ottawa, Ontario on public roads in the summer and winter months using realistic cabin-climate control settings.
