This report depicts your daily drive as if you'd been in a particular electric vehicle (which you can change);. The driving recorder in your car recorded the exact motion of your existing vehicle, sends it to EV Profiler's computer center via cellular, the center prepares this report and sends it to you at 7pm every evening.
The program assumes that whatever electric vehicle is selected for simulation was charged up fully overnight, therefore every morning you start out with a 100% charge. From there battery charge is reduced depending on how you drive. There are numerous things you can change to see “what if” scenarios. To do that you must view this report on EV Profiler's web site. The link for every daily report is found in the daily email and on the PDF report itself. Click either link and the interactive report will be displayed. Your password is your cell phone number.
NOTE! – If you drive after 7pm local time that travel will not show up on the emailed daily, report but will show up on the web based interactive daily report later. You may print that report.
| Five Main Areas |
1. Title - Who the DDR was assigned to, day of travel selector and sponsor.
2. Day's Results Bar - The primary (larger); gauge displays the battery remaining after your day's travel and cost comparison between electric and gasoline. The second (smaller); gauge shows the lowest battery level if there was charging at one stop during the day.
3. Map - Where the days travel took place. This links to the power profile.
4. Power Profile - Minute by minute, speed and altitude changes totaled into in how much energy was used for the routes of travel. Shows where the most/least energy was used,
5. Route List - Lists each route of travel during the day and how much battery was used for that route. Shows how long you were parked and allows you to select this location to charge. By checking charge this returns energy to the battery for the duration of park and increases battery gauges.
Days Results Bar
Primary Gauge – This gauge and corresponding percent number, is the reports, and yours, primary result for your days driving. It represents what the selected electric vehicles battery remaining gauge would have indicted had you been driving it, instead of your existing car. This result is the bottom line answer to the “would you have made it” in an electric vehicle. This number is the result of your vehicles second by second driving data and over a dozen other electric vehicle design variables. The formulas are designed to be accurate to within 3%.
Secondary Gauge – The gauge and corresponding percent number represent the lowest battery remaining value you would have seen during the day if you had charged at one parking location during your days travels. To arrive at this number the system picks the spot you parked at longest and assumes you plugged into a level 1 charger. A level 1 charger is simply a normal 120 volt wall outlet. The system adds this charging back into the electric vehicles battery capacity at the rate of about 1,000 watts an hour.
Don't underestimate the value of daytime charging this way. For some electric vehicles this can add back 50% of battery capacity! This extends your useful range 50% and is easy to arrange at many locations.
You can change which parking location(s); you charge at in the Route List
section at the bottom of the report by checking/unchecking the charge box(s);. Summary Data
– This is simply summation of your day's travel. Average speed is over all the travel. Total miles, time and number of routes are self-explanatory. Cumulative altitude changes are the total number of feet your vehicle went up and down. The higher the number the more energy (battery); used. Hilly roads take more energy to travel than flat roads. While regenerative braking recovers some of the energy used going up a hill it's not equal. Operating Costs
– When you began the evaluation the make and model of your existing vehicle was entered into the EV Profiler system. The system then referenced your existing vehicles EPA city and highway mileage ratings. Using a proprietary formula the system estimates the cost of your days travel using gasoline or diesel at local, current prices. The yearly comparison is simply an extrapolation of one days driving. The final summary report offers a averaging of these cost estimates.
These costs do not take into account any maintenance savings of electric vehicles over internal combustion vehicles which are estimated to be substantial. Change Conditions “What If” button
– This is an important link that takes you to the Conditions
page. On the Conditions page you adjust Route Map
– This map displays your vehicles travels for the day. It is used primarily to provide validity of the gathered motion data. The position data on the map is minute by minute though it is recorded in much greater detail. All the stopping points are marked alphabetically on the map. The points link to the Route Power Profile
graph and Route Tables
By placing your cursor over a point on the map or a point on the route power profile graph a star icon will appear on the corresponding point on the map or graph. By moving the cursor from left to right on the route power profile graph a star icon will show your travel on the map! Route Power Profile
– The route power profiles main purpose to show you where the battery energy was used most during you days travel. The main component of the graph is the vertical blue lines. These lines show how many watts of battery energy (actually Watt/Hour/minutes); were used per minute. The more energy used the taller the blue line. The graph also displays the average speed and total altitude change during the minute. By placing your cursor on a blue line the corresponding watts used, altitude and speed are shown on the left hand side for the minute.
This graph best demonstrates how speed and altitude change the vehicles power (battery); use. Route List
– Every route and its approximate ending location are shown in the route list. The duration of every route and the estimated battery used, as a percent of total battery capacity, is listed.
Every route that has a park time of more than one hour has a “charging” box next to it. Initially one of these boxes is checked (See Secondary Gauge above);. This means that for the duration of this park the vehicle was charged at a rate of 1,000 watts per hour. This is approximately equal to a Level 1 charge. This charging wattage is added back to the vehicles battery capacity. This new battery remaining value is displayed on the Secondary Gauge.
