This is a summary of your state of charge (SOC) % over the time during the program. Each graph represents about a month of time. Black dots are discharging data, such as, when the vehicle was driving; other dots are charging data where the charging rates are highlighted by different colors.
*Note that for Nissan Leafs, charging type may be unidentifiable from the Geotab device. Certain Nissan Leafs didn't record charging events.
This graph shows your car's efficiency (the boxes) in miles per kWh throughout the EAP compared to that of the entire cohort of similar make and model (the blue line). The y-axis shows you what percentage of the time that specific efficiency was observed for your car. This demonstrates how efficiency varies with driving style and conditions.
The median efficiency for the cohort (all Model 3s) is 3.8 miles per kWh.
This histogram shows the distribution of achievable, or "real range", miles at 100% state of charge for your vehicle's trips during the EAP. It factors in your daily charging and driving habits. This means that if you charge infrequently, vampire (or phantom) drain may make it seem like your real range is lower than if you charged every day.
This data is an extrapolation to 100% SOC based on odometer and SOC data. Trips are defined as data between charging events, so multiple legs of driving data may be combined into one trip. Differences in real range estimates depend on trip efficiency, which varies based on factors such as temperature, speed, road conditions, and vampire drain between trip legs. The y-axis shows the percentage of the trips a specific real range on the x-axis was estimated for your car. The vertical dotted line represents the EPA range of your vehicle, which is an estimate based on a new vehicle under ideal conditions. The vertical solid black line is the median real range value for all your trips.
Note that real range estimates don't take into accout any battery buffer that may supply a little more range after 0% SOC is read on the dashboard. Sometimes the EPA range can include this buffer range.
This plot shows weekly averages of your estimated real range at 100% charge. Recall that the real range used here factors in your daily charging and driving habits. This means that if you charge infrequently, vampire (or phantom) drain may make it seem like your real range is lower than if you charged every day. The left axis and turquoise line show how your real range changed while participating. The right axis and purple bars show the average local temperatures during those drives that we used to estimate your real range. For reference, your vehicle's EPA range is plotted as a horizontal dotted line. The more trips that you took, the better the estimate may be. The temperature didn't change much during the program for most participants during this study.
Note that real range estimates don't take into account any battery buffer that may supply a little more range after 0% SOC is read on the dashboard. Sometimes the EPA range can include this buffer range.
In this graph, your vehicle's real range (the boxes labeled as "My Car") over the entire program is compared to fellow 2019 Model 3s (the line). The number of cohort vehicles is specified at the top of the graph. Since battery capacities and EPA range may vary for the same car model depending on trim, we normalized the real range values, allowing for a wider comparison of your car. Recall that the real range used here factors in your daily charging and driving habits. This means that if you charge infrequently, vampire (or phantom) drain may make it seem like your real range is lower than if you charged every day. The normalization is the ratio of real range to EPA range. The y-axis shows what percent of observations fall in each normalized range.
Note that real rang estimates don't take into account any battery buffer that may supply a little more range after 0% SOC is read on the dashboard. Sometimes the EPA range can include this buffer range.
This histogram shows your estimated current battery capacity. We calculated this by comparing energy outputs (in kWh) from your vehicle's battery to changes in SOC during your trips. This calculation doesn't include any battery buffer capacity. They-axis shows what percent of the time a specific capacity was calculated for your car. The dotted line indicates the gross battery capacity as specified by the manufacturer, including buffers which may not be usable capacity. The black line indicates the median calculated capacity for your vehicle.
Note: Another way to calculate battery capacity is based on how much energy goes into your battery during a charging session.We also looked at this and found that the median capacity from charging is typically within 1-3 kwh of the capacity determined by discharging.
