![]() ![]() That is actually the strategy I used for this trip as my recent driving resulted in far better efficiency than I anticipated on this trip, and the Trend Bars are not available until after driving for a while.Īs I was getting ready to leave, I took a snapshot of my DIC. In many ways, this strategy is similar to how people drive internal combustion vehicles that only have a gas gauge and no projected range display. However, on the side of the coin, if you’ve been driving around town all week and see a projected range of 300 miles, don’t expect to get that much range out of a single battery charge driving at 75 mph. If you get into a Bolt EV on a sunny, 70 degree day and see 150 miles of projected range on a full battery, you’re more than likely going to exceed that. This works both positively and negatively. Each green bar can represent 10 miles or more of driving range, which means that by the time it ticks down to the next green bar, you might have used far more energy than you realized to travel just a few miles.įinally, the Range Estimator isn’t a promise. For electric vehicles with 200 or more miles of range, the 5% increments start to become an issue. ![]() Ultimately, as the driver, you are responsible for knowing where you are going and how you plan to drive there.Īnother key limitation of the Range Estimator is that it doesn’t provide the battery level in 1% increments. It doesn’t sync with Google Maps or a navigation system, so it can’t account for the driving speeds, topography, or weather that you might encounter in the future. One of the biggest limitations people must understand about the Bolt EV’s Range Estimator is that it is not a route planner. Any factors that deviate from the information it currently has access to will affect the accuracy of your projected range. The Range Estimator can only calculate based on recent driving history and current conditions. Yes, the Chevy Bolt EV’s Range Estimator is a powerful tool while taking trips, but it still is limited. Limitations of the Bolt EV's Range Estimator The minimum projected range is very pessimistic, and it tends to fluctuate much less (and to a much lesser degree) than the average and maximum projected ranges. If the Trend Bars are not present, the Range Estimator is telling you that your current driving best aligns with the average projected range.Īs you drive, the Range Estimator is constantly seeking equilibrium with the trend bars, which is why the maximum and average projected ranges tend to fluctuate over the course of a long drive. The Trend Bars account for current energy consumption from driving and onboard systems, and indicate whether you are trending toward your minimum or maximum projected range. The Range Estimator feature most people seem to overlook is the Trend Bars, which is unfortunate because they are in my opinion one of the most useful aspects of the Bolt EV’s range estimator. Also like most other EVs, the Bolt EV’s Range Estimator displays the battery's state of charge (percent full), which is shown in 5% increments. While the Bolt EV’s Range Estimator, does include an average projected range, just like every other EV, it also provides maximum and average projected ranges that based on recent driving history, current conditions, and climate control settings. So why do so many drivers seem to have issues with the Range Estimator’s accuracy? From what I can see, it is because those drivers are focusing only on the projected range numbers rather than the Range Estimator as a whole. ![]() ![]() In my opinion, the Bolt EV's Range Estimator is one of the most accurate range projection tools available in any EV today. What Is the Chevy Bolt EV Range Estimator?Ĭurrently, most other electric vehicle automakers only include the EV’s estimated range and available capacity on the Driver Information Center (DIC) display however, GM chose to build a more complex tool to display additional information that updates in real-time. To illustrate, I will share some images of my Range Estimator during a recent trip to point out how it varies over time with various types of driving. In this story, I will describe the difference between the Chevy Bolt EV’s projected range and its Range Estimator, and I will explain how to use each element of the Bolt EV’s Range Estimator. ![]()
