Tesla Motors Inc vehicles have the ability to convert the kinetic energy into chemical energy stored in the battery via a process called regenerative braking, or simply regen. This has been shown in a video put together by YouTuber and Tesla owner Bjørn Nyland. To show the energy consumption and generation in real-time, the instrument cluster of each vehicle was filmed.
Tesla cars have a unique ability
Bjørn used the Model X to demonstrate the ability to recoup energy in the Model S battery by towing. The Model X, when combined with 20″ wheels, can tow up to 5,000 lb. (2,267 kg). With the 22″ wheels, the Model X can tow 3,500 pounds. Even though such a scenario is very unlikely, it does show a very interesting use case of boosting a battery’s range by artificially simulating regen, notes a report from Teslarati.
As per the video, the demo used a single motor rear wheel drive standard 85 Model S. Since the motor was single, the energy generated from the process was less than what would have been generated by towing a dual motor configuration. Also, considering the length of rope used in towing, Bjørn believes the limit of 60 kW gen was not hit owing to the speed limit with which they towed, notes Teslarati.
From the demo, Bjørn collected the following data: Total distance traveled -10.7 km (6.6 miles); Time: 15 minutes; Model X consumed 14.9 kWh; Model S gained 7.2 kWh; Heat loss in both cars combined: 4.7 kWh; Estimated energy for driving both cars: 3 kWh; Average charging power 28.8 kW; Estimated loss in pulling: 20%; Estimated loss in charging: 20%.
It must be noted that Tesla Motors Inc does not recommend towing a Model S with wheels on ground, or the powertrain energized, as the “damage caused by transporting is not covered by the warranty.”
Model X gets impressive sales in Canada
Separately, Canadian EV market is dominated by American carmakers – Tesla Motors Inc and GM. And, with the launch of the Model X and upbeat sales of Chevrolet Volt, the country recorded the highest sales in Q3 2016, report Electrek. Canada already has over 20,000 plug-in EVs, and from July to September, it sold more than 3300 new EVs – a rise of 60% yoy, as per data from Fleetcarma’s.
One interesting point in the report was – the deliveries for the Model X surpassed the best-selling EV of 2015 in Canada and also the Model S in the Q3. Also, both of Tesla’s car – the Model X and Model S were among the top four EVs in Canada. But, the Chevy Volt remains the top-seller in the country. The Model S and Nissan LEAF hold 18% of the market through September 2016, as per the data. This is really impressive as Tesla’s vehicles are atleast twice as expensive as other vehicles in the market.
