The 2019 Tesla Model 3 Performance owned by Bjørn Nyland is making headlines once again, this time for showing a higher than expected capacity loss at 182,000 km (113,000 miles). This comes as a surprise, considering that Nyland sold the car in 2021 with only 8% degradation at around 80,000 km (49,000 miles). The significant increase in capacity loss has raised concerns about the impact of frequent fast-charging on the battery.
Nyland attributes the higher degradation to his charging habits, as he frequently used free Supercharging during his ownership of the vehicle. He estimates that the total usable capacity of the battery now stands at around 58 kilowatt-hours, with a buffer of approximately 4.4 kWh to account for the residual charge when the state of charge hits 0%. Despite the loss, Nyland still finds the range of the vehicle usable, with around 400 km (248 miles) in the summer and half that in winter conditions.
The unexpected jump in capacity loss has led Nyland to question the accuracy of the battery monitoring system (BMS) in the car. He suggests that the BMS may not provide an entirely accurate estimate of the battery’s total capacity, especially if the battery is not frequently charged to full or depleted to low levels. Nyland points out that Teslas that are not fully charged regularly tend to have a more pessimistic estimate of their remaining capacity.
Despite the higher than expected degradation, Nyland acknowledges that the results are not catastrophic, especially considering the car’s usage in Norway’s cold and harsh climate. He highlights that with the current capacity, the car can still achieve a range of around 250 miles (400 km) in the summer and half that in winter conditions. Overall, while the capacity loss may be higher than anticipated, the car remains functional and usable for everyday driving. The world of technology is constantly evolving, with new advancements and innovations being introduced every day. One of the latest developments in the tech industry is the emergence of augmented reality (AR) technology. Augmented reality has the potential to revolutionize the way we interact with the world around us, blending the physical and digital realms in ways that were previously unimaginable.
Augmented reality technology allows users to overlay digital information onto the real world, creating a seamless and immersive experience. This technology has already been integrated into various industries, including gaming, education, healthcare, and retail. With the rapid growth of AR technology, it is expected to become even more prevalent in the coming years.
One of the key advantages of augmented reality technology is its ability to enhance user experiences. For example, in the gaming industry, AR technology allows players to interact with virtual elements in the real world, creating a more engaging and immersive gaming experience. In education, AR technology can be used to supplement traditional teaching methods, providing students with interactive and visual learning experiences.
In the healthcare industry, augmented reality technology is being used to improve patient outcomes and enhance medical training. Surgeons can use AR technology to visualize internal organs and structures in real-time, allowing for more precise and effective surgical procedures. Medical students can also benefit from AR technology, using virtual simulations to practice complex medical procedures in a safe and controlled environment.
Retail is another industry that has embraced augmented reality technology. With AR apps, customers can try on clothes virtually, see how furniture would look in their homes, or even test out makeup products before making a purchase. This not only enhances the shopping experience for consumers but also helps retailers increase sales and reduce returns.
Overall, augmented reality technology is poised to have a significant impact on various industries, revolutionizing the way we interact with the world around us. As the technology continues to evolve and become more accessible, we can expect to see even more innovative applications and use cases emerge in the near future. With its potential to enhance user experiences and improve efficiency, augmented reality is definitely a technology to watch in the coming years.
