The Tesla Semi has been a groundbreaking innovation in the transportation industry. With a promised range of 500 miles on a full charge, it represents a significant step towards sustainable freight transportation. This range is not just a theoretical figure, it’s based on real-world testing with the truck fully loaded at 82,000 pounds gross combination weight. The 500-mile range has been a focal point of discussion, sparking interest and curiosity among both enthusiasts and skeptics.

While the Tesla Semi’s range has been applauded by many, it has also been met with skepticism and criticism. The debate centers around the truck’s practicality, particularly in winter conditions where electric vehicles are known to suffer range loss. Critics argue that the range might not be sufficient for long-haul trucking, especially in regions with harsh winters. They point to potential issues like battery efficiency loss in cold temperatures, raising questions about the Semi’s ability to replace traditional diesel trucks.

According to recent studies and real-world testing, the Tesla Semi can be a suitable replacement for approximately 87% of semi-truck loads, even considering winter range loss. This introduction sets the stage for a comprehensive exploration of the Tesla Semi’s 500-mile range, its performance in winter conditions, and its potential to revolutionize the freight transportation industry.

Meyers Manx, the original maker of the Volkswagen Beetle-based, fiberglass-bodied beach buggy from the 1960s, just published the starting price for its all-new, all-electric Manx 2.0 electric buggy, and it’s not exactly cheap.

Revealed last year at The Quail, A Motorsports Gathering, the company’s first all-new vehicle in nearly 20 years starts at $74,000 for the base variant with the 20-kilowatt-hour battery pack and yet-to-be-released performance figures. That’s almost as expensive as the recently introduced Tesla Model S Standard Range, which starts at $78,490 and offers a 320-mile range.

The base MSRP came with no extra information and was casually thrown in a sentence at the end of the press release for the company’s new Resorter Neighborhood Electric Vehicle (NEV), which debuted last week at The Quail, so we still don’t know how much the top-of-the-line model will set prospective customers back.

In a recent advance, researchers have created a novel battery charger that can support present and future generations of battery packs for EVs across a vast range of voltages: anything between 120 and 900 volts. The new tech is described in a study published in the September edition of theIEEE Transactions on Power Electronics.

These next-generation batteries will bring shorter charging times while also weighing less, which means that EVs can be ready to drive sooner and travel farther on a full charge. “However, charging these high-voltage batteries with existing chargers degrades the efficiency, due to operating at twice the rated voltage,” says Deepak Ronanki, an assistant professor at the Indian Institute of Technology Madras, in Chennai, India, and an IEEE senior member who was involved in the study.

Ronanki and doctoral research scholar Harish Karneddi created a universal charger capable of supporting voltages between 120 and 900 V—something they say had not yet otherwise been achieved.

Ronanki and Karneddi’s battery charger is actually a two-stage charger, with a front-end boost-buck power factor correction (PFC) circuit followed by a reconfigurable DC-DC converter. As the term “boost-buck” suggests, the battery charger can boost the voltage when the battery voltage is greater than the input voltage and, conversely, buck the voltage when the battery voltage is less than the input voltage.
