Sponsored by Littelfuse Three scenarios with dedicated power electronic solutions As the electrification of heavy-duty or commercial vehicles gains more acceptance, charging larger batteries than the ones in electric passenger cars increases in importance. Because time is money, especially in logistics, the preferred options are increasing charging power or assigning idle times for charging. These… Read more »

TWAICE battery analytics platform promises enormously valuable insights at every point in a battery’s lifecycle
How healthy is your battery pack? As the old saw goes, if you can’t measure it, you can’t manage it. As the EV ecosystem develops, there will be an increasing need to measure and manage the performance of battery cells. Cell manufacturers need a standardized way to evaluate test data for new cells; EV designers… Read more »
Sensata introduces next-gen BMS for 1,000 V systems
Sensata, a sensor, controller and software firm, has introduced a next-generation BMS designed for high-voltage applications, including electric trucks, buses and material handling vehicles. It’s part of the Lithium Balance product line, and will be available in early 2023. The Lithium Balance n3-BMS is composed of up to 30 Cell Monitoring Units, a Master Control… Read more »
Bollinger Motors reveals B4 commercial electric truck
Bollinger Motors’ new B4 is a Class 4 all-electric fleet truck that features a cab-forward design. It’s designed to offer maximum cargo volume, accommodate unlimited adaptation, and prioritize safety. “The cab-forward design is a radical change from our previous concepts,” says founder and CEO Robert Bollinger. “And that’s on purpose. We listened to our commercial… Read more »
ONE’s hybrid battery pack combines the best aspects of two chemistries to deliver 600 miles of EV range
Q&A with ONE CTO Dr. Steven Kaye. There is a wide range of characteristics that describe the performance of any given battery chemistry: energy density, specific energy, specific power, discharge efficiency, self-discharge rate, cycle life, calendar life, and—not the least important—cost. Some types of Li-ion chemistries are really good in a few characteristics but fall… Read more »
MAN to begin large-scale production of batteries in Nuremberg by end of 2024
Commercial vehicle manufacturer MAN Truck & Bus will invest around 100 million euros over the next five years at its facility in Nuremberg, Germany to develop production of high-voltage batteries for electric trucks and buses. Initially, the batteries will be manufactured manually in a small series production phase that will last about two and a… Read more »
Daimler Truck works with German machinery manufacturer Manz to develop battery tech
Daimler Truck has acquired a ten-percent stake in the German high-tech machine manufacturer Manz. The two companies will form a strategic partnership to establish a pilot line for the production of battery cells and the assembly of batteries at Daimler Truck’s Mannheim site. The aim is to develop innovative battery technology and associated production processes… Read more »
Power Integrations introduces new line of gate-driver boards
Integrated circuit maker Power Integrations has introduced a new line of gate-driver boards designed for electric buses and trucks as well as electric construction and agricultural equipment. The SCALE EV gate-driver boards are rated at 1,200 V for 400 V and 800 V systems. Each is composed of two reinforced gate-drive channels, associated power supplies and… Read more »
2022 GMC Hummer EV Edition 1 first drive: five tons of fun
The rebooted electric Hummer is an absurd vehicle, in some ways, but it’s an extremely well-executed absurdity. How do you review a 5-ton electric truck that accelerates from 0 to 60 mph in about 3 seconds? No other vehicle on the market is even close to direct competition. And comparing it to mass-market EVs like… Read more »
Rivian working on 800-volt architecture, bidirectional charging, in-house drive units and battery cells
EV startup Rivian’s Q4 2021 Shareholder Letter is reminiscent of the ones we used to see from a certain other Californian EV startup in its idealistic younger days—full of forward-looking technical innovations. Rivian appears to embracing several current trends on the EV scene—going bidirectional and moving towards 800 volts, LFP cells and more in-house production… Read more »
