Advocates urge Paccar, Cummins and Daimler to stop lobbying to water down heavy-duty NOx standards

Automakers and truck-makers play a double game, proclaiming their greenness to the public while lobbying policymakers to water down or eliminate environmental regulations. Environmental and public health advocates write letters to the companies politely asking them to stop doing so.

In the latest round, a coalition of 24 organizations, including the Sierra Club, the Center for Biological Diversity, GreenLatinos and the Natural Resources Defense Council, have sent a letter to the CEOs of Paccar, Cummins and Daimler urging the companies to reverse their efforts to weaken implementation of the EPA’s heavy-duty nitrogen oxide (NOx) emissions standards, which are set to take effect in 2027.

The letter calls out the companies’ recent public statements backing a rollback of the standards—a position the groups say directly contradicts assurances the manufacturers have given investors about their readiness to meet the 2027 requirements. The groups point to manufacturers’ own earnings calls: Paccar stated it was “prepared” for the 35 mg NOx standard and Cummins said it would “be ready to launch” products under the 2027 rule.

“Paccar, Cummins, and Daimler must end their attempts to undermine implementation of heavy-duty NOx standards, threatening the health of the communities and drivers upon which the heavy duty industry relies,” the groups wrote.

The letter notes that heavy-duty trucks make up just 6% of the on-road fleet but account for 59% of the transportation sector’s NOx emissions and 55% of its particulate pollution, and cites American Lung Association findings that truck drivers face elevated exposure to diesel exhaust and higher lung cancer mortality.

“Cummins is marketing an aftertreatment system built for EPA27. Daimler is selling engines it calls compliant today. PACCAR told investors it was ready last year,” said Andrea Marpillero-Colomina, Policy, Research & Data Analytics Advisor at GreenLatinos. “They can’t sell readiness to shareholders while simultaneously buying delay from Congress.”

Teletrac Navman’s Energy Hub gives businesses a unified view of energy usage in mixed EV/ICE fleets

Connected mobility platform Teletrac Navman has launched a new feature within its all-in-one fleet management platform TN360. The new Energy Hub is designed to provide businesses with a unified view of energy usage across mixed-energy fleets, combining data about EV charging with legacy fuel data in a single platform.

“As businesses continue to adopt mixed-energy fleets, managing energy usage across fleet management platforms, fuel card systems, and multiple charging sources, including home, depot and public networks, is becoming increasingly difficult,” the company explains.

Energy Hub gives managers real-time vehicle data, including battery state of charge (SoC) and estimated remaining range. Building on Teletrac Navman’s existing telematics platform, Energy Hub supports configurable alerts and exception-based reporting that can identify overcharging, unusual fuel transactions and inefficient charging behavior.

Energy Hub’s dashboard provides fleet-wide visibility into energy consumption, transaction volumes, cost per kilowatt-hour and overall spend. Fleet managers can analyze trends, monitor live charging status, track charging events, and locate public charging infrastructure.

“The challenge is no longer simply collecting information but bringing it together in a way that supports better operational decision-making,” said Teletrac Navman CEO Alain Samaha. “Energy Hub helps businesses reduce fragmentation and gain clearer insights into energy performance, bringing these data points together into one platform and enabling a more integrated, data-driven approach to fleet management.”

Danisense’s new current transducer measures isolated DC and AC current in power electronics

Danisense has introduced a new current transducer for isolated DC and AC current measurement in PCB-mounted power electronics applications. The DP12IP measures currents up to 18 A and boasts a maximum linearity error of 10 ppm.

The DP12IP is based on closed-loop compensated fluxgate technology, and it uses a fixed excitation frequency and second-harmonic zero-flux detection. It accommodates measurement resistors up to 100 Ω at full scale. The package measures 32 mm and weighs 250 g, which allows it to fit into 1U power supplies and other space-constrained equipment.

As an isolated sensor, the DP12IP measures current in a power circuit while keeping its output galvanically separated from the circuit, so the measurement signal stays referenced to the low-voltage control electronics. Closed-loop fluxgate transducers continuously null the magnetic flux in the sensor core, keeping the magnetic element near zero field. That approach helps hold linearity error low and keeps DC measurement stable, and a 10 ppm linearity error keeps the ratio between the output signal and the measured current consistent across the operating range.

Typical applications for the DP12IP include magnet power supplies for particle accelerators, precision power supplies, precision servo drives for motion control, battery test benches, battery emulators, and power measurement and analysis systems.

“The DP12IP current transducer addresses the increasing demand for highly stable and accurate current measurement in next-generation power conversion and control systems,” said Loic Moreau, Danisense’s Sales and Marketing Director.

Why integrated FPC-based cell contact solutions are essential to battery pack manufacturing

Sponsored by Churod Electronics.

Increased battery density is the endgame of all cutting-edge battery design, improvements cannot come at the expense of safety or cost limitations. The question then becomes how to push the envelope in a safe and cost-effective way. Monitoring the state-of-health of cells is at the top of the list of considerations.

Accurately measuring ambient factors like temperature and voltage provides critical data to the BMS. For years, this could be done through discreet wiring, though this method was inefficient, and the quality was lacking. In today’s designs, flexible printed circuit boards (FPCs) are replacing discrete wiring. These FPC-based systems are the newest generation of cell contacting systems. They simultaneously bring down the cost of pack manufacturing and improve reliability in manufacturing and data harnessing.

The quality of data is essential in order to safely maximize energy density. This white paper from Churod Electronics details the hows and whys of FPC-based Cell Contacting Systems and how this cost-effective, yet reliable tool is a key to modern battery pack efficiency.

char.gy and Devon Council partner on kerbside EV charger trial

Curbside charging (kerbside to our British colleagues) is the solution to the problems faced by EV owners who rely on on-street parking. Curbside chargers are now common sights in London, and they’re spreading to other regions of the UK.

On-street charge point operator char.gy is set to begin a trial of new on-street EV charge points in Devon. The company will deploy 30 new on-street charge points installed across the county. All will be powered by 100% renewable electricity.

The project is supported by the UK government’s Local Electric Vehicle Infrastructure (LEVI) Fund. When the trial is completed, the lessons learned will inform the next phase of installations.

According to Zapmap, the UK had around 87,000 public charging points at 45,000 locations as of late 2025. So far, the lion’s share of these have been installed in urban areas, but they’re starting to be rolled out in larger, rural counties such as Devon.

char.gy operates what it describes as the UK’s fourth largest on-street charging network—it has over 5,000 public charge points currently in operation.

“This trial is an important step in turning LEVI funding into real, usable infrastructure for communities,” said John Lewis, CEO of char.gy. “For many drivers in Devon, access to reliable on-street charging is essential to making the switch to electric. By starting with a focused trial, we can learn what works locally and help lay the foundations for a wider rollout that gives residents confidence to go electric.”

MAHLE introduces a new range extender engine and a rare earth-free electric motor

Automotive supplier MAHLE has developed a range extender system for heavy-duty trucks that packages a combustion engine and a generator into part of the space an electric truck’s battery would normally occupy. The system is designed to replace about one-third of the battery capacity of a typical electric truck with a compact diesel engine.

The assembly is a self-contained unit: the generator, engine, thermal and fluid management, fuel tank, AdBlue tank and exhaust treatment sit inside one box that drops into existing battery-electric platforms. The high-voltage generator, which features a newly developed oil cooling system, delivers 110 kW continuous and up to 130 kW peak power, and boasts a power density of more than 7 kW per kilogram.The unit’s thermal management system provides 48 kW of high-temperature and 15 kW of low-temperature cooling.

Swapping part of the battery for the range extender cuts the rear axle load by about 400 kg and the total vehicle weight by about 600 kg, MAHLE explains.

Electrification of heavy trucks.

MAHLE has also developed a new Contactless Transmitter (MCT) electric motor for the drive axles of heavy commercial vehicles. It uses no permanent magnets and therefore no rare earth elements, which the company says saves up to 3 kg of rare earth magnets per vehicle compared with a benchmark permanent magnet synchronous motor.

The motor is 10% lighter and more efficient than a permanently excited design under real driving conditions, according to MAHLE. It delivers a peak output of 370 kW and torque of over 900 Nm at 3,900 rpm, and reaches about 95% efficiency in the EU’s VECTO simulation cycle.

“Our range extender is the key to disconnecting the market ramp-up of battery-electric trucks from the inadequate pace of infrastructure development,” said Marco Warth, MAHLE’s Vice President of Corporate Research and Advanced Engineering.

New Mitsubishi Eclipse Sportback EV to offer both J1772 and NACS charging ports

Many automakers are fitting new cars with NACS (SAE J3400) charging ports instead of the more traditional CCS ports. For road trips, this allows drivers to use Tesla Superchargers without an adapter, but most EV owners will need to replace their home chargers if they buy a new NACS-equipped EV.

Mitsubishi is taking a different tack. The 2027 Mitsubishi Eclipse Sportback, an all-new EV that will be launched across North America in the fall of 2026, will offer both a J1772 and a NACS charging port as standard equipment on all models.

Most Charged readers will be conversant with the various charging standards in use today, but for new EV owners, charging may seem like a more complex issue than it is (and good luck getting a car salesperson to explain it). Both the CCS and NACS standards allow both AC (at home) and DC (on the road) charging, but NACS handles both AC and DC charging with the same plug.

Thus, the Mitsubishi Eclipse EV will be able to charge at Levels 1 and 2 using the J1772 plug found on most home chargers and portable chargers, and it will be able to use DC fast charging (at up to 150 kW) or Level 2 charging using the NACS plug.
