Thermal runaway in EV batteries is a serious concern with potentially catastrophic consequences. When a single cell overheats due a fault it can trigger a chain reaction in adjacent cells, […]

Honda and Nissan are currently considering a merger that goes far beyond the agreed cooperation on software-defined electric cars. Both sides have now officially confirmed their plans to merge. It will be accompanied by a production partnership to build vehicles in each other’s plants.
Lilium urgently needs a buyer in the wake of its insolvency. Last week, there were reportedly still several interested parties. However, it has now emerged that the air taxi specialist has made almost all of its 1,000 employees redundant. Operations are to be discontinued.
Commercial work trucks have historically utilized mechanical Power Take Off units (PTOs) to transfer power from the diesel engine and transmission to operate hydraulic, water, vacuum pumps, pneumatic compressors, etc. An ePTO replaces the traditional mechanical PTO for electrified vehicles. ePTOs are a broad term and represent many implementations and form factors, which can be confusing, but the benefits include reduced engine runtime, lower emissions and fuel and maintenance savings.

Australian mining company Fortescue has placed a $400-million order with Chinese heavy equipment maker XCMG (Xuzhou Construction Machinery Group). The sale, which includes over 100 pieces of electric equipment, is the largest single export deal in XCMG’s history.
The massive contract includes a wide range of battery-electric heavy equipment, including electric wheel loaders, dozers, semi-trucks and graders, which will be delivered to Fortescue’s mining operations in Pilbara, Australia, in stages between 2025 and 2030.
Fortescue says the use of this equipment will displace millions of gallons of diesel fuel at the company’s iron ore operations over the life of the assets.
“We’re moving rapidly to decarbonize our Pilbara iron ore operations and eliminate our Scope 1 and 2 terrestrial emissions by 2030,” said Fortescue Metals CEO Dino Otranto. “To achieve this target, we will need to swap out hundreds of pieces of diesel mining equipment at the end of their life with zero-emissions alternatives.”
XCMG is embracing electrification across its product lines. “XCMG is dedicated to long-term sustainable development, offering high-end, intelligent and green product+scenario full-life-cycle solutions to global customers,” said XCMG Chairman Yang Dongsheng. “The company has achieved electrification across its entire product range, and new energy products account for 18 percent of revenue.”
German adhesives and equipment manufacturer DELO Industrial Adhesives has added a new retraction valve to its lineup of adhesive dispensing systems.
DELO-DOT RE offers the repeatability and control of higher-end systems like jetting or volumetric needle dispensing and the simplicity of direct dispensing from cartridges. Enabled by compressed air, the pneumatic retraction valve features properties that support a high level of repeatability and help ensure a quality bond, according to the company. Its retraction mechanism enables heightened precision and control. Following dispensing, rather than simply ceasing air compression, the needle pulls back slightly to reverse the flow of adhesive. This creates a vacuum effect to curtail adhesive flow and prevent dripping.
DELO-DOT RE can dispense adhesive droplets as small as 0.09 µl, which is smaller than applying adhesive directly from cartridges. It dispenses with a standard deviation of less than 3%, much lower than direct dispensing via cartridge and in line with many higher-end jet valves.
At 33 x 25 x 112 mm, the valve can be integrated into most production lines, requiring only an additional 18 mm to accommodate its width. A weight of less than 100 grams has minimal impact on existing systems.
The actuators are hermetically separated from the dispenser’s fluid system, which results in simple, tool-free assembly and disassembly. Tool-free cartridge replacement is also possible via spring-loaded reinforcement clips located on the actuator component. Unlike volumetric valves, any part of the valve which at any point comes into contact with fluid is entirely encapsulated and can be easily replaced.
“All these properties culminate in many possible application fields. In semiconductor potting, as well as active alignment processes for cameras, dispensing directly from the cartridge is often preferred. However, unlike in direct dispensing, the retraction valve does so without dripping or bubbling, thus increasing yields,” the company said. “Semiconductor lid attachment is often performed via direct dispensing as well. Here, the valve’s retraction mechanism provides the control necessary for bondline thickness continuity.”

ChargePoint and GM have announced a collaborative effort to install hundreds of ultra-fast charging ports at strategic locations across the US under the GM Energy brand.
The new EV charging stations will feature ChargePoint’s latest innovations. Many will support the new Omni Port system, which allows vehicles with CCS or NACS charging ports to seamlessly charge at any charger, with no need for adapters. Many will support ChargePoint’s Express Plus platform, which is capable of charging speeds up to 500 kW.
ChargePoint and GM also plan to implement an incentive program designed to make it easier for third-party charge point operators (CPOs) to own and operate EV charging infrastructure.
The companies aim to open the new batch of charging stations by the end of 2025.
“Continuing to provide customers with better charging options helps to remove barriers to EV adoption and improve the ownership experience,” said GM Energy VP Wade Sheffer. “Today, GM drivers have access to hundreds of thousands of places to charge, and this collaboration with ChargePoint adds even more reliable, accessible and convenient charging experiences.”
“Our collaboration with GM represents a significant investment in the infrastructure to enable fast and easy charging for all,” said Rick Wilmer, CEO of ChargePoint. “Together, ChargePoint and GM will deliver a seamless fast charging experience via reliable charging hardware managed by our industry-leading software platform.”

Multi-trade contractor Power Design has selected US-based EV charger supplier Blink Charging to provide EV chargers and charging services at select locations.
The agreement includes the provision of 429 Blink chargers, with a total of 723 plugs for use by residents at Power Design projects throughout the US. The charging stations will be installed across multiple development types—primarily luxury multifamily apartments and condominiums.
Power Design will own the Blink charging stations, and when installed, the owners or property managers of the projects will take ownership. This new agreement is the latest in a series of collaborations between the companies.
“As the demand for EVs continues to rise, so does the need for accessible and reliable EV charging services where people live,” said Power Design Energy Account Manager Mike Kuhn. “This is where the value-added benefit of on-site charging takes living spaces to the next level of modern convenience and resident-friendly amenities.”
