Enevate models new battery cells that can be optimized for energy, power or cycle life

Enevate Technologies has introduced Trifecta, a licensable battery cell technology designed so engineers no longer have to choose between specific energy, power and cycle life. Intended applications include drones, humanoid robots, race cars, data center power systems and electric aircraft.

Enevate Technologies says Trifecta designs match or exceed the specific energy of leading lithium-metal and solid-state cells without their usual safety and charge-rate problems. The company has published five configurations, all modeled designs that build on a proof of concept with earlier prototype cells.

Trifecta Surge is the power version: 400 Wh/kg at a 40 C rate for 500 cycles, intended for racing, data center power and heavy-lift drones. Trifecta Prime is modeled at 425 Wh/kg, 20 C and 1,000 cycles for humanoid robots, commercial drones and eVTOL aircraft.

Two configurations trade cycle life for specific energy. Trifecta Sprint reaches 480 Wh/kg at 20 C but lasts only 20 to 50 cycles, for high-power, limited-use systems. Trifecta Range offers the highest specific energy: 545 Wh/kg, at a 1 C rate and the same 20 to 50 cycles, for long-endurance and single-mission drones.

Trifecta Endurance is the middle option: 475 Wh/kg at 1 C, with a 1,000-cycle life for long-life platforms at moderate power.

Enevate Technologies works with each customer to match or tailor a configuration, then helps arrange production by a licensee, through a custom build or by the customer’s existing supplier. Battery manufacturers interested in licensing Trifecta to produce cells for their own customers are invited to contact the company.

Enevate Technologies builds on technology and team members from silicon-anode developer Enevate Corporation, whose assets an affiliate of Quantum Valley Investments acquired during Enevate Corporation’s liquidation.

“Engineers have spent years designing around their batteries,” said Benjamin Park, CEO of Enevate Technologies. “Trifecta flips that. We want to have open conversations about how our technology can change how you design things.”

LAZ and EverCharge partner to expand EV charging at apartment and condo properties

LAZ Parking and EverCharge, a subsidiary of indiGOtech (GO), have announced a joint venture to offer EV charging services for apartment and condominium residents. The partnership combines LAZ’s parking and real estate operations with EverCharge’s SmartPower management technology.

LAZ operates approximately 2.1 million parking spaces at 5,700 locations in 639 cities in the US and Canada. The company has established relationships with property owners and operators.

EverCharge’s SmartPower technology allows multiple chargers to share a building’s available electrical capacity, enabling up to five times as many charging ports to operate using the same power supply, compared to unmanaged charging. This can allow more residents to charge their vehicles without requiring major electrical upgrades.

EverCharge operates some 10,000 charging ports at over 1,000 multifamily residential sites.

The two companies plan to offer a multifamily charging service that provides charging solutions for residents without requiring property owners to manage the installation and operating process.

“LAZ has always been about more than parking,” said Alan Lazowski, Chairman and CEO of LAZ. “The future is charging right where people park. Our joint venture with GO expands our charging network to 25,000 ports in North America, and we’re just getting started. Our broader relationship with GO also gives us the opportunity to explore how the places we operate can evolve alongside electric and autonomous vehicles.”

“Multifamily dwelling charging represents one of the largest infrastructure opportunities in the transition to electric transportation,” said John Lin, CEO of EverCharge. “We’re a leader in deploying intelligent charging for this market, and we’re working with LAZ to bring our platform to more properties and drivers.”

Infineon’s ENDOPACK Cell embeds 1,200 V SiC MOSFETs in traction inverter PCBs

Infineon Technologies has introduced ENDOPACK Cell, which embeds its 1,200 V Automotive Gen2p CoolSiC MOSFETs directly in a printed circuit board (PCB). ENDOPACK Cell is designed to help automakers develop traction inverters faster and scale them across vehicle platforms.

ENDOPACK is Infineon's new brand for chip-embedding technologies in a range of voltage classes, form factors and applications. Infineon uses chip embedding in low-voltage production and is extending it to high-voltage power electronics. The company says ENDOPACK Cell is the industry's first automotive-qualified, high-voltage chip-embedding solution designed for PCB integration.

ENDOPACK Cell uses standardized PCB design processes and manufacturing infrastructure. Infineon says this enables development cycles up to three times faster than conventional designs. ENDOPACK Cell is also designed to transfer to a design-agnostic production line, allowing design iterations without repeated changes to the manufacturing process.

In ENDOPACK Cell, the power semiconductors are embedded directly in the PCB structure instead of being placed on top of a substrate. Infineon says the architecture reduces inductance to below 2 nH (compared with 20 nH), which enables 30% lower switching losses and approximately 99.5% efficiency under CLTC conditions. According to Infineon, prototype and simulation data indicate peak power density of up to 200 kW/L and a potential 7% improvement in vehicle range.

Chip quantity and placement can be adapted to power requirements and installation space, and geometry is no longer largely determined by a fixed module housing. Multiple cells can be integrated into a single PCB, so the power stage can be configured for the performance and architecture requirements of a specific vehicle platform.

ENDOPACK Cell is ready for mass production. Vehicles using it are planned to enter mass production in 2027.

Navitas launches 2,300 V full-bridge SiC module for megawatt charging and grid storage

Navitas Semiconductor has introduced a family of 2,300 V full-bridge silicon carbide (SiC) power modules designed to improve efficiency and power density in solid-state transformers, grid-scale battery storage, solar inverters and EV megawatt charging infrastructure.

The G4H08MT23GB4 family uses the SiCPAK form factor and has an on-resistance of 8 mΩ. The modules are based on Navitas's fourth-generation GeneSiC Trench-Assisted Planar architecture and extend the company's 2,300 V and 3,300 V ultra-high-voltage SiC portfolio.

An aluminum nitride active-metal-braze substrate provides heat spreading and supports isolation of more than 5 kV. The epoxy-resin potting is designed to reduce internal stress and limit moisture and contaminant ingress. Navitas says the potting has 10 times the thermal conductivity of silicone gel.

Navitas says the optional high-current press-fit pins have twice the current-carrying capability per pin of standard press-fit connections. An optional pre-applied thermal interface material (TIM) is designed to simplify and standardize heatsink assembly.

The family will be qualified to AEC-Plus, an internal reliability benchmark that Navitas says goes beyond AEC-Q101 and JEDEC requirements. AEC-Plus includes dynamic reverse bias and dynamic gate switching tests to represent fast-switching mission profiles. AEC-Plus also more than triples the duration of static high-temperature, high-voltage tests and adds extended power-cycling and temperature-cycling testing.

Samples are available in four versions, with or without the pre-applied TIM and with standard or high-current pins. A double-pulse test system, the EVB-UHVSIC-GB-E-DPT-1, is available on request to help engineers evaluate switching performance.

"Our fourth-generation GeneSiC Trench-Assisted Planar architecture continues to push the limits of what's possible in ultra-high voltage SiC," said Paul Wheeler, Vice President and General Manager of Navitas's SiC Business Unit. "This new 2300 V module delivers a leading RDS(ON) of any device using the SiCPAK form factor, giving system designers a proven, reliability-tested building block for the solid-state transformers and energy storage systems that are reshaping grid and AI data center infrastructure."

EcoG and Siemens partner to implement a new generation of EV charger software

Munich-based EcoG and electrical powerhouse Siemens are combining their automation and charging technologies to support manufacturers of EV fast charging hardware. EcoG is now an official Siemens Product Partner for SIMATIC automation systems, and will handle system integration and field operations.

More than 50 manufacturers of DC fast chargers use technology from both companies. Upgrading to the EcoG operating system will provide manufacturers and operators with ongoing software updates and support for upcoming requirements, including the Cyber Resilience Act and ISO 15118-20, which the EU will require new charging points to support starting in 2027. The system supports Plug & Charge and the Megawatt Charging System (MCS) for heavy-duty vehicles. It also enables billing that complies with German calibration law (Eichrecht).

“This partnership goes beyond a pure technology partnership,” said EcoG CEO and cofounder Jörg Heuer. “We are laying the foundation to take one of the largest charge point portfolios in the market into the future on the software side. Manufacturers can quickly bring their chargers up to date without having to redevelop them. The SIMATIC architecture stays in place—we simply replace the charging module.”

“Our customers build their charging systems on SIMATIC automation, and that will not change,” said Siemens Digital Industries Product Manager Automation Systems René Kuroczka. “For integration in the field, we have found a partner in EcoG with whom we combine an established charging infrastructure ecosystem with industrial automation.”
