One of the many critical factors holding back widespread adoption of Class 8 battery-electric semis is range.
Along with the necessary charging infrastructure, the next generation of batteries must provide enough juice to power long-haul, zero-emissions rigs.

As part of the company's new Onyx Strata series, Proterra says its the most energy-dense battery pack its built to date, with a total gravimetric density of 176 Wh/kg, volumetric density of 270 Wh/L, enabling a 750 kWh energy system.
The H2-23 pack also boasts software compliant to SAE J1939 and ISO26262.
"The new H2-23 battery pack represents more than just a technological advancement — it embodies our renewed focus on powering the shift to a sustainable future," said Claire McConnell, chief business officer at Proterra. "We've created a solution that delivers unparalleled performance even in the most challenging conditions. Every mile driven with our technology helps bring our customers closer to their zero-emission goals."
Proterra adds that all of its products are designed, engineered, and built in the U.S.
The H2-23 will be making its official debut next week alongside two additional new Proterra Onyx Series batteries, the Slate and Strata, at the 2025 ACT Expo in Anaheim, California.
