Sea Electric's new Sea-Drive 250 battery-electric power system for Class 8 trucks will feature an optional hydrogen range extender (RE). 

The Sea-Drive 250 model (and the optional RE model) is designed for vehicles with a GVWR/GCWR of up to 80,000 lbs, in Class 8 straight-truck or day-cab configurations, such as drayage and refuse.

In a major change, Sea Electric intends to pair the power system with a 45kW hydrogen fuel cell, extending the potential range, with the architecture set to have far-reaching implications in the sector.

Sea-Drive 250 Power System New Features

The new designation for the Sea-Drive power system joins other solutions developed by Sea Electric, namely the SEA-Drive 70, 100, 120, and 180, which have more than 2 million miles of real-world use in a range of truck, bus, and light commercial applications.

Featuring all the attributes of the other systems available, the Sea-Drive 250 will also feature:

• Maximum power of 670 hp (500kW).

• A peak torque of 4,579 lb-ft

• Power drawn from a 250-kWh battery pack.

“The combination of battery electric with the optional fuel cell extender will optimize weight and cost, whilst delivering the full fleet duty-cycle requirements, with performance that has never been seen before in this segment, said Tony Fairweather, Sea Electric Founder and CEO.
