Exro and SEA Now Developing Dennis Eagle Trucks with 800V........
this particular agreement moves the partnership into a new commercial phase for SEA Electric’s next generation F59, which the company says is will be perfect for short stop-start delivery runs.
Other collaborations between the two companies include developing an SiC 800V application for a next-generation Dennis Eagle heavy-duty truck. Exro says that the Coil Driver optimises the performance and efficiency of electric motors and batteries through power electronics, effectively acting as an electronic gear.
Here, the physics of coil-switching is utilised to expand the capabilities of motors by enabling two separate torque profiles (low-speed torque and torque at speed). Exro points out that this technology can reduce the number of motors and the size of batteries and eliminate the need for mechanical gearing allowing electric vehicles to achieve better acceleration, gradeability, high-speed torque and improved efficiencies for a lower cost.
