Allison Transmission has selected the Vigor+ lithium-ion battery pack from EnerDel as approved equipment for the Allison H 40/50 EP hybrid system, which is used in heavy-duty transportation applications such as transit buses.
‘EnerDel is excited to have our Vigor+ pack receive full support-equipment approval from Allison Transmission,’ says Ben Wrightsman, director of strategic applications for EnerDel. ‘Entering into a relationship with Allison further solidifies our position as the lithium-ion ESS solutions provider of choice in the hybrid bus market.’
Allison's H 40/50 EP series is a two-mode parallel-hybrid transmission that is equipped with regenerative braking technology and available in configurations up to 246 kW (330 hp). These hybrid transmissions have been in production for more than 10 years and are integrated into thousands of buses and coaches, the company says.
