Next generation electric buses could hit 97% charging efficiency
One of the world’s leading independent bus manufacturers has confirmed a major leap forward in effectiveness for its forthcoming models.
Alexander Dennis, a subsidiary of NFI Group Inc., has shared data from recent Zemo Partnership testing of its electric vehicle charging systems. According to the report, the company’s next generation of public transport vehicles has hit 97% charge efficiency, which translates to a reduction in the cost of total lifetime ownership.
This is the best recorded UK zero-emission bus certification to date, and means that new models manufactured by the company will require significantly less energy to run, with operating costs potentially falling by at least 14% through the use of an Enviro400EV model compared with similar electric double decker buses with roughly equal battery size. Thanks to this super-efficient charging, battery life will also be extended as fewer charges will be needed, reducing overall wear and tear, with class-leading warrantable energy throughput of up to 1.6GWh.
‘We have focused on delivering benefits for our customers throughout the development of our next-generation electric buses. We’re delighted to announce a stunning 97% grid-to-wheel efficiency, certified by the Zemo Partnership’s zero-emission bus testing,’ said Alexander Dennis, Group Engineering Director, Chris Gall.
‘This will minimise energy requirements and slash costs for customers by delivering sustained savings throughout their buses’ long operational lives,’ he continued. ‘This is once again testament to the fantastic expertise of our engineering team and the collaborative working culture we have fostered with our key partners Voith Turbo, Impact Clean Power Technology and Grayson Thermal Systems.’
