Electric cars have significant environmental advantages over conventional gasoline or diesel-powered cars but only if they are able to hold enough power while travelling from point A to point B. This main concern has been addressed by Highways England who operates, maintains and improves England’s motorways and major A roads.
The government-run agency has announced plans to test wireless power-transfer tech that will be built under the country’s major motorways to recharge EV cars on-the-go. For this purpose, the agency will construct an off-road testing site later this year where electric and hybrid cars with built-in wireless technology will charge up using compatible equipment beneath the ground. The feasibility study on the use of the prospective use of dynamic charging systems has already been done. What remains to be seen is whether such a scheme would be cost-effective. Highways England plans to continue to run experiments for 18 months before it finally decides whether to commit to an on-road trial.
Pioneering technologies such as charge-as-you-drive are already being developed elsewhere. Buses in South Korea in the town of Gumi fitted with compatible equipment such as coils that pick up electromagnetic fields generated by electric cables buried under the road.
Though the England project is still in its early stages, it has the potential to recharge low emission vehicles and thereby contribute to a sustainable environment.
