The Future of EV Charging is Bidirectional, If You Can Afford It
Idle EVs could act as massive batteries for homes and the energy grid. But the technology to pull this off is tricky.
In 2020, EVTEC installed five charging stations outside Islington Town Hall in London, and the company will launch another trial with Swiss car-sharing provider Mobility later this year using 50 Honda electric cars. The biggest sticking point, however, remains the high installation costs for bidirectional chargers, says John Murray, head of EVs at the energy consultancy Delta-EE—even though prices have dropped by up to 50 percent in the last two to three years. However, EV owners will still need to be convinced that recurrent charging and discharging will not degrade their batteries faster, says Ying Xie, a professor of supply chain management at Anglia Ruskin University.
