A power outage is an inconvenience for most, but for people who rely on electricity for essential medical or mobility equipment, it can be life-threatening. A new initiative, dubbed “Power Wheels,” aims to test how electric vehicles (EVs) can act as temporary backup power sources for disabled individuals and those with medical dependencies in the UK.
The Problem: Power Cuts and Vulnerable Populations
The UK’s increasing reliance on electricity means that disruptions, whether from storms or infrastructure failures, can have severe consequences for those who need constant access to powered devices. Over 860,000 people in the UK are supported by the Motability Scheme, many of whom depend on electric-powered equipment. A power cut can mean more than just inconvenience; it can mean immediate danger.
How ‘Power Wheels’ Works: EVs as Backup Generators
Funded by Ofgem, Motability Operations (the company behind the Motability Scheme) is running the Power Wheels project in the North East of England. The region already has over 12,500 EV drivers supported by Motability. The project explores how EVs can power homes during outages, ensuring vital medical equipment and mobility aids remain operational.
The first phase focused on ensuring the technology is safe and reliable for home use. This includes:
– Accessible two-way charging systems
– Direct charging of medical devices from EVs
– Battery charge management to maintain sufficient power.
Existing Technology: Vehicle-to-Load and Vehicle-to-Grid
Many modern EVs already have “vehicle-to-load” (V2L) capabilities, allowing them to power appliances. Some even have “vehicle-to-grid” (V2G) systems that can feed energy back into the national grid. The Power Wheels project seeks to harness these technologies for immediate local benefit.
“As the UK moves to electric vehicles, it’s vital that this transition supports disabled people’s freedom and independence,” says Andrew Miller, Chief Executive of Motability Operations. “Power Wheels will help ensure new technologies are designed around real lives and needs.”
Next Steps: Real-World Testing with 30 Motability Customers
The next phase involves direct collaboration with 30 Motability customers to assess how the technology works in practice for various disabilities and requirements. This testing will refine the system to maximize its effectiveness.
The Power Wheels project highlights a critical yet often overlooked aspect of the EV transition: ensuring that new technologies benefit all members of society, including those most vulnerable to disruptions. By turning EVs into mobile power backups, Motability is pioneering a solution that could save lives during emergencies.
