Powering your house from your car – really?

Bi-directional charging might just be the game-changer for South Africans facing the ongoing challenge of load-shedding. Here’s the lowdown on how this innovative technology works.

The country’s prolonged energy crisis has sparked various strategies to combat load-shedding’s impact. From rechargeable bulbs to gas cooking and comprehensive solar systems, South Africans are exploring options. Now, electric vehicles (EVs) present an intriguing solution, thanks to bi-directional charging capabilities.

Bi-directional charging is a groundbreaking technology that allows plugged in electric cars to not only draw power but also contribute electricity back to the grid. An EV with this feature can serve as a mobile power source, covering home-energy needs and acting as a “battery on wheels” when not in use.

How does it work? Unlike traditional unidirectional chargers that send electricity in one direction (to the EV), bi-directional charging allows the flow of power in both directions. This means an EV can provide power to electronic devices, another EV, an entire home, and even the grid.

While the current global availability of battery-powered cars with bi-directional charging is limited, there’s hope on the horizon for South Africa with the upcoming Volvo EX90.

Volvo Car South Africa’s managing director, Greg Maruszewski, said, “In 2024, our local product line-up will welcome the new flagship EX90. While bi-directional charging for this model will initially be launched in selected markets, we believe South Africa’s ongoing energy challenges mean our customers will be especially receptive to this feature.”

Leveraging bi-directional charging technology, EVs in this programme contribute excess battery power, including renewable energy from sources like solar, back to the grid, reducing the reliance on fossil-generated electricity.

Could this be the next breakthrough for South Africa’s energy landscape?
