EV Charging During Load Shedding in SA — What Actually Works

Range anxiety and load shedding are the two objections that come up first in almost every South African conversation about EVs. Load shedding is the more fixable of the two in practice — it's a scheduling problem you can plan around, not a fundamental blocker, as long as you understand how charging actually behaves around an outage.

Scheduled charging: the tool most EV owners underuse

Every EV sold in South Africa in the current model years includes some form of scheduled charging, set either through the car's own infotainment system or a companion smartphone app. You set a departure time or a charging window, and the car handles starting and stopping charging within that window automatically — including working around a known load shedding block if you've set the schedule accordingly.

Pair this with the EskomSePush app, which publishes load shedding schedules typically 24-48 hours in advance. Checking it before you set tomorrow's charging schedule is no different from checking it before you plan any other appliance-heavy task around the house — it just needs to become part of your routine the same way it already is for laundry or geysers.

Home charging vs relying on public stations

Home charging is the more load-shedding-resilient option by default, because you control when it happens and can schedule around outages directly. Public charging stations are a different story — unless a specific station is linked to an off-grid power source such as solar, it will typically go offline during load shedding along with everything else on that part of the grid. A small number of fully off-grid public stations do exist in South Africa and remain online regardless of load shedding stage, but they're still the exception, not something to plan a trip around by default.

When solar and battery backup is actually worth it

If you're already installing — or already have — a solar PV system with battery storage to cover the house through load shedding, extending that same system to cover EV charging removes the problem entirely: you're charging from stored solar energy rather than the grid, and load shedding stops being a factor for the car specifically. The catch is sizing — an existing backup system designed around household loads may not have the spare capacity for EV charging on top, so check this with a qualified installer rather than assuming it'll just work.

Installing solar and battery storage purely to solve EV charging, with no other household backup need, is a much bigger and more specific financial decision, and not one this guide can size for you — get a firm quote based on your actual daily charging needs before committing either way.

Common mistakes

• Not setting a charging schedule at all, and then being caught out when charging happens to start right before a stage change.
• Assuming a public charging station will be available mid-outage without checking whether it has off-grid backup.
• Sizing an existing home backup system for the house alone, then discovering it can't also carry EV charging load.
• Treating load shedding as an EV-specific problem rather than a household-wide planning task you're already managing for everything else.

Frequently asked questions

This guide is general information for South African motorists, not an installation or electrical recommendation. Installation costs, electrical requirements and load shedding schedules vary by home, province and provider. Always get a firm quote from a qualified, registered electrician before committing to a home charging or backup power setup.
