It’s a pivotal moment for the EV industry in South Africa: Our charging network is rapidly expanding, and so is the range of models and price points.
One of the many benefits of EV’s is the low maintenance cost compared to combustion engine vehicles. But your EV battery still needs some special consideration, and a few simple charging habits will protect it and keep your EV running smoothly for years.
So this is how to maximise your EV battery life – whether you’re charging at home or at a public charging station.
Charging at Home
Charging at home is one of the biggest perks of owning an EV. You plug in, relax, and wake up ready to go. But how and when you charge matters more than you might think.
- 80% is more than enough
Battery technology has improved significantly over the past couple of years, so regularly charging to full capacity no longer has such a negative impact on a battery’s longevity. Still, a good rule of thumb for optimum battery performance is to keep your battery charged between 20% and 80%, and to save the 100% charges for longer trips.
- Choose slower, steadier charging
Home chargers typically use AC power, which charges more slowly than public DC fast chargers — and that’s a good thing. Slower charging produces less heat, helping your battery last longer. If your vehicle allows it, schedule charging during off-peak hours or when your solar power is most active.
- Keep your charger and car cool
Extreme heat is one of a battery’s biggest enemies. If possible, charge your EV in a shaded area or garage, and make sure your charger has good airflow and ventilation.
Charging at Public Stations
South Africa’s network of EV chargers is expanding fast, and you’ll now find stations at shopping centres, petrol stations and along key highways. Understanding how to use these chargers will help keep your battery healthy.
- Understand charger types and speeds
Public chargers generally come in two forms:
- AC chargers (typically 7–22 kW) — slower, gentler on your battery, perfect for longer stops.
- DC fast-chargers (50–200+ kW) — ideal for quick top-ups but generate more heat in the battery.
A good rule of thumb: use AC chargers for everyday top-ups and reserve DC fast-charging for long trips or when you’re short on time.
- Stop at 80% when possible
Just like charging at home, it’s good practice to charge to 80% at a public station, unless you need the full range. And the person waiting next in line will love you for it!
- Use your EV app for insights
Most South African charging networks now link to apps that show live charging data, temperature readings and usage history. Keep an eye on these stats to understand how your habits affect battery health.
- Keep connectors clean and dry
Before plugging in, take a second to wipe the charging cable and port. Removing dust or moisture prevents electrical resistance and ensures a smooth, efficient charge every time.
Your EV battery is designed to last, and with good charging habits, it will.
Charge smarter. Live lighter. Drive further with black tower.
