Charging an Electric Vehicle in the Era of Load Shedding
As electric vehicles (EVs) become increasingly popular in South Africa, concerns about their functionality during load shedding have emerged. However, keeping an EV charged under such conditions is simpler than many assume, primarily due to strategic charging habits and technological efficiencies.
Understanding Charging Times
The time it takes to charge an EV depends on several factors, such as the charger’s power output and the vehicle’s charging capacity. For instance, charging from empty to full at home can take approximately 10 hours, which has led to concerns during load shedding events.
However, most EV owners do not charge from empty to full. Rather, they opt for charging whenever possible, ideally at home where electricity tariffs are lower. This approach not only saves money but also aids the long-term health of the battery.
MyBroadband’s Real-World Experience
MyBroadband has tested EVs under extreme load shedding conditions and found they are quite manageable. For example, using a slow, 3kW portable charger during stage 6 load shedding still allowed them to maintain a full charge for daily commutes.
Crunching the Numbers: Practical Charging Strategies
Let’s delve into some figures to illustrate this further. The average EV consumes about 19kWh per 100 kilometers. With an average daily commute of 43km, an EV user would consume roughly 8.17kWh daily. Even during stage 8 load shedding, a 3.7kW charger could replenish this over two hours. The situation improves further with a 7.4kW charger, typically available in urban areas.
Overnight charging is feasible even during stage 8 load shedding. A household could feasibly achieve up to 150–200km of daily travel, depending on their charger’s capacity and power availability.
Frequently Asked Questions
Will load shedding affect my EV usability?
No, not significantly. Strategic charging practices and varied charger power levels ensure usability.
Is public charging more expensive than at-home charging?
Yes, typically. Charging at home tends to be cheaper due to lower energy tariffs.
How can I maximize my EV’s range during load shedding?
Charge whenever possible, use slow chargers overnight, and plan commutes efficiently.
Tips for EV Owners
Did you know? Charging in shorter spurts at home is more battery-friendly than a single long charging session.
What Does the Future Hold?
The future of EVs in South Africa looks promising, with advancements in charging technology and smart energy management systems expected to further ease concerns around load shedding. Government incentives and increasing charging infrastructure will likely encourage more widespread EV adoption.
