This document presents an analysis of the impact of electric vehicle (EV) penetration on South Africa's energy demand profile. It examines different EV charging models and their effects on the grid under various penetration rates ranging from 10% to 100%. While high EV penetration rates of 50-100% were found to increase peak energy demand, lower rates of 10-20% did not significantly impact the grid. The document also discusses South Africa's current energy supply and demand, cost considerations for consumers switching to EVs, limitations of EVs, and the potential for vehicle-to-grid technologies to help integrate higher shares of EVs by using batteries to store off-peak energy for sale during peak periods. It concludes that South Africa cannot currently accommodate

- 18. Limitations of EV’s Home Work PowerSupplies Requirements of an EV model for a grid integration Low power charging Battery swapping Quick charging batteries
- 19. V2G Technology Provide afuture for the energy crisis? Store off-peak cheap energy and sell at peak hours
- 20. Conclusions and Recommendations South Africa cannot integrate a large amount of EV penetration at present EV charging should be controlled and charging must be done in off-peak hours V2G technology should be adapted
