Energy Storage Considerations
Battery storage is an essential component of any wind-based EV charging system, serving as the critical buffer between intermittent wind generation and the consistent power needs of an EV. Without the right storage, the variable nature of wind would make reliable charging impossible, potentially leaving vehicles unprepared when they're needed most.
Quality lithium battery systems from manufacturers like Tesla, GivEnergy, or Powervault provide the high discharge rates necessary for effective EV charging, with a minimum recommended capacity of 7kWh to support practical overnight charging sessions.
The battery management system (BMS) must be specifically designed to handle the variability of wind generation. During periods of excessive wind production, "dump loads" like water heaters or space heating systems can be incorporated into the system design to utilise surplus energy rather than wasting this valuable resource.
This approach to energy management means electricity generated by wind will be captured effectively and will be available on demand for EV charging, regardless of the current weather conditions.
Geographic Suitability Factors
Of course, it is very important to consider how your location will impact the amount of electricity produced:
Rural and coastal locations yield the best results with annual average wind speeds above 5m/s, like parts of Northern Scotland, Wales and Northern England
Urban and suburban areas are typically unsuitable because of the obstruction caused by buildings
Check the UK Wind Speed Database (NOABL) for site-specific data
Wind turbine EV charging is a substantial investment—there's no denying that—but can provide a reliable off-grid solution in suitable locations, particularly when combined with solar in a hybrid system to balance seasonal variability.
How Much Battery Storage Do You Need for Off-Grid EV Charging?
Battery storage systems form the crucial link between intermittent renewable energy generation and reliable EV charging, enabling true energy independence regardless of when the sun shines or wind blows.
