In the world of electric vehicles, the quest for greener, more sustainable charging solutions is more crucial than ever. Imagine pulling up to a charging station, where the energy fueling your EV comes directly from the sun above you - even at night. This isn't a vision of the future; it's happening right now with a combination of DC chargers and energy storage - now packaged in an integrated system.
Nice to meet you: Ultra-fast DC charger with integrated energy storage system
Let's take a closer look at this innovative ultra-fast charging system and how it is changing the game. Picture this: It's a sunny afternoon, and solar panels are working at their peak, absorbing every ray of sunlight. Instead of letting this abundant energy go to waste, a DC charger with an integrated 200kWh energy storage system captures it, storing this solar power for later use. This means that even during the bustling evening rush, when everyone's heading home and plugging in their EVs, the stored solar energy ensures that charging is readily available, efficient, and, most importantly, green.

The not-so-sunny side of solar production at public charging locations
While the idea of providing public charging that is 100% green and produced on-site with solar panels sounds like the perfect fit, the reality is slightly more challenging. The demand curves of each charging site vary based on the type of drivers in the area - on average the demand curves of solar production and ultra-fast charging do not match perfectly (Source: Researchgate). Now, this does not mean that solar production couldn't generate some of the EV charging energy - but to reach 100% requires something else: storage.
The key to unlocking 100% renewable public charging: Energy storage systems
Maximizing solar production at public EV charging locations through the integration of energy storage systems involves capturing surplus solar energy during daylight hours and deploying it during evening peak demand periods. By coupling solar installations with energy storage, charging stations can reduce reliance on non-renewable grid electricity, promote clean energy use, and potentially lower electricity costs. Effective management of energy storage systems, facilitated by advanced energy management systems, ensures efficient utilization of solar power while meeting the charging needs of electric vehicles. This integrated approach signifies a significant step towards a sustainable future in transportation and energy.
A Win-Win: Financial Incentives for Charge Point Owners
For Charge Point Owners (CPOs), the adoption of these solar-powered chargers isn't just good for the planet—it's good for business. Here's how:
Faster ROI on Solar Investments:Â By optimizing solar energy for EV charging, CPOs see a quicker return on their investment in solar panels.
Savings on Grid Fees:Â Charging EVs with solar energy during peak times means less reliance on the grid and, consequently, lower grid fees.
Reduced Electricity Costs:Â Using solar power primarily cuts down on electricity bills, making the operation more cost-effective.
