The situation

50five and ALLSAFE operate fast chargers at over 50 locations with limited grid connections. Batteries support charging, but largely sit idle outside peak hours while they could be generating value in electricity markets.

Key challenges

Limited grid capacity at multiple locations

The client was dealing with multiple systems, each optimizing its own objective. A trader managing the battery without an FMS, an EMS monitoring the connection. No one had an overall view.

Guarantee charging sessions while the battery also trades

No connectable Fleet Management System or Transport Management System was available. Nevertheless, vehicles needed to be charged reliably and on time, with varying priorities per charging station or vehicle.

Maximize value from a distributed portfolio of locations

The client wanted to benefit from favorable electricity prices and ERE trading, but not at the expense of operations. The battery needed to be deployed smartly without ever compromising charging reliability.

"As soon as you add a battery and also want to trade on the energy market, you suddenly have three parties all wanting different things from the same connection. Zympler is the only one that sees this as a single, integrated whole."

and Zympler

Predictive Location Management

Daily, Zympler analyzes the historical charging profile per location and models expected peaks, ensuring that the optimal trading strategy always aligns with the actual battery availability.

Guaranteed Priority for Charging Sessions

Advanced algorithms ensure that charging sessions always receive 100% priority. Trading only occurs within the margins that predictions qualify as safe.

Virtual Power Portfolio

All batteries and solar panels at 50five & ALLSAFE locations are bundled and offered to the energy supplier. This combined portfolio generates more revenue across all markets than individual systems could ever reactively achieve.

Why are Zympler and 50five & ALLSAFE a good match?

Zympler ensures that the batteries of 50five & ALLSAFE not only relieve the grid but also actively generate daily revenue, without ever jeopardizing a single charging session.
This makes Zympler not an infrastructure cost, but a direct contributor to the business model of 50five & ALLSAFE.

Zympler enables Nagel to profit from hyper-local smart charging.
