Grid stability & peak shaving: How EV chargers secure the energy transition

The mobility transition presents city planners, businesses, and grid operators with a massive challenge: How can we meet the growing demand for ultra-fast energy without overloading the existing power grid? The answer lies in the intelligence of the infrastructure.

JOLT is revolutionising this sector with battery-buffered charging solutions that don’t just charge vehicles, but actively contribute to grid stability through EV chargers. Let’s define the buzzwords and clarify our plans:

The challenge: Peak loads in urban areas

Space is limited in modern cities, and the mains grid is often at its limit. When several electric vehicles want to charge ultra-fast at the same time, enormous peak loads occur. Conventional systems often require expensive and time-consuming grid extensions for this. This is where the principle of peak shaving in e-mobility comes in.

What is peak shaving?

Peak shaving refers to smoothing out peak loads in electricity consumption. Instead of drawing the full charging power directly from the low voltage grid, intelligent systems use integrated battery storage. These storage units are charged continuously and slowly when the grid load is low, and deliver the energy to the vehicle in a flash when needed.

Intelligent load management for high power chargers

Efficient load management for high power chargers is the backbone of a future-proof charging infrastructure. JOLT acts not only as a charge point operator (CPO), but as a technological partner for municipalities and businesses.

• Relieving the low voltage grid: Thanks to the integrated 200 kWh storage in our stations, no costly grid extension is required.
• Real-time optimisation: Our networks act as intelligent energy storage systems that balance the supply and demand of electricity from renewable sources in real-time.
• System-friendly capabilities: JOLT’s infrastructure supports functions like grid frequency stabilisation and load management, which massively increases overall grid stability through EV chargers.

Why battery-buffered charging solutions are the future

For site partners like petrol stations, supermarkets, or quick service restaurants (QSR), JOLT’s technology offers decisive advantages. Because our stations, such as the MerlinOne or the ChargeBox, have internal buffers, they can offer ultra-fast charging with up to 320 kW, even if the local grid connection is actually too weak.

Benefits for site partners:

• Fast set-up: Without lengthy construction work for new cables, our systems are ready for use in a very short time.
• Cost efficiency: You avoid high investment costs in grid infrastructure, as JOLT handles the planning, financing, and operation.
• Sustainability: We promote the use of volatile renewable energies by storing electricity when it is in abundance.

JOLT: Your partner for urban mobility

We at JOLT believe in the power of change. Our goal is to build a comprehensive urban charging network of 3,600 chargers by the year 2028 to ensure seamless connectivity and sustainable transportation for all city residents. In doing so, we rely on transparency, reliability, and technological innovation.

Our solutions offer more than just power: They are an active contribution to the decarbonisation of our cities and the securing of the energy infrastructure. By combining ultra-fast charging technology with smart peak shaving in e-mobility, we make the switch to electric vehicles attractive and safe for everyone involved.

Conclusion: The city of tomorrow charges today

The integration of load management for high power chargers and battery-buffered charging solutions is not a luxury, but a necessity for the success of the mobility transition. JOLT delivers the technology needed today to relieve the grids of tomorrow.
