Charging without grid extensions

Charging without a high-capacity grid connection: Ultra-fast charging even on a weak grid

The transition to electric mobility is in full swing. At JOLT Energy, we are actively driving this change by bringing ultra-fast charging to urban areas. Reliable, widely available fast-charging infrastructure is essential to advancing the energy and mobility transition.

But companies and site operators often face a huge challenge: the local electricity grid simply does not have enough capacity for high-power charging (HPC).

This is where JOLT comes in with a revolutionary solution!

Why conventional grid expansion is often an obstacle

When companies want to offer customers ultra-fast EV charging, local grid capacity often gets in the way. Providing hundreds of kilowatts of charging power normally requires time-consuming and costly upgrades to the grid connection. Our innovative charging solutions overcome precisely this hurdle.

We have the solution: Our charging stations feature integrated battery storage, allowing seamless connection to the standard low-voltage grid without costly, time-consuming upgrades. Our approach to charging without a dedicated grid connection or complex grid upgrades makes installation fast, efficient and economical.

Innovative technology: Charging without a high-capacity grid connection

Our approach is designed to meet growing demand for ultra-fast charging while supporting the global transition in the energy and mobility sectors. By using our state-of-the-art charging and battery technologies, our network functions as an intelligent energy storage system.

It balances the supply of and demand for electricity from renewable sources in real time. This not only stabilizes the power grid but also creates additional sources of revenue.

Become a site partner and build a charging station despite a weak grid

As a site partner, you can provide charging infrastructure without having to manage the complexities of a charging business. At JOLT, we plan, finance and operate premium chargers at your site – you simply provide the space and we take care of the rest.

Benefit from a partnership model tailored precisely to your needs:

  • No grid upgrade needed: Battery storage lets you avoid lengthy construction work on the electricity network.
  • No investment costs: As a partner, you do not need to make any upfront financial investment.
  • Additional sources of income: Benefit from extra revenue and increase your turnover.
  • Highly space-efficient: Our solutions require very little space.
  • Focus on your core business: Because we operate the infrastructure, you face no operational risks and can concentrate entirely on your own business.
  • Attract new customers: Increase customer satisfaction and clearly stand out from the competition.

By the way, installing charging infrastructure is also ideal for commercial property owners seeking to meet ESG requirements and increase tenant satisfaction. We offer the following charging solutions:

MerlinOne: maximum flexibility for urban spaces

Our MerlinOne charger is a prime example of this technology. The MerlinOne is a high-power charger with an impressive output of 300 kW (2 × 150 kW).

  • It offers charging ten times faster than conventional AC chargers.
  • Thanks to its integrated battery storage and mobile design, the MerlinOne revolutionizes charging infrastructure by enabling rapid deployment without extensive construction work.
  • Particularly noteworthy for charging without a grid connection: island mode allows chargers to be placed at strategic locations independently of existing electrical infrastructure.
  • The integrated 200 kWh battery delivers enough energy for 200 km of range in just a few minutes.
  • Current advertising can quickly be displayed on the HD screen, attracting more customers.

ChargeBox: compact power up to 320 kW

Another outstanding system solution for battery-buffered, ultra-fast charging is the ChargeBox from ADS-TEC Energy.

  • The ChargeBox is the most compact and efficient solution in its class, charging at up to 320 kW completely independently of grid infrastructure constraints.
  • Flexible placement allows for up to 300 metres between the grid connection and the actual charging point.
  • The system consists of a ChargeBox Booster and a ChargeBox Dispenser.

Conclusion: Charging without a heavy-duty grid connection made easy

Charging without a grid connection, or ultra-fast charging at sites with weak grid connections, is no longer a thing of the future thanks to JOLT. We make life easier for electric-car drivers and enable companies to take part in the mobility transition without financial barriers. The result will be a sustainable, fully electric transport system that works for all city residents and businesses.
