StoraXe PowerBooster

Description

StoraXe PowerBooster


Additional value due to optimal network use Quick charging directly in distribution networks
Quick charging stations with high capacity are an important component of the electromobility infrastructure. Sufficient power capacity for the connection of quick charging stations is not always available. The Grunblitz battery system, the PowerBooster, provides high capacity for the charging process while energy is recharged at the available network connection point at low power. This not only saves time, but also eliminates the need for elaborate medium-voltage systems, building cost subsidies or expensive network expansion.

Areas of application

  • PowerBooster for the supply of quick charging stations in
    limited-power distribution networks
  • “District storage” for local, physical network services such
    as peak capping, reactive power, etc.
  • “Current bank” as a district alternative to individual
    home storage systems for the optimisation of
    individual consumption
  • “Swarm solution” through the networking of many
    decentralised modules into powerful clusters, operated
    in a virtual power plant or in a superordinate energy
    management system
  • “Operating options” such as peak capping, frequency
    regulation, dynamic flexibility yield, reactive power, etc.
Additional value

  • Easy to transport
  • Installation outside directly at the site
  • Compact form with powerful technology
  • Integrated inverter with battery, energy
    management unit, security / firewall and
    communication unit via mobile radio
  • Direct AC connection to distribution networks at
    400 V level
  • Simple installation and set-up
  • Quick integration into virtual power plants and
    external IT systems
  • Open interfaces for individual adaptation in projects
Network services Decentralised flexibility
In addition to the function of the PowerBoosters, the decentralised battery systems can be installed as grid service stations nearly anywhere and outside directly at the site, and can be connected to 400 V distribution networks. Additional functions such as voltage stability, delay for optimum bandwidth utilisation of the network, frequency regulation, reactive power supply or peak capping are possible. It is for exactly these distribution networks which get temporarily overloaded due to renewable supply that flexible power solutions are highly in demand in order to better utilise existing networks. Via the Grunblitz Cloud Big-LinX, distributed storage systems can be monitored, safely coupled and integrated into superordinate systems and virtual power plants of the customers..

StoraXe® PowerBooster High capacity for EV-FastCharger for limited-power network connections
The electromobility sector is growing – otherwise it will not be possible to comply with future emission limits. Hundreds of thousands or even millions of e-vehicles need a charging infrastructure which can ensure supply of new energy in a reasonable amount of time.

Quick charging stations and vehicles can charge up with energy in even shorter times. The Grunblitz PowerBooster supplies the necessary power so the network connection does not become a bottleneck, and eliminates the need to expand the network, saving a huge amount of time and money.

While the PowerBooster charges slowly and with limited capacity, it can transfer its energy to the vehicle in a very short amount of time.

Example for the connection of the PowerBooster in a charging infrastructure

  • Compact construction
  • Installation outside directly at the site
  • Direct AC connection to distribution networks at 400 V level
  • Recharging with reduced grid connection power
  • Suitable for vehicle quick charging station with high charging power
PowerBooster in the charging infrastructure
Utilise high charging capacity despite limited network capacity. Fill up with cheap energy with limited capacity and systematically output at high capacity.
PowerBooster For the provision of network services
Whether networked or in individual cases, reactive power, frequency regulation, peak capping, etc. can be provided anywhere.
Grid services station As district storage systems
Efficient and a service to the community. District storage systems as an alternative to home storage systems with added value in use.
Peak load capping
Reduce operating energy costs by cutting load peaks.
Emergency power supply
Provision of power in the event of an interruption of the mains supply.
Primary control power
For the power supply to work everywhere, the grid frequency must always be constant.
Microgrid (Off-Grid)
For a self-sufficient power supply independent of the higher-level power grid.
EV charging
At limited power grid for optimal charging infrastructure.

Software

For centralized and decentralized energy management
From the OFFLINE version of a decentralized single system to complex ONLINE-coupled interconnection systems. With the Grunblitz platform Big-LinX® Energy, the energy management system is scalable for every application.
