The innovative VENSYS VENSTORE LION storage technology is the final step towards independent power supply. Based on the most progressive lithium-ion technology, characterised by multi-megawatt performance reserves and a higher temperature range, the VENSTORE LION has a multitude of application options. VENSYS storage solutions stand for intelligent and future-proof technology on a global standard.

The VENSTORE Lion storage system is available in an indoor and outdoor cabinet. Thanks to its multiple application cases this system provided a high degree of flexibility.

 

The Highlights: POWERFUL PROFITABLE EFFICIENT SAFE ROBUST SCALABLE FUTURE-PROOF

  • Modular design and innovative IT management provide high scalability
  • Compact outdoor cabinet for flexibility and low overhead costs
  • Excellent safety standard thanks to safety devices and optimal monitoring
  • Innovative Battery Management System
  • Cell technology to highest industry standards
  • Capacities up to 115k kWh per cabinet
  • Optimised for wide climate range
  • Connecting to VENSYS systems without additional inverters

VENSTORE LION Application cases

 

Self-consumption optimisation

The amount of energy gained from volatile energy producers is often not in line with own energy needs. With VENSTORE Lion, excess energy can be stored and provided at a different point in time. Supply optimisations can also be enhanced.

Feed-in limitation

If the system performance of the generating facilities happens to be higher than the power supply, the VENSTORE storage solution can store the excess energy and release it at a desired point in time.

Power supply network

Load peaks in the supply network can be compensated for with this solution, thereby avoiding a network expansion and minimising transfer loads from medium- voltage transformers.

Frequency control

The VENCON inverter family can react quickly to either over-frequency or under-frequency, so that the VENSYS system solution can support the grid frequency.

Provision of energy control

In order to trap excess production, the network storage solution VENSTORE can temporarily store this energy. In so doing, no regenerative power generation must be reduced or switched off completely. Thus, the proportion of environmentally friendly electricity can be increased in the network without necessity to set up additional generating plants.

 

The BMS supplies the following information:

 

Cell voltage

(maximum/minimum/average value)

Internal resistance

(maximum/minimum/average value)

Temperature

Each drawer (maximum/minimum)

Number of cycles

For each cell

State of charge

SOC

State of battery health

SOH

Strom

In order to guarantee the durability and highest quality standards, each lithium cell is tested on an in-house VENSYS test stand.
