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.
