liflex NG

Sustainably reduce operating costs, increase efficiency and equipment availability

BENNING is one of the innovation and technology leaders in the field of lithium technology in Europe. Our experience over the past few years has shown that, in addition to system availability, it is above all the service life and the amount of energy that can be extracted during a charge/discharge cycle that are decisive for the success of the investment.

liflex NG is the next development stage of our batteries. It is an innovative, future-proof system from 24 V to 96 V.

Economical and smart

Smart energy management combines increasing resource availability and efficiency with a sustainable reduction in operating costs.

Compared to lead-acid batteries the following results when using a liflex NG energy system:

Approx. 30 % reduction in energy costs
No maintenance costs
No handling costs

Longer lifetime with Q-Leveling

liflex NG energy systems are using the patented Q-Leveling process.

The usable capacity of the battery is significantly increased compared to control via a BMS. The natural aging process of battery systems can be significantly slowed with the help of the BMS NG.

Future-proof innovative system

liflex NG is a modular battery system from 24 V to 96 V. This battery complies with DIN EN 1175 and is therefore future-proof.

The system consists of a master module 24 V/140 Ah and depending on voltage and capacity, if necessary, several slave modules of 24 V/140 Ah. The master module is equipped with a cell module and the BMS with Q-Leveling.

liflex NG types: Standard and Slim – Flexible installation

The liflex NG series is available in two module types: Standard and Slim. Both module types have the same capacity. The different housing sizes are achieved by different cell arrangement.

The systems/modules can be used both vertically and horizontally. This gives users added flexibility depending on the installation.

After only 2 years, the additional costs for the investment in a liflex NG energy system are compensated by the operating cost savings.

Approx. 30 % reduction in energy costs
No maintenance costs
No handling costs
Use of the battery over several vehicle lifetimes
No loading space costs

BMS NG – More efficient, safer and more economical with Q-Leveling

Comparision of the service life of a lithium ion battery (LFP 8S1P) equipped with a BMS or with a BMS plus Q-leveling — Here, we’ve compared the service life of a lithium ion battery (LFP 8S1P) equipped with a BMS or with a BMS plus Q-leveling. Our comparison illustrates the repercussion – on the whole system – of one cell’s loss of power. The loss is markedly reduced if the Q-leveling process is employed.

liflex NG energy systems are using the patented Q-Leveling process.

It not only measures and monitors the cell voltages, but also the capacity and fill level (SoC) of each individual cell.

Innovative algorithms compensate for the capacity differences between the individual cells by individually controlled charging currents already during the entire charging or discharging phases.

The usable capacity of the battery is significantly increased compared to control via a BMS. The natural aging process of battery systems can be significantly slowed with the help of the BMS NG.

This results in an increase in economic efficiency.

Short distances – Charging on site, no central charging station necessary

There are positive effects on the economic use of your equipment, e. g.:

Lower investment costs, as cargo holds with complex aeration / deaeration as well as central water filling are no longer required
Higher resource utilization
No exchange batteries necessary
Fast and intermediate charging capable with Boost Charge, intermediate charging possible at any time (25 % charge in 20 min, 100 % charge in 2 h)
