Multi-level energy storage system for Bischof Lagerhaus Ag
Bischof Lagerhaus AG is a subsidiary of Bischof Lebensmittellogistik in Feldkirch, located in Sennwald, Switzerland. In 2012, the 54,000 m2 site became a fully automated multi-temperature center and distribution platform for Switzerland. It serves as a warehouse for a total of 10,000 frozen pallet spaces and 12,000 multi-temperature pallet spaces (fresh & dry storage).
Our services
In times of energy transition towards a more sustainable and greener future, innovative energy storage solutions are increasingly coming into focus. With a new inverter technology, we are giving used and leftover car batteries from electric or hybrid vehicles a second life: in our innovative energy storage system for industry and commerce.
Store energy with used batteries
A 20-foot container complements the company building of Otto Bischof Lagerhaus AG in neighboring Switzerland (Sennwald). The container stores energy – to be precise, it has a storage capacity of around 1.6 MWh.
The purpose of the industrial storage system is to optimize self-consumption. The energy is stored using second-life modules from the automotive industry. This makes it the first commercialized Second-life energy storage on the market.
Project details:
- Storage capacity: 1,569 kWh
- Storage capacity [usable]: 1,255 kWh
- Extension: approx. 523 kWh in the same container
- Location: Sennwald, Switzerland
- Monitoring: cell voltage, cell temperature, current and passive balancing
- Purpose: Self-consumption optimization and emergency power function
- Degree of self-sufficiency: ~2 days
Self-consumption optimization
The aim is to optimize their own electricity consumption with an energy storage system. The electricity is also produced by a photovoltaic system which, once extended, will provide more than 1,800 kWp for electricity production. A 20-foot container with automatic cooling is used for storage. The container contains 12 racks with a total of 144 modules. A further rack is used for the control system and electronics. Each individual battery module is equipped with an inverter and a battery management system. All modules therefore function independently and can be replaced individually in the event of a failure without interfering with the overall system. The storage system can be expanded with two further systems and thus equipped with an additional 0.5 MWh. In the future, the system will also be expanded to include an emergency power function so that the energy supply from the storage system can be used in the event of a power failure.
All-in complete system
The container is fitted with the individual modules on site at e.battery systems. The container is delivered fully equipped with battery modules. The power storage unit is positioned and electrically installed on site in Sennwald.
The system is based on a 67.5 kW inverter. Additional power can be added by expanding the system with additional modules and containers.
The storage of the future.
Energy storage or better known as Energy Storage Systems are the future of efficient energy storage and energy supply. Basically, the system is simple and quickly explained. Energy can be stored via the power grid or preferably via alternative power sources, such as electricity from photovoltaics, and then used again as required.
But why do we actually want to store energy? By storing energy, we can generate power independently of the grid and therefore have access to this energy even in the event of an outage. We can also optimize our own energy consumption by capping peak loads.
The complete control and monitoring of energy consumption, energy sources and the energy storage system works simply via our energy management system.
