HiVOLT HIGH-VOLTAGE LITHIUM STORAGE - secure + efficient battery storage solution of the next generation

Summary

The share of renewable energies such as wind and solar energy, which is fed into the electricity grids, is constantly increasing worldwide. This type of energy is highly volatile, and depending on the time of day and the weather they supply different amounts of energy. This causes two problems: 1. the energy grids are being burdened more and more – the blackout danger is growing! 2. The electricity is not available as required. That is why we need a highly flexible system in the future to compensate these fluctuations, to be able to guarantee a secure energy network and the provision of electricity on demand. Technologically, battery storages can provide this flexibility, but the price/performance ratio is still the biggest obstacle for a full market penetration.
HiVOLT describes a newly developed battery system based on high-voltage technology, which offers significant cost and efficiency advantages compared to conventional systems. Savings are achieved, among other things, by eliminating transformers and reducing system costs through lower currents. The impact of the technology is outstanding and has the potential to revolutionize the storage market. This is reflected in the outstanding economic efficiency of the high-voltage lithium storage. It is at least 33% higher compared to TESLA, BYD, E3DC and results from the following factors: Higher number of charge cycles (8,000), max. depth of discharge, higher energy efficiency (92%), low investment costs (570 €/kWh) and low system costs (50% reduction).
In SME Phase 2, the product is to be made ready for series. Serial production and commercialization are to be carried out. Commercial enterprises in i.a. Europe, East Asia and USA are to be reached (market size: 1.1 bn €). The high-voltage lithium storage (TRL7) was developed by TESVOLT GmbH. The global challenge of establishing renewable energies as the main pillar of energy supply can only be met with intelligent energy storages. TESVOLT -The energy storage experts.
