Tesvolt and Samsung unveil new high-voltage storage system

The German storage system provider Tesvolt and Korean industrial group Samsung will introduce a new high-voltage storage system this week at the Energy Storage trade show in Düsseldorf, Germany.

According to Tesvolt, the new battery is long-lasting, efficient and safe. The battery utilizes new prismatic lithium cells based on nickel manganese cobalt oxide developed by Samsung SDI, and a new management system that ensures active cell balancing between all cells, even between the different battery modules.

“The new lithium cells from Samsung SDI have enormously high energy density,” said Simon Schandert, Director of Engineering at Tesvolt. The German car maker BMW has recently adopted these cells for its electric vehicles.

“The new Tesvolt storage system,” – say the company in a press release, – “can complete around 6,000 full charge cycles with a depth of discharge of 100%, which means that the entire battery capacity can be used. The storage system functions just as well with a low voltage of 48 volts as with a high voltage of 1,000 volts for stationary commercial and industrial applications.”

Tesvolt also added that the device disposes of integrated cell safety device and overcharge protection. This mitigates fire risks, while a pressure relief valve additionally ensures that there is no danger of explosion. Furthermore, the company said that its smart battery management system monitors the state of each individual cell to prevent damage at an early stage.

The new battery storage system is available in all sizes from 4.8 kWh up to power stations with multiple MWh.
