Tesvolt, Samsung announce 5.26 MWh containerized battery

Tesvolt and the SDI battery manufacturing division of Samsung are offering a containerized energy storage product for municipal utilities and businesses.

The 5.26 MWh SBB 1.5 battery container features lithium nickel-cobalt-aluminum cells and German battery company Tesvolt said it will be compatible with various European inverters.

Tesvolt said the product’s municipal energy service concept and focus on cybersecurity and fire protection make it particularly suitable for city deployment.

With system data stored on German servers, Tesvolt CEO and Co-founder Daniel Hannemann said, “With larger battery systems, there is a risk that they will simply be shut down from other countries – for example, due to political conflicts.”

SBB 1.5’s software architecture is suitable for critical infrastructure and can protect municipal utilities and businesses from cyberattack.

Hannemann told pv magazine, “We see an acute need among municipal utilities and a high degree of compatibility with our solutions.”

Tesvolt monitors its battery packs down to cell level and maintains them, in the event of problems. The company’s Tesvolt Energy Controller Pro system, with its integrated controller for energy generation systems, keeps battery downtimes to a minimum, Tesvolt and Samsung SDI said.

Fire protection

A press release announcing the product stated Samsung SDI’s Enhanced Direct Injection fire safety system can detect overheating at battery cell level and automatically inject a coolant into affected battery modules. The cells are cooled by units with a noise level of 65 decibels.

The SBB 1.5 comes with an up-to-20-year warranty, from Tesvolt, and a performance guarantee for the operating life of the system, which is determined by the use and design of each installation. The manufacturers will guarantee more than 95% efficiency across charge and discharge cycles and at least 97% annual operating availability.

The manufacturers plan to start delivering SBB 1.5s from the second quarter of next year.
