Handtmann presents battery system with up to 1.3 MWh

German supplier Handtmann Systemtechnik has unveiled a modular LFP battery system that can provide a capacity of up to 1.3 MWh. According to the manufacturer, it is particularly suitable for robust applications in heavy vehicles, ships and stationary energy storage systems.

Handtmann Systemtechnik describes its new battery system as flexibly scalable to meet individual customer requirements in terms of energy demand and installation space. The liquid-cooled solution utilises lithium iron phosphate cells, which are combined into modules of 13 kWh each. According to the manufacturer, these modules can then be combined to form battery sets with several megawatt hours.

“It is possible to connect up to 56 battery boxes – seven in series and eight in parallel. Individual configurations with up to 16 master boxes and a maximum capacity of 1.34-megawatt hours can be realised,’” the company explains in an accompanying press release. A minimum system consists of one master box and two battery boxes. The voltage options range up to a maximum of 1000 volts DC.

With the new battery system, Handtmann Systemtechnik aims to create a solution primarily for construction machinery, commercial vehicles, marine applications and stationary energy storage systems with high storage requirements.

The system has thus been tested on an in-house test bench in Biberach an der Riss, Germany, for its resistance to vibrations, fluctuating temperatures and cycle stability, among other things. An integrated safety concept should also include a ‘safety box’ that continuously monitors the system at cell, module and string level.

“When we developed this battery system, our focus was on the simple combination of different system configurations,” says Markus Michelberger, Business Development Manager at Handtmann. Handtmann Systemtechnik GmbH & Co.

KG was founded in 2003 and is thus one of the newest business units within the Handtmann Group. With around 150 employees, the unit sees itself as a technology and system partner for the automotive industry and supplies components for combustion engines (‘charging, exhaust gas routing, charge air routing and cooling as well as thermal management’) as well as for electric vehicles – such as high voltage storage housings and battery systems.
