German supplier Handtmann Systemtechnik has introduced a modular lithium iron phosphate (LFP) battery system designed for use in heavy vehicles, marine applications, and stationary energy storage systems. The scalable system offers a capacity of up to 1.3 MWh, catering to diverse customer needs in energy storage and installation space.
The liquid-cooled system utilizes 13 kWh modules that can be configured to create battery sets with capacities reaching several megawatt hours. According to Handtmann, the system supports up to 56 battery boxes, arranged in configurations of up to 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 realized,” the company stated. The system supports voltages of up to 1000 volts DC, with a minimum setup requiring one master box and two battery boxes.
Handtmann emphasizes the system’s durability and adaptability for demanding environments. The battery system has undergone extensive testing at the company’s facility in Biberach an der Riss, Germany, including evaluations of its resistance to vibrations, extreme temperatures, and cycle stability. A built-in safety box monitors the system at cell, module, and string levels to enhance operational safety.
“When we developed this battery system, our focus was on the simple combination of different system configurations,” said Markus Michelberger, Business Development Manager at Handtmann.
Founded in 2003, Handtmann Systemtechnik is a division of the Handtmann Group, employing around 150 people. It serves as a technology partner for the automotive industry, supplying components for both internal combustion and electric vehicles, including battery systems and high-voltage storage housings.
