hofer powertrain

Advanced energy storage systems are pivotal to the success of tomorrow's mobility concepts. In order to ensure performance and cost efficiency of the entire drive train, also perfect interconnection of all individual components with the right energy storage system, depending on packaging space and weight is essential.

Off-the-shelf battery solutions ready for implementation into your vehicle concept

For effective recuperation or long driving ranges, we offer storage solutions based on different cell chemistries and cell formats for electric-only, plug-in and plug-in hybrid electric vehicles (PHEVs).

Solutions made to meet your special individual requirements

We are flexible when it comes to selecting the right cell technology to comply with all performance targets. Depending on the installation space and electrical requirements, we choose the most suitable cell type, irrespective of whether it is round, pouch or prismatic cell, to design the packaging optimally.

High-voltage storage systems – ranges make a big difference

Allowing rapid battery charging and longer lifetimes increases the widespread adoption of electric vehicles. To utilise the cells to their total capacity without reducing their durability simultaneously, we bring our extensive experience in thermal management into play. Furthermore, a sophisticated battery management system allows the monitoring of temperatures, voltages as well as charging and discharging processes, if necessary.
