Hofer Powertrain develops fast recharging battery technology for EVs

German powertrain tech firm Hofer Powertrain has announced the launch of its advanced EV battery technology – the 'ULTEVATE Ultra' battery module. The company claims the technology as a significant leap in the realm of ultra-fast charging, setting new industry benchmarks in the global EV tech industry. 

The technology enables rapid charging that can enabled a state of charge (SOC) of 5-85 percent in just five minutes and to 100 percent in eight minutes. A remarkable advantage of this system is that it generates very low heat and does not require active cooling despite its high charging power, the developer claims, making it more efficient and less maintenance-intensive. 

With a charging current of up to 1140 amperes and a high charging power of over 1 MW at the vehicle level, the module represents a revolutionary step, hofer powertrain adds. "We always strive for the optimal power-to-energy ratio for our customer projects. Our goal is to continuously increase the energy content of a traction battery while simultaneously increasing the charging power," commented Gerold Sluka, Managing Director of the Battery Development division at hofer powertrain.

The company considers MW charging stations as a paradigm shift that will become more common in the coming years. As one of the fastest rechargeable battery technology for BEVs, 'ULTEVATE Ultra' offers OEMs the opportunity to bring the most innovative EV drive and battery solutions to mass production much faster, it says.

Prof. Dr. Kai André Boehm, battery expert at hofer powertrain, said, "We focus on efficient, robust, and safe solutions to maximize technical progress. Our development foresight is based on the continuous exploration of new cell chemistries and cell manufacturers, in order to offer our customers future-proof technologies that can be specifically transferred into series in line with customer timelines."

hofer powertrain claims strong experience in developing similar technologies that enable charging of batteries in less than ten minutes. These technologies are already successfully supporting customer projects in the area of fast-charging and becoming increasingly popular. The new development promises to fundamentally change the way we use electric vehicles, it adds.
