Forvia Hella, an international automotive supplier, announced the expansion of its power electronics portfolio for electric vehicles with the introduction of its new High Voltage PowerBox (HV PowerBox). The HV PowerBox, which is set to enter series production by 2027, features a high-power density of over 3 kW per liter, allowing for a more compact design that does not compromise on power. This design contributes to a reduction in weight and increases overall efficiency with a remarkable efficiency rate of 97%. This efficiency is anticipated to result in lower electricity costs for charging.
This innovative product integrates a high-voltage converter and an onboard charger into a single unit, with the possibility of incorporating a battery management system (BMS) and an intelligent Power Distribution Module (iPDM). The HV PowerBox aims to enhance the charging speed, safety and efficiency of EVs, reflecting Forvia Hella's commitment to advancing e-mobility.
Jörg Weisgerber, managing director of Electronics at Forvia Hella, highlighted the importance of efficient and swift charging processes for the broader adoption of EVs. The design of the HV PowerBox also focuses on cost-effectiveness, reducing material, logistics and development expenses, and simplifying vehicle integration. Innovations in housing, heating, cooling and design are directed toward mass production, which could lead to a 20% to 25% decrease in weight. The HV PowerBox can accommodate essential e-mobility components, including a high-voltage BMS and e-fuses, among others.
With over 15 years of success in the power electronics sector, Forvia Hella produces approximately 3 million 48-V/12-V voltage converters annually and is preparing to launch its first high-voltage converter in series production in 2025. Weisgerber emphasized the company's leadership and achievements in quality, reliability and automation in power electronics, noting that the HV PowerBox represents an expansion of Forvia Hella's expertise into crucial components for electromobility and autonomous driving.
