HELLA develops two new battery systems for mild hybrids

Lighting technology and electronics company HELLA has developed two new battery systems for mild hybrids. The two systems, the Dual Voltage Battery Management System and PowerPack 48 Volt, allow for savings of five to six grams of CO2 per kilometer, according to the company.

Designed for compact and mid-range vehicles, the Dual Voltage Battery Management System enables the conversion of ICE vehicles to mild hybrids. The system combines elements such as a 48 V battery, 12 V battery, and DC-DC converter, and uses Li-ion battery cells, eliminating the need for a lead-acid battery.

The PowerPack 48 V is designed for higher power rating classes and combines a 48 V battery and DC-DC converter. The system allows for hybrid functions, including recuperation, in which energy is recovered while braking, and active coasting, in which the ICE is turned off while driving.

Björn Twiehaus, Head of Product Center Energy Management at HELLA, said “Hybridization with 48 V is particularly promising because it requires only minor intervention in the vehicle architecture while also offering efficient energy recovery methods and improved energy efficiency.”
