The auxiliary harness is an auxiliary unit cable set and establishes the electrical connection between the high-voltage storage system and the auxiliary units, such as the heating, cooling or DC-DC converters. This is usually designed as a 2-pole connection in copper or aluminum. By integrating a Y/X-splice, more components can be integrated in a cost- and weight-efficient way. At LEONI, we have comprehensive system integration expertise based on specific customer requirements, making us your partner from design and development through to production.
