100 Electromobility is a central component of the energy transition. But for the e-car to prevail over other technologies, the range is crucial in addition to being environmentally friendly. The powerful lithium-ion batteries, which make e-mobility possible in the first place, are sensitive to deep discharge, overcharging and temperature peaks. Permanent monitoring of the battery by modern battery management systems, which continuously analyze its condition, is therefore necessary. The BMS make a decisive contribution to increasing the safety and durability of batteries. One of the manufacturers of this key technology for e-mobility is the Marquardt Group. The family company with headquarters in Rietheim-Weilheim in Baden-Württemberg stands for intelligent electronic and electromechanical systems and components. In the mid-1990s, Marquardt successfully entered the automotive segment on a grand scale with driver authorization systems. Today, the company is one of the world‘s leading manufacturers of mechatronic switching and control systems and is a partner to leading brands worldwide. The battery management systems from Marquardt for e-vehicles from various manu- Battery systems Optimum protection for high-voltage connectors Caps and plugs from Pöppelmann KAPSTO® protect highly sensitive battery management systems from Marquardt By Antje Bosche, Marketing Representative KAPSTO, Pöppelmann GmbH & Co. KG, Lohne The Marquardt Group manufactures battery management systems (BMS) for well-known vehicle manufacturers. Together with Pöppelmann KAPSTO® , the mechatronics specialist has developed individual protective elements made of plastic that reliably protect the high-voltage connectors and assembly openings of the BMS from contamination during storage and transport. The use of resource-saving recycling material ensures more sustainability.

Impurities can quickly have fatal consequences. For example, metallic particles can cause leakage currents, which can lead to malfunctions or even failures in the battery management system. We have to reliably protect our highly sensitive components from this.” For example, the main control unit that Marquardt manufactures for a premium vehicle manufacturer. This has several exposed high-voltage connectors and assembly accesses. In order to reliably cover the interfaces on the transport route to the customer, during storage and assembly, Marquardt relies on Pöppelmann KAPSTO®, a division of the plastics specialist Pöppelmann from Lohne. The division manufactures plastic protective elements that are produced using both injection molding and thermoforming processes and are used in industrial production. The plugs and caps prevent dirt from penetrating sensitive and function-critical components and are produced for a wide variety of target markets, e.g. for manufacturers and suppliers in the automotive industry, mechanical engineering, construction, electronics, hydraulics, aerospace, pneumatics and measurement, control and regulation technology … More resource-saving: recycling protective elements for HV applications made of PCR-PP bear the Blue Angel eco-label Image: © Pöppelmann
