German auto supplier Mahle said on Monday it will roll out high-voltage charging technologies for the global electric vehicle aftermarket starting in 2025, aiming to strengthen its position as a provider of EV components beyond original manufacturing.
The company’s first products will include input filters available from October 2025 and onboard chargers by year-end, initially covering models from Renault, Peugeot, Citroën, DS and Opel. “Both components come directly from the original equipment manufacturing of the Mahle Group and fulfil the highest quality standards,” the company said, adding that additional high-voltage parts will follow in 2026.
Onboard chargers convert alternating current from the grid into direct current to store in EV batteries, while input filters protect systems from voltage spikes or unwanted signals during charging. “Like all other electrical and electronic components, high-voltage components are subject to wear and tear due to ageing, vibration, penetration of moisture, or superheating,” Mahle said. “This means their importance in the spare parts and service business will grow significantly.”
The expansion comes as reports of failures in Mahle chargers fitted to Stellantis vehicles have surfaced. Leipzig-based EV rental firm Nextmove said around one in three Opel Corsa-e models in its fleet were affected, with replacement costs exceeding €2,000 and long waiting times. Repair specialist EV Clinic has also documented repeated failures.
“By consistently expanding our product range for electric vehicles and plug-in hybrids, we are already positioning ourselves for our workshop partners in this growing market segment,” said Armin Messerer, head of product management and purchasing at Mahle Lifecycle and Mobility. “Workshops and end customers benefit from the strong position Mahle holds in original equipment … because the Group’s expertise is directly incorporated into the spare parts and service business in equal measure.”
At the IAA Mobility show in Munich, Mahle also showcased its TechPRO 2 diagnostic tool with AI functionality and its E-HEALTH-Charge battery diagnostic system.
