Electric vehicles (EVs) are celebrated for their relative simplicity compared to internal combustion engine (ICE) cars. However, this doesn’t make them immune to wear and tear. When key components like electric motors and high-voltage batteries fail, the replacement costs can be substantial, especially when sourcing new parts directly from the manufacturer. A new drive unit can run into thousands of dollars, while a battery pack replacement can easily exceed ten thousand. This is where the market for repairing and remanufacturing EV components comes into play, offering a more economical alternative. The trend of using remanufactured EV motors is gaining traction as EV adoption increases and the need for affordable repairs becomes more apparent.
Two established European component manufacturers, SEG Automotive and Fersa, are actively participating in this growing market by offering refurbished electric motors. Their collaboration provides a comprehensive solution: Fersa supplies new bearings for the motors, while SEG Automotive handles the rest of the remanufacturing process. This partnership leverages the expertise of both companies to deliver reliable and cost-effective alternatives to new EV motors.
| Company | Role | Expertise |
|---|---|---|
| SEG Automotive | Remanufacturing | Extensive experience in starters, alternators, and electric motors. |
| Fersa | Bearing Supplier | Specializes in high-quality bearings for automotive applications. |
Currently, their “Redrive” units are available for two popular EV models: the Renault Zoe city car and the first-generation Tesla Model S. For the Tesla Model S, SEG offers a remanufactured Large Drive Unit (LDU), a component known for potential failures due to coolant leakage. The rebuilt motor includes a coolant delete modification, simplifying the repair process with a plug-and-play design. Similarly, certain e-motors in the Renault Zoe are prone to failure over time, often occurring after the vehicle’s warranty has expired. This makes sourcing a new motor expensive and potentially time-consuming due to limited availability. The remanufactured EV motor for the Zoe serves as a direct replacement for part number 290103231R and is expected to be available by the end of June. The Tesla Model S replacement has been available since the previous year.
While SEG Automotive remains discreet about specific pricing details, they assure that their remanufactured drive units are approximately 30% more affordable than purchasing a new motor. To acquire a refurbished electric motor from SEG, customers need to go through an authorized service center. A notable benefit is the option to have a new motor installed first and then send the old unit back to SEG for remanufacturing. This process mirrors the remanufacturing of components like starter motors or alternators in ICE vehicles, an area where SEG Automotive has nearly a century of experience. Established in Stuttgart, Germany, SEG Automotive employs around 6,000 individuals across 14 global facilities and is recognized as a leading original equipment manufacturer (OEM) of starters, alternators, and 48-volt Boost Recuperation Machines (BRMs).
As electric vehicles become increasingly prevalent, solutions like remanufactured EV motors and aftermarket batteries will become more common. These developments will play a crucial role in extending the lifespan of EVs, ensuring that these vehicles remain on the road for many years to come. The availability of affordable, reliable remanufactured components is essential for the long-term sustainability of the EV market.
