Integrated EV Battery Test Systems Expand Capabilities
Webasto and Maccor collaborate to deliver comprehensive battery test and validation technologies for automotive and energy storage applications.

Webasto Power Test Systems (PTS), a division of Webasto Group, and Maccor Inc. have formed a strategic collaboration to offer integrated battery testing systems that span the full range of voltage scales relevant to electric vehicle (EV) and energy storage development. The partnership is intended to supply automotive manufacturers, laboratory research teams, and academic institutions with coherent test capabilities from individual cell cycling through high-voltage pack and drivetrain emulation.
The expansion of electrification in the automotive and energy sectors has increased the technical demands on battery validation infrastructures. As performance targets tighten and safety standards evolve, developers require testing platforms that can deliver reliable, scalable, and standards-compliant data across diverse use cases within the digital supply chain. The Webasto-Maccor collaboration aligns complementary areas of expertise—Maccor’s precision battery test systems and Webasto’s high-power, bidirectional testing technologies—to address these needs.
Under the agreement announced on December 8, 2025, the integrated solutions cover:
- Cell and Module Cycling: Precision control and measurement at the cell and module level, enabling controlled charge/discharge cycling for performance characterization and life-cycle studies.
- High-Voltage Pack Testing: Validation of complete battery packs under conditions that emulate real-world load profiles and thermal environments.
- Drivetrain Emulation: Simulating the electrical interactions between high-voltage battery systems and vehicle powertrains to assess performance under dynamic operating conditions.
Both companies design, manufacture, and provide service support for these systems within the United States. Domestic production is positioned as a factor in reducing lead times, enhancing supply chain stability, and improving responsiveness to technical support requests—considerations that are particularly relevant for rapid development cycles in automotive and aerospace applications.
Application Areas
The integrated testing portfolio supports multiple sectors where rigorous battery validation is critical. These include passenger and commercial vehicles, off-highway machinery, aerospace systems, and stationary energy storage. By enabling a seamless transition from low- to high-voltage test regimes, the collaboration aims to facilitate cross-domain research and development workflows and reduce the complexity typically associated with multi-vendor test environments.
Technical and Industry Implications
The interoperability of test platforms addresses a key challenge in battery research: ensuring that test data are comparable and actionable across different stages of development. Battery labs and OEM engineers frequently need to correlate cell performance with pack-level behavior under various electrical and thermal loads. Unified test systems can reduce integration overhead, minimize sources of measurement variability, and support data continuity throughout the validation process.
By combining established test technologies across the voltage and power spectrum, Webasto and Maccor aim to streamline the verification of battery architectures against regulatory standards and internal technical specifications. The focus on adaptable architectures also reflects broader trends in the automotive data ecosystem, where modular, scalable systems better accommodate iterative design cycles and complex duty-cycle simulations.
Positioning Within the Battery Test Market
While multiple vendors offer components for battery testing, fewer provide a coordinated portfolio that seamlessly spans cell level to high-voltage pack emulation. Objective comparisons in this segment are typically based on measurable criteria such as voltage range, current capacity, data acquisition resolution, test software flexibility, and integration overhead. In this context, the Webasto-Maccor partnership positions itself on the breadth of test coverage and the benefits of coordinated support and domestic manufacturing, rather than on proprietary performance claims.
