Engineering Approach

Battery R&D and Application Engineering

Wiren connects battery selection and development with the requirements of the application. Voltage, capacity, current demand, operating environment and system interfaces provide the starting point for an engineering review.

Discuss the enclosure, BMS, communication and documentation needed for your project. Our OEM/ODM support begins with a clear technical brief.

Discuss Engineering Requirements

Assembly Requirements

Battery Layout and Connections

Battery configuration and enclosure design influence the assembly process. Review component layout, electrical connections and production checks against the requirements of the selected model and application.

Welding and Connection Quality

Process Compatibility

Connection design and welding processes affect battery assembly. Review the materials, joint requirements and inspection criteria for the selected design, with attention to repeatability and the integrity of electrical connections.

Design for Production

Design and Assembly Review

Product development needs to account for assembly, inspection and maintenance. Process planning connects the design requirements with the checks and documentation needed to support a consistent build.

Product Quality Planning

Quality Checks Matched to the Product

A useful quality plan identifies what is checked, how it is measured and which acceptance criteria apply. Cell and pack checks should relate to the agreed specification rather than a general equipment count.

For a project review, discuss the required measurements, records and supporting documents for the exact battery configuration.

Electrical Performance

Electrical Performance Checks

Voltage, current, capacity and internal resistance measurements help evaluate cells and packs against their specifications. Test conditions and measurement limits should be recorded so the results can be interpreted for the intended application.

Acceptance Criteria

Defined Acceptance Criteria

Incoming materials, assembly checks and finished-product evaluation should follow the agreed quality requirements. Clear criteria and records help identify deviations and support a focused technical review.

Discuss Your Battery Project

Share your application, voltage, capacity and project requirements. Let us help you evaluate a suitable battery solution.

Application Verification

Verification for the Intended Application

Verification begins with the conditions the battery is expected to encounter. Define the electrical, mechanical and environmental checks needed for the model, installation and destination market.

Request model-specific specifications and test documents. Confirm which certificate or report applies to the exact product and configuration.

Measurement Context

Measurements with Context

Electrical measurements are useful when the test setup, operating conditions and acceptance limits are clear. These details support comparisons between requirements and observed behavior during product evaluation.
Operating Conditions

Temperature, Load and Charging Conditions

Cell and pack evaluation should reflect the intended use. Temperature, load and charging conditions need to be defined so test results can be related to the application and its operating limits.
Development Feedback

Test Findings and Design Decisions

Testing provides information for design decisions. Review observations against the original requirements, identify changes that need assessment and document the basis for the next product evaluation.
Evidence Review

From Results to Decisions

Summarize what the test evidence establishes, the conditions it covers and any remaining questions. This helps project teams decide which configuration and further checks are relevant to their application.

Battery Safety and Reliability

Battery Packs and Systems

Battery Pack and System Review

Review protection functions, wiring and system interfaces against the application requirements. Mechanical and environmental assessments may cover vibration, shock, temperature, moisture and electromagnetic compatibility, according to the agreed verification plan.

Required tests and acceptance criteria depend on the product and market.

Cells

Cell Selection and Evaluation

Review cell specifications, operating limits and relevant test evidence for the application. Electrical, mechanical and environmental assessments should follow a defined test plan with appropriate methods and acceptance criteria.

Modules

Module Integration

Module evaluation connects the cells with the pack design. Review electrical connections, mechanical support, thermal conditions and the intended installation environment. Define any additional testing required for the complete battery system.
