电动汽车电池的测量和分析

Battery Structural Testing

The battery is among the largest and heaviest part of modern electric vehicles. Overall lightweight design and flexible packaging need to be balanced. Optimal weight, structural durability, and overall life-cycle estimation are key parameters that need to be validated before the start of production. HBK is among the leading supplier of seamless measurement chains not only for measurement and physical structural durability testing, but also virtual structural durability testing and lifetime estimation.

From Sensors to Qualified Data

Our end-to-end solution helps you validate and optimize HV battery storage – thermally, electrically, and mechanically.

Thermal Analysis of High-voltage Batteries

Computer-based thermal simulation done by Computational Fluid Dynamics (CFD) models serves as an important step towards optimal system design. Real physical testing, however, is still required, as simulation considers not all architectures, integration aspects or parameters.

While battery performance is monitored in climate chambers, important data is gathered. In this environmental and performance test routine, the impact of extreme temperatures can be investigated. It becomes apparent which cooling systems are the best to reach customer use and performance targets. The load case can be scaled and cover all integration levels − from component testing to the entire drivetrain − to optimize the entire system and thermal management before starting production and series.
