Vehicle Energy Management Testing

Maximising vehicle range requires understanding energy consumption across auxiliary systems – not just the powertrain. HBK provides a single, synchronised measurement system that captures every source of energy loss under realistic, dynamic drive cycles, giving engineers a complete and auditable view of vehicle power distribution.

Map every source of vehicle energy consumption - from the battery and motors to HVAC, lighting, and infotainment.

Unify Data 

Capture and synchronise high-channel-count power, torque, temperature, and CAN bus data in a single, unified system.

Optimise Range with Confidence 

Transparent, auditable data from dynamic drive cycles helps engineers make confident decisions that genuinely extend vehicle range.

Assess Vehicle Power Distribution Everywhere - Not Just the Powertrain

Energy consumed by auxiliary systems like HVAC, lighting, and infotainment directly impacts how far an electric vehicle can travel. To maximise EV range and gain a competitive edge, engineers must have a complete understanding of energy consumption. 

HBK’s EV range testing solution is designed to address two key challenges that make evaluating and addressing energy consumption difficult. 

The Challenge 

The HBK Solution 

Engineers must manually synchronise power, mechanical, and bus signals from dozens of components. This is challenging – but, without synchronisation, it’s hard to understand cause-and-effect relationships between systems. HBK’s Genesis HighSpeed system provides a single mainframe with high channel counts for power, mechanical sensors, and bus data. This delivers a perfectly time-aligned, comprehensive dataset.
Conventional power analysers lose accuracy during the rapid speed and load changes typical of dynamic drive cycles like WLTP and CLTC.HBK’s advanced ‘Cycle Detect’ feature delivers accurate, real-time power and efficiency calculations even during rapid changes in frequency and load, giving you a true understanding of dynamic losses during CLTC and WLTP testing.

A Complete Measurement Chain: Accurate Energy Flow Analysis at Every Stage

Capture precise electrical and mechanical signals from every energy-consuming component across the vehicle.

  • High density of input cards (GN310B/Remote Probes for power, GN610B for voltage, bridge, and temperature) capture signals from the battery, inverters, motors, and auxiliary components like HVAC and pumps.

Correlate physical measurements with the vehicle's digital control signals and diagnostic information.

  • Genesis HighSpeed Mainframe (GEN7tB or GEN17tB) as the core of your test

  • Integrate CAN/CAN-FD bus interfaces to correlate physical measurements with the vehicle's digital control signals

Turn complex, high-channel-count data into a clear, live picture of vehicle energy consumption and flow. 

  • Perception software for real-time visualisation of vehicle energy flow

  • A powerful formula editor for transparent, customisable calculations, event triggering, and drive cycle segmentation, turning complex data into clear, actionable insights.

Key Areas of Application

EV/HEV Range and Certification Testing

Perform official range certification tests (WLTP, CLTC, EPA) with a fully auditable data chain. HBK’s system provides the transparency and accuracy required by certification bodies, ensuring your results are reliable and defensible. 

Vehicle Thermal Management System Testing

Isolate and analyse the energy consumption of HVAC, battery cooling pumps, and other thermal systems. Understand their impact on total vehicle range under different climatic conditions and optimise their control strategies for maximum efficiency.
