Vehicle Overview

Level-1 Benchmark (

Free

) The FEV Level 1 benchmark provides an initial vehicle overview and comparison of key performance indicators within the FEV scatter bands. We take available data from the vehicle's HMI, OBD and our installed Vbox during road and track testing. Key outputs are initial energy consumption data during WLTC, FTP and RDE cycles and charging performance figures for AC and DC charging. We also provide a nice vehicle overview with pictures, documentation of the HMI screens, information on the powertrain architecture and a subjective driving assessment.

Vehicle Performance Testing

Energy Consumption (

Free

) FEV's benchmarking experts investigate vehicle energy consumption in detail on legislative cycles by installing comprehensive sensor instrumentation and CAN signal reengineering. Key powertrain system components such as the HV battery, EDUs and power electronics, as well as other HV and LV components, are fitted with our sensor instrumentation to capture real data during our test procedures. On our climate-controlled chassis dynamometer, we run legislative cycles such as WLTC, FTP and RDE under different temperature conditions and display energy consumption and recuperation in energy flow diagrams. KPIs are displayed in our FEV scatterplots to compare position with other vehicles on the market.

Control Strategy (

Free

) FEV benchmarking experts capture detailed measurement data during driving cycles and critical mission tests and analyze vehicle control strategies. For example, with our extensive on-board sensor instrumentation, we perform hot and cold start tests, analyze derating behavior during repetitive full load acceleration tests or generate data on regenerative braking performance. The vast amount of measured data is refined and analyzed by our engineering experts and presented in understandable graphs and FEV scatter plots so that our customers can quickly extract the results and key findings from our reports. Raw measurement data can also be provided for further analysis and simulation.

Drivetrain Efficiency (

Free

) During steady-state operation over the speed and torque range at different SOC levels, FEV engineers map drivetrain efficiency numbers. Drivetrain efficiency testing is carried out on a vehicle hub-dynamometer. Overall powertrain efficiency is measured between DC power into the inverter and mechanical power output at the wheel hubs. Optionally, a split into inverter, electric motor and gearbox efficiency can be checked. The feasibility of performing this analysis is highly dependent on the accessibility of installing a 3-phase current measurement between the inverter and the electric motor and must be checked on each specific vehicle.

Charging Performance (

Free

) Equipped with a high-power DC charger in our climatized chassis dynamometer, FEV is able to test charging performance under a range of temperature conditions. During AC and DC charging cycles, we evaluate charge energy/range over time, charge efficiency and usable battery energy. With our own sensor instrumentation, we measure energy losses at various components such as OBC, HV battery and thermal management components. With our charge analyzer equipment and available CAN signals, we can also track the communication between the vehicle and the charging station.

Thermal Management (

Free

) FEV engineers analyze energy consumption and control strategies for thermal management, impacting efficiency, range and comfort. We document thermal loops and operating modes during driving modes and cycles. We also identify all major system components relevant to thermal management. Based on our measurement data during vehicle testing, we analyze heating and cooling strategies, pre-conditioning and show control or target temperatures, e.g. for the EDUs and the HV battery.

NVH Performance (

Free

) FEV NVH experts perform detailed measurements of noise, vibration and harshness (NVH) performance and analyze key characteristics. Using a comprehensive set of instrumentation, including an artificial head, microphones and accelerometers, we measure airborne noise and structure-borne transfer functions. Experienced engineering colleagues perform a subjective assessment against defined NVH criteria. Exterior noise is measured on a certified noise test track in accordance with the official UN-ECE R138e standard.

ADAS/AD Functions (

Free

) FEV's vehicle engineering experts carry out detailed evaluations of Advanced Driver Assistance Systems (ADAS) and Autonomous Driving (AD) functions. All available ADAS/AD functions are documented and control and HMI layouts are explained. Engineering experts perform several driving maneuvers to test the performance of different ADAS/AD functions. Vehicle motion data is captured by installed sensors and cameras. The control strategy and performance during the driving tests are described in our reports.
