Hybrid vehicle testing

Dewesoft offers a one-stop solution for hybrid engine testing. Our Combustion Analyzer module allows a detailed analysis of the combustion engine while the power analysis module allows perfect analysis of the electric motor, inverter, and batteries. While there are separate solutions for combustion and power analysis on the market, Dewesoft offers a unique solution to measure and analyze both with a single instrument fully synchronized. This gives you the flexibility to test and analyze the entire vehicle with a single DAQ system.

The combustion analysis module can display and compare measurement data using several different diagrams like the pV-diagram (pressure over angle) or the CA-Scope (pressure over angle). All the specific calculations like the mean effective pressure (IMEP, PMEP), heat release, start/ end of combustion (SOC, EOC), start/end of injection (SOI, EOI), indicated power, the maximum pressure (Pmax), derivate pressure (dp/da) are presented either as color diagrams or as a data tables. For more detailed analysis, statistical calculations per cylinder or over the complete engine can be performed.

Additionally, we provide a dedicated knocking detection and combustion noise algorithm. The basis for all of these calculations is precise angle position data and cylinder pressure measurement. Dewesoft provides the perfect hardware for this task. The galvanically isolated SIRIUS DAQ systems charge inputs (with up to 24-bit resolution and 160 dB dynamic range) which are in perfect sync with the Dewesoft Supercounter inputs. This solution offers a perfect analysis of hybrid cars on the road or on the testbed.

The combustion analyzer system can either be used in-car (via the INCA interface) or it can be fully integrated into a test-bed environment. Additional synchronized acquisition from other data sources like video, GPS, CAN, FlexRay, XCP/CCP, and Ethernet, can easily be combined.

Dewesoft offers a unique solution for hybrid powertrain testing by combining combustion and electrical power analysis in a single system. In addition to combustion measurement, the same system enables high-voltage and current signal measurements, making it ideal for testing hybrid engines and powertrains. The combustion analyzer can be used across all types of internal combustion engine vehicles, including passenger cars, trucks, ships, motorcycles, and even power saws.

Hydrogen vehicle testing

Hydrogen vehicle testing requires precise power and efficiency measurements across multiple energy sources, including fuel cells, supercapacitors, and battery packs.

Dewesoft DAQ systems provide a comprehensive solution for measuring AC and DC power, high-voltage and high-current signals (up to 2000A), and hydrogen flow—all in synchronized, high-resolution data acquisition.

EV charging analysis

Charging analysis can be done for conductive charging (AC or DC) and as well for the increasingly popular inductive charging. The inductive charging process (also called wireless power transfer) affords high switching frequencies of the inverter (up to 150 kHz) to reach the maximal efficiency of the power transfer.

The high sampling rate (1 MS/s) and the possibility to measure AC and DC currents of the Dewesoft Power Analyzer fulfill all requirements for testing both, conductive and inductive charging.

Testbed and on-road testing

The innovative solution of DEWESoft® allows measuring the energy consumption of electric vehicles on the test bench as well as inside the vehicle under real-driving conditions with the same measurement device.

Road testing and in-vehicle use

For the mobile application, the data acquisition devices can be powered directly from vehicle power supply or integrated hot-swappable battery packs. All sensors (current transducers, GPS, Video) and further equipment like displays can be powered from the measurement device itself. Also, the zero-flux transducer which need a lot of power (up to 20 watts per unit) can be powered via the additional MCTS power slice.

Testbench testing

The testbench applications require several interfaces on the DAQ side. Protocol such as CAN, XCP, OPC UA, EtherCAT, are required to get data from and to the testbench control system. The Dewesoft data acquisition systems are equipped with all these interfaces so that integration into the test bench environment is very smooth.

Synchronized measurement and analysis of several vehicle parameters

The Dewesoft Power Analyzer offers a wide range of input amplifiers allowing for multi-domain and multi-physics measurements. With combination of our flexible software it is possible to acquire a lot of different parameters, fully syncronized:

Combustion pressure
Torque
Speed
Vibration (IEPE, MEMS, charge)
Strain and force (full/half/quarter bridge)
Temperature (thermocouples, RTDs)
Flow rate
Video (standard, high-speed, thermal)
GPS data (position, acceleration, speed)
Vehicle bus data (e.g. CAN, OBDII, XCP, FlexRay)
etc.

All these additional data sources are synchronized to the power analysis signals, even when they use different sampling rates. This unique combination of time-, angle- and frequency-domain data acquisition in one system makes it possible to run multiple analysis functions concurrently: e.g. electrical power, combustion analysis, order tracking, torsional vibration, and many others.

Exemplary E-Mobility

Standardized driving cycles (NEFZ, WMTC, etc.) are not suitable to measure the energy consumption of electric vehicles. They don’t consider all aspects which influence the energy consumption of vehicles and are always done on roller test benches.

The future of electric vehicle testing is analyzing them under real-life conditions. The innovative solution from Dewesoft allows doing all analysis already during the measurement. The sophisticated math functions can calculate different parameters like efficiency, recuperation, etc. User-friendly and completely customizable software interface allows real-time visualization of all these parameters. The chart shows the exemplary energy flow of an electric vehicle.

Some inverters of electric vehicles (e.g. buses) are working at different switching frequencies to increase the efficiency in different driving situations (city/overland drive). With the Dewesoft math library, it is possible to filter out the currently used switching frequency and automatically do the analysis for different switching frequencies (using logical conditions).

Analyzing and segmenting different driving situations

There are a lot of parameters that can influence the energy consumption of electric vehicles. These parameters can be:

Ambient parameters like temperature, weather, quality of the road
Different driving situations like uphill, downhill, city, overland, or combined drives
Different drivers with different driving habits.

The Dewesoft Power Analyzer makes it possible to do energy analysis considering all of these parameters already during the test drives.

The first chart shows an example of the acceleration behavior of different test drivers on the same test track (left) and the analysis in different driving situations. The acceleration behavior can influence energy consumption by up to 10 %.

The second chart shows the acceleration of the scooter in different driving situations. The green chart is the acceleration with a full-charged battery, the blue one when the battery was nearly empty, the red one for uphill, and the magenta one for downhill driving.

Charging profile, time, and efficiency

The data logging capability of the Dewesoft Power Analyzer allows recording the complete charging process.

Example photo on the right show analyzing the charging profile (red = charging power, orange = energy, violet = power factor):

Charging part 1: continuous charging with high power. Within 4 hours 80% of the battery is charged.
Charging part 2: reaching the charging end voltage and short interruption, 86% charged.
Charging part 3: the last charging part with low power. Within 14 hours battery is fully charged.

EMC testing

Dewesoft supports EMC conformity tests of charging devices according to IEC 61000-3-2 and IEC 61851 standards. The Dewesoft Power Quality module automatically calculates all necessary parameters.

Instruments like the Harmonic FFT, the Harmonic table, Harmonic reference curve, and the scope function ensure fast and reliable analysis.

Harmonic order	Frequency [Hz]	Current [Hz]	Current limit [Hz]
1	50	1,82	-
3	150	1,42	2,3
5	250	0,95	1,14
7	350	0,58	0,77
9	450	0,45	0,4
11	550	0,44	0,33
13	650	0,36	0,21
