Hybrid and Electric Vehicle Test Systems

SAKOR Technologies hybrid and electric vehicle testing systems combine 20-plus years of expertise in engine, drivetrain, and electric motor testing with our considerable knowledge of modern high voltage battery systems. This gives you the confidence that the SAKOR system you select will meet your needs now and into the future.
SAKOR offers a single test system designed for testing a complete hybrid or electric vehicle driveline, or any vehicle sub-system, up to and including complete emissions testing. SAKOR’s Hybrid and Electric Vehicle Test System, winner of the SAE 2008 Technical Award for Hybrid System Technology, has a modular system architecture that includes modules for research and development, performance evaluation and durability testing of:
Electric motor and inverter performance
High voltage batteries and battery management systems
Transmission and mechanical components
Complete powertrain and emissions testing
The Hybrid Vehicle Powertrain Dynamometer Test System uses regenerative technology, resulting in minimal electricity usage and an extremely environmentally friendly “green” profile. Inexpensive to run, the system can save customers thousands of dollars in yearly operating costs. In addition, the system is easily adaptable to any future regulatory testing requirements.
The Hybrid Vehicle Powertrain Dynamometer Test System comes equipped with a specially configured version of SAKOR’s DynoLAB™ EM modular data acquisition and control system optimized for testing hybrid drivetrains. The system:
Can run a wide variety of road load profiles and simulations
Uses industry standard, readily available hardware components
Is completely user-configurable
Is designed for testing to all international standards, including existing and proposed IEEE, EPA, CARB, and Euro standards
Educational Version of the Hybrid Power Test System™ Now Available
SAKOR recently introduced a specially designed educational version of its Hybrid and Electric Vehicle Test System, which sits on a laboratory bench or table.
Gives students a complete understanding of the operations of all components of an electric or hybrid vehicle at a greatly reduced cost.
Comes in 10 to 20 kilowatt versions.
Does limited testing and experimentation on high voltage battery technology. Optional battery simulator facilitates more expanded battery technology testing.
Hybrid & Electric Vehicle Dynamometer Testing
SAKOR Technologies Hybrid Vehicle Powertrain Dynamometer Test System, winner of the SAE 2008 Technical Award for Hybrid Vehicle Testing Technology, is a comprehensive solution for performance, efficiency, and durability testing of all types of hybrid and electric vehicle drivetrains, including:
Hybrid assist (parallel hybrid)
Gasoline or diesel/electric (serial hybrid)
Fully electric vehicles
Combining SAKOR Technologies, core capabilities in combustion engine, driveline and electric motor testing, the Hybrid Vehicle Powertrain Dynamometer System integrates into one unit a Hybrid Vehicle Battery Simulator, one or more AccuDyne™ AC motoring dynamometers, and a DynoLAB™ EM - Sakor Technologies modular data acquisition and control system designed for electric motor testing.
The system is itself extremely power efficient since the unit’s AccuDyne AC dynamometer and Hybrid Vehicle Battery Simulator recapture a large percentage of power used, greatly reducing overall power consumption. This can save customers thousands of dollars in operations costs per year.
Modular and Fully Configurable to Specific Customer Requirements
The Hybrid Vehicle Powertrain Dynamometer Test System can be configured to test all aspects of hybrid drivetrain systems, including engine, mechanical and electric component performance. Components can be tested individually or as fully integrated systems. Examples include:
Engine testing
Generator testing and alternator testing
Battery charge/discharge testing
Electric motor testing
Transmission testing
Entire vehicle drivetrain testing
SAKOR Technologies properly sizes systems for a customer's particular testing needs - we never try to sell more than is required.
Communicates with Intelligent Controllers
The Hybrid Vehicle Powertrain Dynamometer Test System can control the entire testing process by communicating directly with integrated controllers via CAN bus or other vehicle network. Examples include:
Engine control unit (ECU)
Transmission controllers
Battery charging systems
Bus charging units and inverters
Equipped with Top Notch Data Acquisition and Control Software
The Hybrid Vehicle Powertrain Dynamometer Test System is powered by DynoLAB™ EM, Sakor Technologies modular data acquisition and test cell control system optimized for electric powertrain testing. DynoLAB EM:
Can run a wide variety of road load testing and simulations
Uses industry standard, readily available hardware components
Is completely user-configurable
Is designed for testing to all international standards, including existing and proposed IEEE, EPA, CARB, and Euro standards
Educational Version of Hybrid Power Test System Now Available
SAKOR Technologies recently introduced a specially designed educational version of its Hybrid Vehicle Powertrain Dynamometer Test System for use in a small laboratory environment. This tabletop version:
Gives students a complete understanding of the operations of all components of an electric or hybrid vehicle at a greatly reduced cost.
Comes in 10 to 20 kW versions.
Does limited testing and experimentation on high voltage battery technology. Optional battery simulator facilitates more expanded battery technology testing.
Hybrid Vehicle Battery Simulator and Test System
Winner of the SAE 2008 Technical Award for Hybrid Vehicle Testing Technology, SAKOR Technologies Hybrid Vehicle Battery Simulator and Test System is designed for simulating high-voltage batteries in an electric drivetrain testing environment as well as directly testing high-voltage batteries and charging systems.
SAKOR Technologies Hybrid Vehicle Battery Simulator and Test System goes well beyond typical high-voltage power sources previously available for electric vehicle (EV) and hybrid/electric vehicle (HEV) testing. Our customers have told us that when performing EV and HEV drivetrain testing, it is critical to use a power source that will accurately and repeatedly simulate how a particular battery technology will perform in-vehicle regardless of charge state. Our Hybrid Vehicle Battery Simulator does all that and more, allowing them to gather consistent, repeatable, and accurate test data, something that is difficult or impossible to do with an actual battery in the circuit.
When testing of the actual high-voltage battery is required, the Hybrid Vehicle Battery Simulator and Test System, coupled with our DynoLAB EM Test Cell Supervisory System, accurately subjects the battery to the same charge/discharge profile that it would encounter in an actual vehicle, on any desired road course. And it does so with no rotating parts – nothing moves except electrons!
Standard Electrical Capabilities
Continuous power to 1,500 kW
Voltage ranges to more than 900 VDC (volts direct current)
Continuous current in excess of 2,800 amps DC
Transient overloads up to 200 percent for up to one minute
Safety Features
The integral safety features of the Hybrid Vehicle Battery Simulator and Test System continuously monitor the high-voltage system and automatically disable power in the event of most common electrical faults, including:
Isolation/ground fault
Short to ground
Reverse polarity
Voltage balance circuit eliminates inrush surges and component damage due to voltage mismatch
Turn-key Test System Capabilities
The combination of a Hybrid Vehicle Battery Simulator and Test System with our DynoLAB EM Test Cell Supervisory System constitutes a full, turn-key battery test system. Addition of one or more of our AccuDyne AC Dynamometers creates a complete, turn-key EV or HEV drivetrain test system. Since the DynoLAB EM is fully user configurable, the resulting system can perform all types of engineering, production, and quality control testing, including:
Performance testing
Long-term durability testing, including 24/7 unattended operation
Complex vehicle simulation
Dynamic performance modeling
Road load profiles
All EPA, CARB, Euro, and similar drive cycles
Verification of IEEE, CSA, IEC, and NEMA motor efficiency standards
