Sakor Technologies, Okemos, Mich., recently introduced its Hybrid Vehicle Battery Test System, a complete offering for high-voltage battery testing. The system is extremely energy efficient and can perform all types of performance and durability cycling, including complex profiles and road load simulations.
Driven by a DynoLAB EM controller, the Hybrid Vehicle Battery Test System inherits DynoLAB's ability to automate all types of performance, durability and continuous cycling operations, including full road load simulation. Not only does the system function as a battery tester, but also as a battery simulator. Integration with a HybriDyne Hybrid Driveline Dynamometer creates a system capable of testing complete hybrid drivelines and subsystems with or without actual batteries in circuit. The system may be configured to provide dynamic response (i.e., voltage sags and current surges) just as would be seen in-vehicle. Unlike the performance of an actual battery, the simulator output remains repeatable from cycle to cycle, regardless of charge status, resulting in more consistent and accurate test data.
The Hybrid Battery Test System is available with voltages of up to 1,000 Vdc. Typical systems range from ±200 A to ±2,400 A (continuous), and most units offer overload (surge) currents of up to 200% of the rated current.
