System tests hybrid vehicle batteries

Sakor Technologies, a leader in hybrid vehicle drivetrain testing, has introduced the Hybrid Vehicle Battery Test System for high-voltage battery testing. The energy efficient system can perform all types of performance and durability cycling, including complex profiles and road load simulations.
At the heart of the system lies a high-efficiency, line-regenerative DC power source. During discharge modes, absorbed power is regenerated back to the AC mains instead of being dissipated as wasted heat, which is common practice among other battery testing systems. This innovative method generates greater power efficiency and measurably reduces overall operating costs.
Driven by a DynoLAB EM controller, the Hybrid Vehicle Battery Test System can function both as a battery tester and 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 (ie, 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 1000 V d.c. Typical systems range in size from ±200 A to ±2400 A (continuous), and most units offer overload (surge) currents of up to 200% of the rated current.
