The AVL E-STORAGE LV Tester is optimized for testing of low-voltage micro and mild hybrids. The integrated safety relay (ISR) interrupts the flow of energy between the mains connection and the DC connection in the power supply completely in the case of an emergency stop and can be integrated into an additional safety circuit. Additionally adjustable monitoring limits are linked with the safety system of the E-STORAGE LV. Equipped with the advanced AVL Battery Models, the E-STORAGE LV can accurately emulate a real battery supplying the device under test with a voltage that depends on multiple input parameters. The E-STORAGE LV is fully compatible with AVL’s engine and vehicle test systems allowing an easy integration into existing testbeds, but can be also operated as a stand-alone application. Excellent EMC characteristics with lower noise levels enable applying sensitive measurement sensors in close proximity. Thanks to a protection class up to IP54 the system can be placed in a test cell without additional F O C U S 2 9 protection. < existing battery system should be available in a reproducible way the new product can be used for emulation purposes and therefore supports vehicle development, in particular the commissioning phase. The commissioning time now can be significantly reduced since the battery in many cases is the most critical component in terms of timing (availability). The AVL E-STORAGE LV Tester is an indispensable product for the development of future sustainable 48 V powertrains and optimized for testing of low-voltage micro and mild hybrids. The E-STORAGE LV is a low- voltage variant from the successful E-STORAGE product family that is optimized for the characterization and verification of electric driveline components in the automotive, marine, aviation and stationary power industry. The system is based on an advanced grid connected regenerative DC power supply that can be easily adapted to meet customer-specific requirements in testbeds and in dedicated laboratories. Thanks to its excellent dynamic performance and high control accuracy > the device can precisely follow a predefined duty cycle to expose the device under test to a real operating condition e.g. a cold-start of an engine. A wide voltage range, low ripple level and excellent EMC characteristics allow operating and testing of different units under test in highly sensitive environments. The Basic Safety Concept facilitates the integration with the interlock circuit of the testbed.
