Highly dynamic power supply with excellent current control for testing batteries, and voltage control for testing inverters and electric motors.
AVL E-STORAGE HV
AVL Approach
The AVL E-STORAGE HV is based on an advanced, grid connected, bi-directional DC power supply with an excellent dynamic behavior and enhanced control accuracy that can be easily adapted to meet customer-specific requirements in testbeds and in dedicated laboratories. The system can be operated as a stand-alone DC power supply, battery tester, and battery emulator or can be combined with sophisticated AVL or third party automation systems enabling the testing of e-motors and inverter systems as well as various batteries, fuel cells and super-capacitors. Short rise times and excellent voltage and current measurement accuracies make it ideal for highly dynamic testing while the voltage and current stability, variable output filters and controllable ground fault detection complete the full realm of requirements for advanced testing of batteries and e-drives.
Benefits at a Glance

Problem Solutions
In modern powertrain configurations such as hybrid vehicles, pure electric vehicles or fuel cell powered vehicles, batteries, capacitors, etc. are used for electrochemical energy storage. The energy storage systems have to meet the demand for highly dynamic behavior for both charge and discharge as well as an acceptable lifetime.
Lithium-ion technology offers the highest specific energy, dynamic behavior and efficiency at the moment. The most important parameters for energy storage systems are calendar and cycle lifetime, safety, power, energy and cost. AVL offers accurate, reliable and innovative testing solutions for system validation and development.
