DC sources / sinks for testing rigs safeguard product quality

Realistic, high-quality tests with different operating states and exacting requirements

DC sources / sinks for testing rigs are a core component in the development, quality assurance and EOL (end-of-line) testing for batteries and power electronics in the domain of e-mobility. The dynamic properties, the combination of high control accuracy, low residual ripple, and a large output voltage range are crucial. This means that, with the DC sources / sinks for testing rigs, users have the ability to efficiently cover high-voltage applications as well as 48-Volt applications with just one testing rig energy system. Various software packages enable the DC sources / sinks for testing rigs to be used as battery simulators or battery testers, allowing the following applications to be supported, for example:

  • Battery simulation
  • Battery testing
  • Inverter and DC engine test for EV & HEV
  • Testing of charging stations
  • DC Sources / Sinks for Testing Rigs
  • Testing of power electronics (DC / DC converters)
  • DC load for fuel cells

Heinzinger DC sources / sinks for testing rigs in the ERS series allow practical and realistic testing with excellent quality. As a key core component of all kinds of testing rigs, in research and development or from quality assurance to end-of-line testing, they offer their users long-term investment security. The return of unused energy into the supply network also ensures that the DC sources / sinks for testing rigs deliver excellent energy efficiency and low operating costs. 

By using a twin-channel device, two items being tested can be supplied with power simultaneously, opening up a variety of different operating options for the DC sources / sinks for testing rigs. This means that, through “energy balancing”, all of the energy can circulate between the test items across both output channels. This produces fewer losses than if individual devices were being used, and only the test item's losses from the grid have to be tracked. As a result, even with lower installed mains power, tests can be carried out with a high power demand. Another advantage of using a twin-channel device is the opportunity to increase power for one output channel. We will be happy to advise you other possible uses for a multi-channel system

DC sources / sinks for testing rigs for battery simulation

The devices in the ERS series are designed especially for battery simulation. The following features of the DC sources / sinks for testing rigs are important:

  • table output voltage even with pulse currents
  • Simulation of the battery’s internal resistance
  • Parameterizable battery models
  • Dynamic rated value change up to 1 kHz
  • Continuous transition between source and sink mode
  • Switchable insulation monitor function

Battery tests and verification of high-voltage batteries

For testing rigs used to test and verify high-voltage batteries from the EV and HEV sector, the DC sources / sinks must meet special requirements. These include, among others, the following criteria:

  • Currentless connection of the battery
  • Charging and discharging mode with automatic switch-off
  • Discharging of the output capacities on switch-off
  • Rated value monitoring and monitoring of the system limits
  • Automatic toggling of control types
  • Switchable insulation monitor function
