Digatron's DCA (Dynamic Charge Acceptance) Tester

All-in-one solution for DCA testing of lead batteries

The exhaust legislation forces car manufacturers to save every gram of CO2 emissions. For small and mid-range cars, the fleet-wide introduction of micro-hybrid concept helps save CO2 without significant investments into expensive technology. The car will save energy through the start-stop function of the combustion engine and brake energy recovery. During recuperation phases, the battery of the vehicle should accept load pulses on concise terms. A measure to evaluate the quality of a battery to allow micro-hybrid load pulses is called “Dynamic Charge Acceptance” or DCA. It is standardized in the European standard EN 50342-6.

Although this procedure has been standardized, it is still very complicated and not easily manageable due to different preconditions like - IF/THEN/ELSE branching and total testing time of 2 weeks. Digatron supports OEMs and battery manufacturers in managing the testing effort and complexity by offering a DCA testing package.

DCA testing is done best with the Digatron UBT-RE tester. It supports a high package density by offering 6 channels per module. Nevertheless, Digatron supports DCA testing also for all former Digatron equipment as well as an add-on to the existing range of equipment.

The DCA package consists of :

  • DCA program for Battery Manager 4(BM4) supporting DCA testing according to EN 50342-6 as well as the Ford run-in test.
  • A key-off resistor assembly to efficiently simulate the load of the board-net during standstill phases.
  • A calculation sheet to calculate the correct resistor value according to the EN standard.
  • Recommended testing hardware - UBT-RE equipment.
If you need assistance or consultation to set-up your battery test bench, our service team is happy to help you.

Save Time & Cost

Save time and buy ready-to-go test from us. Digatron has a team of engineering experts that can do complex programming required for the DCA test in our in-house Battery Manager 4 (BM4) software. The proven programming skills of our experts and weeks of hard work makes this process easier, quick and efficient.


Optimized for UBT & BM4

The package is ready-to-run with the UBT-RE hardware together with our Battery Manager 4(BM4)software platform. The package is compatible with former Digatron hardware too. Moreover, it can also be an add-on to the existing range of Digatron equipment.


Complete Solution Package

Along with the UBT-RE equipment, you will receive not only the DCA software but also the key-off resistor already assembled with a calculation formula to choose the right resistor.


Standardized Solution

The DCA package is developed to closely follow the DCA standard according to EN 50342-6:2015. As an additional benefit, the customers will get the “Ford run-in test” which is published as an appendix of the DCA standard.
