How healthy is the high-voltage battery? Two options for workshops in the future

To be able to assess the SoH beyond manufacturer definitions and thus an objective vehicle evaluation, Hella Gutmann is developing the 'Pro' HV battery diagnostics in cooperation with Battery Quick Check GmbH, a joint venture of TÜV Rheinland and TWAICE Technologies GmbH. Evaluation via proven analysis algorithms provides objective facts about the actual SoH of the high-voltage battery and also allows conclusions to be drawn about previous usage behaviour, an important point, for example, when expert vehicle assessments are carried out for lessors and insurers, because the frequency of rapid or exhaustive discharges blatantly accelerates the ageing process of a lithium-ion battery. In contrast to existing solutions on the market, Hella Gutmann and its partners do not rely on time-consuming battery loads while driving. Instead, software-controlled loads are applied via the mega macs X diagnostic unit and wallbox during the charging process, for example in the workshop. Recorded measured values are immediately evaluated algorithmically. Battery diagnostics from the 'Pro' HV is expected to be feasible within one hour. A final certificate, with the process certified by TÜV Rheinland, documents the condition assessment of the high-voltage battery, independent of the manufacturer, and thus forms the watertight basis for certificates and monetary vehicle valuations.
