These are usually temporary in nature, meaning they will disappear either during the drive or at the latest after a restart. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the vast majority of cases, the error occurs when regenerative braking (engine braking\/energy recovery) is used while driving downhill, immediately after starting the descent and with the battery charged to 100%. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since the battery is fully charged, it cannot absorb regenerative energy. The system voltage briefly exceeds the limit, and the system throttles the regenerative braking power for self-protection.<br><br>Erscheint die Warnung bei normaler Fahr, also nicht bergab und mit Rekuperation, kann dies auf ein Problem einer oder mehrere Zellen hinweisen. Im Vergleich zu den restlichen Zellen im Akku weisen diese abweichende Spannungen auf &#8211; man spricht von \u201eCell Drift&#8220;.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Solution<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Test the battery with the <a href=\"https:\/\/wp.stromer-tech.info\/en\/knowledge-base\/battery-self_check-recognize-problems\/\" data-type=\"ht_kb\" data-id=\"676\">Akku _CHECK<\/a>. <br><br>Sind alle Checkpunkte OK und gr\u00fcn ist der Akku zu 99% in Ordnung.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Wenn nicht, kann ein Kontaktproblem zwischen Akku und Akkufachsockel, ein Problem mit dem Wicket Cable oder im schlimmsten Falle eine \u201eCell Drift&#8220; vorliegen. <br><br>Bei Letzterem muss der Akku an Stromer zur \u00dcberpr\u00fcfung eingesendet werden. In den meisten F\u00e4llen liegt ein Akkudefekt vor und der Akku muss ersetzt werden. Eine Alternative ist den Akku mit neuen Zellen zu best\u00fccken. Dies bedingt aber, dass das BMS noch funktioniert, sowie ein Reset des SoH (State of Health) und des Ladezyklenz\u00e4hlers durch den Aufbereiter gemacht werden kann.
