Europe is making significant efforts to ramp up battery production, with maintenance playing a crucial role in enabling this industrialization. To optimize maintenance and effectiveness and efficiency in such complex production, systematic deployment of maintenance performance indicators is essential. We present a case study at a large battery manufacturer in Sweden, involving collaborative research with maintenance development engineers to deploy a set of maintenance performance indicators during battery production ramp-up. The study identifies requirements and provides recommendations for establishing, maintaining, and continuously expanding these indicators in battery production. We contribute to the literature by identifying challenges encountered during this deployment, outlining five requirements; standardization, training, internal integration, management commitment, and data infrastructure, and presenting six recommendations for battery manufacturers to consider; three for establishing the foundations of maintenance performance indicators and three for maintaining this groundwork over time. In effect, these findings address the effective and efficient ramp-up of European battery production.
