Norwegian Connections between the cells
Battery modules contain many cells and electrical connections. Damaged connections, corrosion or other abnormalities can affect performance and need investigation alongside the rest of the battery.
Diagnosis before repair
We use logs and measurements to identify areas requiring closer investigation. Repair options are assessed once condition and the extent of the fault are understood.
