About the role
EV Battery Technician – Battery Diagnostics, BMS, Cell-Level Repair & Battery Health. The technician will be responsible for systematic diagnosis and repair of lithium-ion EV battery packs, including cell-level voltage analysis, internal resistance testing, voltage-sag analysis, temperature monitoring, BMS diagnostics, cell balancing, cell replacement and pack-level inspection. The role requires strong understanding of battery electrical architecture, series/parallel configurations, BMS operation, battery safety and diagnostic measurements. The technician will identify battery failure patterns, determine whether a pack is repairable or economically non-repairable, perform controlled repair activities and document battery health and repair outcomes through EVXpertz diagnostic processes.
