Mobile Diagnostics, 48V Battery Repair, DC‑DC Converter Faults & Mild‑Hybrid System Support Across London

Modern vehicles increasingly use 48‑volt mild‑hybrid systems to improve efficiency, torque delivery, emissions and start‑stop smoothness. These systems combine:

  • 48V motor‑generator
  • 48V lithium battery pack
  • 48V DC‑DC converter
  • Hybrid control module
  • Regenerative braking
  • Torque‑assist and start‑assist functions

When a fault occurs, the vehicle may lose torque support, disable start‑stop, show hybrid warnings, or enter reduced‑power mode.

FixAnyEV provides full mobile diagnostics and repair for all 48‑volt mild‑hybrid systems across London.
