Additional Diagnostic Information

🔬 Advanced Diagnostic Tips
  • Battery Chemistry: LFP can charge to 100% regularly, NMC should stop at 80% for daily use
  • Preconditioning: Set destination in nav system for optimal battery temperature
  • Communication Protocols: ISO 15118, CHAdeMO, Tesla protocols have different requirements
  • Thermal Management: Battery heating/cooling systems can reduce available power

🔬 Advanced Diagnostic Tips

  • Thermal Management: Battery heating/cooling systems can reduce available power
  • Grid Constraints: Utility demand charges may cause station power limiting
  • Cable Resistance: Longer/thinner cables can cause voltage drop
  • Communication Protocols: ISO 15118, CHAdeMO, or Tesla protocols may have different handshake requirements
  • Power Electronics: DC-DC converter efficiency varies with temperature and load
