Battery status

Key indicators

• Pack voltage: 219V → normal for your RX400h
• State of charge: ~51% → right in the typical operating range (these cars hover ~40–60%)
• Volt diff: 0.09V → excellent
  • Anything under ~0.2V is considered well-balanced
• Block voltages (~21.8–21.9V each) → very consistent
• Internal resistance: ~29–31 mΩ → uniform across blocks (good sign)
• Temps: 86–92°F → normal, no overheating

What would worry me (but you DON’T have)

• Large voltage spread (>0.3V)
• One block consistently lower than others
• High or uneven internal resistance
• Rapid SOC swings

What this means

Your battery:

• Is well balanced
• Has no obvious weak module
• Is aging normally (if at all noticeable)
