Kia EV9 Charging Performance: Real-World Data From 5,000 Miles
Understanding EV9 Charging Fundamentals
The Kia EV9 represents a significant step forward in three-row electric SUVs, but like all EVs, its charging experience depends on multiple factors. Unlike gas vehicles where fill-up time depends primarily on pump speed, electric charging involves a complex interplay between:
Key Charging Variables
Battery capacity: 76.1 kWh (Light trim) or 99.8 kWh (all other trims)
DC fast-charge rate: 235 kW (small battery) or 210 kW (large battery)
AC Level 2 rate: 10.9 kW maximum across all trims
Charger capability: Equipment limitations affect actual speeds
Battery state: Temperature and charge level impact performance

It's important to note that usable battery capacity is slightly less than the total figures Kia publishes - a common practice among automakers to preserve battery longevity.
Level 2 Charging: The Home Charging Experience
After extensive testing with various Level 2 chargers (240V), we've compiled these key findings about home and destination charging:
Average Charging Speed
0.4 miles per minute
Equivalent to adding about 24 miles of range per hour
Typical Session Duration
7 hours 14 minutes
Most often overnight when electricity rates are lowest
Practical Implications
Full recharge from 10% takes approximately:
Small battery: ~9 hours Large battery: ~11.5 hours
These numbers reflect real-world conditions where charging often occurs alongside household electrical loads. For most owners, Level 2 charging provides a "full tank" every morning without requiring dedicated charging stops.

DC Fast Charging: Road Trip Performance
Our testing across multiple DC fast charger networks reveals how the EV9 performs when you need quick power on the go:
Charger Type
Peak Charge Rate
Average Miles/Min
10-80% Charge Time
50 kW
48-50 kW
3.1
~75 min
150 kW
142-150 kW
5.2
~32 min
350 kW
195-210 kW
6.8
~24 min
Tesla Supercharger (250 kW)
88 kW*
2.9
~85 min
*With Magic Dock adapter, your experience may vary
DC Fast Charging Best Practices
Charge to 80%: Speed drops significantly beyond this point
Precondition: Use navigation to chargers for optimal battery temp
Peak rates: Maximum speeds typically occur between 10-50% state of charge
Network matters: Reliability varies significantly between providers

Charging Curve Analysis
The EV9 maintains an impressive charging curve, particularly with the larger battery pack. Our testing shows:
10-50% State of Charge
Peak charging speeds
180-210 kW sustained
Adds ~150 miles in 15 minutes
50-80% State of Charge
Gradual decline
90-140 kW average
Adds ~100 miles in 20 minutes
80-100% State of Charge
Significant slowdown
30-50 kW typical
Adds ~60 miles in 30 minutes
This curve suggests the EV9 is optimized for the 20-80% charging range that represents typical road trip behavior, with dramatically reduced speeds above 80% to protect battery health.
Practical Ownership Implications
Based on our 5,000 miles of experience, here's what prospective EV9 buyers should consider:
Home Charging
Install at least a 48A Level 2 charger for maximum speed
Schedule charging during off-peak hours for cost savings
Daily charging to 80% extends battery life
Road Trips
Plan stops at 150kW+ chargers when possible
Target 10-60% charge sessions for fastest results
Verify charger status via apps before arrival
Cold Weather Considerations
Expect 15-20% range reduction in freezing temps
Charging speeds may decrease without preconditioning
