The Power Flow Monitor: Your Hybrid’s Energy Story
The Power Flow Monitor is displayed on both the Driver Information Interface behind the steering wheel and, on equipped trims, the Display Audio screen. This graphic shows a simplified view of your vehicle’s powertrain components and uses animated arrows to show energy flow.
Reading the Colors
Here’s the key to understanding what you’re looking at:
- Blue arrows indicate power being supplied to the wheels
- Green arrows indicate the battery is being charged
When you see blue flowing from the battery to the wheels, you’re driving in EV mode. When you see green flowing from the wheels back to the battery, you’re capturing energy through regenerative braking. When both colors appear, the system is balancing power delivery and charging simultaneously.
The Three Power Modes Explained
The Accord Hybrid automatically selects the most efficient power source based on driving conditions. But when is the car using which mode?
EV Drive Mode
What it is: Your Accord Hybrid is propelled exclusively by the electric motor, using power from the lithium-ion battery pack.
When it happens: Low-speed driving, light acceleration, and short trips around town. The system can operate in EV mode up to approximately 60 mph under ideal conditions.
How to force it: Press the EV button near the shift lever to manually enable EV mode. The EV indicator will appear on the instrument panel.
Important limitations: The system may automatically cancel EV mode and switch to hybrid operation if the battery charge gets low, if you ask for too much power (“Hard Acceleration Requested”), or if road conditions demand more output. One reviewer noted that the Accord Hybrid “will coast in EV mode all day, according to its own whim and depending on your throttle input”.
Hybrid Drive Mode
What it is: The gasoline engine powers a generator, which in turn supplies electricity to the drive motor that propels the wheels.
When it happens: This is the default operating mode for most city driving and moderate acceleration. The engine runs at optimal RPM to generate electricity, while the battery can also contribute power when needed for extra oomph.
Engine Drive Mode
What it is: A clutch engages to mechanically link the gasoline engine directly to the front drive wheels.
When it happens: Highway cruising at steady speeds. This direct mechanical connection is more efficient at high speeds than converting engine power to electricity and back.
Expert Insight:
“When driving, your vehicle is propelled exclusively by the electric motor, exclusively by the gasoline engine, or by a combination of the two. The system selects which propulsion source is most appropriate and automatically switches to it.”
Additional Energy Dashboard Features
Deceleration Paddle Selectors
The Accord Hybrid features paddle shifters on the steering wheel—but they don’t change gears. Instead, they adjust the level of regenerative braking. The Driver Information Interface displays up to four arrows indicating your selected deceleration level.
Higher regeneration levels mean more energy recaptured when you lift off the accelerator, which means more battery charging and less brake pad wear.
Eco Drive Display
The Eco Drive Display provides real-time feedback on how efficiently you’re driving. The system uses a visual “coach” to show your acceleration and deceleration style:
- Smooth, steady acceleration = maximizes fuel efficiency
- Aggressive acceleration = lowers fuel efficiency
- Smooth, steady deceleration = maximizes energy recovery
- Aggressive braking = wastes energy
As you drive efficiently, you earn leaves on the display. When you turn the vehicle off, your drive cycle score and lifetime score are displayed.
Ambient Meter
The ambient meter uses color-coded bars to indicate real-time fuel efficiency—green for efficient, blue for moderate, and a third color for low efficiency. It’s a quick visual check to see how you’re doing without looking away from the road for long.
Where to Find the Displays
Driver Information Interface
Located on the left side of the instrument cluster, the Driver Information Interface provides a versatile readout of numerous important systems. On Accord Hybrid models, it shows:
- Energy-flow graphic showing how the hybrid system is operating
- Deceleration levels with up to four arrows
- Eco Guide to help learn fuel-efficient driving techniques
- Fuel economy, range, and trip information
Press the right selector wheel on the steering wheel to navigate through different displays, including trip meters, average fuel economy, and instant fuel economy.
Display Audio Screen
On equipped trims, an animated power-flow meter appears on the Display Audio screen. This larger display shows the same energy information with more detail and easier-to-see graphics.
Head-Up Display
The Touring trim level adds a Head-Up Display that projects key information—including power/charge meters—onto the windshield.
Practical Tips for Using the Displays
Maximizing EV Mode
The Accord Hybrid’s EV mode is designed for short trips and low-speed driving. To get the most out of it:
- Press the EV button before starting your trip to force electric-only operation
- Watch the Power Flow Monitor to see when the engine would kick in
- Anticipate stops using the deceleration paddles to maximize regenerative braking
- Avoid hard acceleration—the car will remind you with a “Hard Acceleration Requested” message if you overdo it
Understanding Range Estimates
The range display shows the estimated distance you can travel on remaining fuel and battery power. Keep in mind that this is an estimate—actual range may differ based on driving conditions and style.
Reading the Average Fuel Economy
The average fuel economy display is tied to each trip meter. Reset Trip A when you fill up to track your current tank’s efficiency. Trip B can track longer-term averages.
Frequently Asked Questions
