Modes of Operation

As an example The Plug-In Solutions PHEV conversion has three modes of operation:
1. Standard Mode
2. Enhanced Hybrid Mode (Enhanced mode)
3. Electric Vehicle Mode (EV mode)

Please see company websites for information specific to each manufacturer.

1. Standard Mode

Standard Mode means the car functions the same as an un-modified Prius car. The Owner's Manual describes how to operate the car in Standard Mode.

2. Enhanced Hybrid Mode (Enhanced Mode)

Enhanced Hybrid Mode (Enhanced Mode) is what we call the mode that can deliver over 100 miles per gallon (MPG).

Enhanced mode uses the Toyota Electric Vehicle mode (TEV mode) found on Prius cars sold outside of North America and enhances it by adding an auxiliary battery pack and additional software. Our Enhanced mode minimizes the use of the gas engine and maximizes the use of the electric drive.

You may also hear this mode called "Blended Mode" or "Try EV Mode." In this mode the gas engine continues to operate from time to time whenever the car's computer determines it is needed.

Cars that come from Toyota equipped with the TEV mode have an on-off push button switch to the left of the steering wheel labeled "EV."

Other companies also sell products to provide TEV mode. Our TEV mode will continue to work if a second manual TEV switch is installed in the car.

TEV mode is meant to be used when stuck in traffic jams and other situations where slow, start and stop progress is desired without the gas engine running. This reduces pollution emissions.

Our Enhanced mode improves on TEV mode by providing more power for the electric drive.

Multi-Function Display and Battery State of Charge

The multi-function display (MFD) provides an indication of how much electricity remains in your battery pack, when set to the Energy Monitor Screen. The amount of electricity in the pack is called State Of Charge (SOC). The MFD is the Screen in the center of your dashboard.

Normally the MFD will show the battery SOC fluctuating between green bars (full) and blue bars (half full). This fluctuation reflects the auxiliary battery pack charging up the Toyota NiMH battery pack.

You will know the auxiliary pack is running out of electricity when the MFD stops showing green bars and the number of blue bars slowly decreases.

With a gas powered car you re-fill your gas tank before you run out of gas. The same concept applies to an electric car. You should not run the battery pack all the way down to zero. Stop using the PHEV system when you are on the last blue bar. Switch the PHEV power switch off then charge the battery pack as soon as possible. This will help the battery pack last a long time.

In Enhanced mode the PHEV system will stop discharging when the SOC reaches 40%. The system will still absorb regenerative power after it has reached this point. In EV mode it is possible to drive the car until the pack is completely exhausted. Do not do this.

Driving Tips

1. Use your charge when it best suits your drive.
You can use your electricity when you want to by turning the PHEV power switch on and off as needed. For example, you can save the charge for city streets to minimize pollution in densely populated areas.

2. Go slow.
Driving slow uses less power than driving fast. You will go further on a charge when driving slow.

3. Coasting.
Ride the brake slightly when coasting to produce more regen electricity.

Charging

To charge the car, use a 3 wire, 14 gauge or heavier extension cord, up to 50 feet (15 meters) long. A 3 wired, 12 gauge extension cord is better than 14 gauge for long lengths. Never use a 16 gauge extension cord to charge the car.

Don't coil the extension cord when charging. It will over heat and the plastic jacket will melt.

Use an in-line GFI circuit breaker with the extension cord. Put the GFI at the end that plugs into the house.

Keep the PHEV power switch on (red LED lighted) when charging.

Do not charge the car with the windows closed when it is parked in the sun. Move it into the shade or roll down the windows slightly. The battery charger may over-heat and turn off.

Keep the area around the charger clear when it is charging. It gives off heat and needs to cool itself. If it gets too hot it will shut-off.

The PHEV system will sound a warning buzzer if you start the car when it is plugged into house power. To stop this buzzer, unplug the extension cord at the car.

Do recharge the pack every time the PHEV system is used, so it is ready to go next time.

Charger Operation

We supply three different brands of charger with your system. They are all automatic. No adjustments are needed.

One brand of charger displays output voltage and output current. Typically 4A max and 288VDC.

The car is fully charged when the charger display indicates .25 amps or less.

Normal charge time is 6 hours or less.
