CRUISING RANGE IS SHORT

id300300001100

Outline

Malfunction symptom

Cruising range is short

Description

•  The cruising range has become shorter than previous.

•  The remaining distance-to-full discharge displayed in the instrument cluster fluctuates considerably while the vehicle is being driven.

Possible cause

Note

•  Lithium-ion batteries used as high voltage batteries have the characteristic of gradually decreasing (deteriorating) their capacity as they are used.

•  The deterioration rate can be reduced by paying attention to the following.

When charging:

―  Avoid frequent charging as much as possible

―  Use normal charge instead of quick charge as much as possible

―  Do not always fully charge, only charge required amount

When parked:

―  Do not store vehicle at location where ambient temperature is extremely high or low

―  Do not leave vehicle when high voltage battery level is extremely low

When driving:

―  Avoid driving that uses large amounts of power within short time such as sudden acceleration

Driving that causes poor power consumption rate:

―  Driving vehicle under conditions that have greater impact on power consumption rate than previous (See POOR POWER CONSUMPTION RATE.)

High voltage battery deterioration:

―  Charging capacity decreases due to high voltage battery deterioration

Diagnostic Procedure

Step

Inspection

Results

Action

1

DETERMINE IF MALFUNCTION CAUSE IS HIGH VOLTAGE BATTERY DETERIORATION OR POOR POWER CONSUMPTION RATE

•  Verify the average power consumption rate in the instrument cluster.

•  Is the average power consumption rate (km/kWh) lower than previous?

Yes

Perform troubleshooting according to [POOR POWER CONSUMPTION RATE].

(See POOR POWER CONSUMPTION RATE.)

No

Go to the next step.

2

VERIFY TEMPERATURE WHEN CHARGING

•  Verify with the customer the ambient temperature at the time of charging.

•  Is charging performed during low temperatures (below freezing) often?

Yes

Explain to the customer that charging efficiency decreases when charging during low temperatures.

No

Go to the next step.

3

VERIFY DISCHARGE CONDITION

•  Verify the high voltage battery level in the instrument cluster.

•  Is the high voltage battery level indication (---)?

Yes

Go to Step 5.

No

Go to the next step.

4

DISCHARGE HIGH VOLTAGE BATTERY

•  Start the EV system.

•  Perform the following and discharge the high voltage battery until the high voltage battery level indication is (---).

―  Set air conditioner MAX COLD (windows fully open)

―  Turn on Headlights

―  Operate seat warmer and heated steering wheel

―  Operate rear window defroster

—

Go to the next step.

5

CHARGE HIGH VOLTAGE BATTERY BY NORMAL CHARGE

•  Charge the high voltage battery by normal charge until the high voltage battery level indicator in the instrument cluster reaches 100%.

—

Go to the next step.

6

VERIFY EV SYSTEM RELATED DTCs

•  Perform the DTC inspections for the following modules.
(See DTC INSPECTION.)

―  PCM

―  BECM

―  Battery charge control module

•  Is a DTC displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC TABLE [PCM (e-SKYACTIV)].)

(See DTC TABLE [BECM (e-SKYACTIV)].)

(See DTC TABLE [BATTERY CHARGE CONTROL MODULE (e-SKYACTIV)].)

No

Perform troubleshooting according to [POOR POWER CONSUMPTION RATE].

(See POOR POWER CONSUMPTION RATE.)
