SOC status into the blue 100% full zone. See
Power Indicator Gauge 3 87. When the Charge+
feature is enabled, the battery SOC may still
deplete during aggressive driving.
The Charge+ feature can be used in conjunction
with any drive mode except Weather, Stealth,
or Shuttle mode.
On a racetrack, using the Charge+ feature
optimizes the high voltage battery discharge
rate for sustaining continuous lapping or
to set your fastest lap. When the Charge+
feature is enabled, a strategic discharge rate
is activated, which is the best for continuous
lapping on the racetrack. When the Charge+
feature is off, a maximum discharge rate
occurs, which is best for setting the fastest
lap time. For additional details on vehicle track
preparation, see Chevrolet.com > Corvette
Experience > Guides > Track Prep Guide.
Do not leave the Charge+ feature on longer
than needed since extra fuel may be consumed
due to aggressive charging. Charge+ draws on
engine power to help recharge the battery
quickly, rather than charging efficiently
through brake or coast regen. When the high
voltage battery is full, no additional regen
energy of any type can be captured.
When the Charge+ feature is turned off, the
high voltage propulsion system efficiently
uses battery energy to improve fuel economy
or performance. This allows room in the
high voltage battery for the next regen
charging opportunity. The high voltage battery
automatically seeks its nominal SOC in the
white zone of the Hybrid Battery Gauge,
between 50-80%. The SOC status is displayed in
the HYBRID BATTERY info tile, and is shown in
the blue Hybrid Battery state. See "Info Tiles" in
Instrument Cluster 3 81.
The Charge+ feature is only effective when
the car is being driven. Optimal high voltage
battery charging occurs when the vehicle
speed exceeds 56 km/h (35 mph).
Turning On or Off Charge+
Press the Charge+ button on the driver side
of the center console. When the Charge+
feature is active, the hybrid battery charging
light displays on the DIC. See Hybrid Battery
Charging Light (Charge+) 3 87. Also, a small
pop-up window will also appear showing the
exact SOC and electric power input/output. The
Hybrid Battery Gauge shows the increasing
SOC filling into the blue zone. See Power
Indicator Gauge 3 87.
