Propulsion Motor and Inverter
Each eAxle has one propulsion motor
and inverter. The inverter converts DC
voltage into time-averaged pulses that
approximate the AC voltage needed to
drive the propulsion motors.
Propulsion Battery Packs
There are several high voltage
propulsion battery packs on this truck.
Careful maintenance and operation is
required to maximize the propulsion
battery pack’s life.
WARNING!
The 520EV contains a sealed lithium-ion
high voltage battery. If the battery is
disposed of improperly, there is a risk of
severe burns and electric shock
resulting in serious injury or death.
CAUTION!
Do not store the battery pack in ambient
temperatures above 95 °F (35 °C).
Permanent damage to the propulsion
battery pack will occur.
CAUTION!
To prevent damage to the propulsion
battery pack:

Do not expose the vehicle to
extreme ambient temperatures for
extended periods.

Do not store the vehicle in
temperatures below -13 °F (-25 °C)
for more than seven days.

Do not leave the vehicle for more
than 14 days where the state of
charge gauge (Battery Gauge)
displays a zero or near zero state of
charge.
NOTE
If the outside temperature is -13 °F
(-25 °C) or colder, the propulsion battery
pack may freeze, and it cannot be
charged or provide power to run the
vehicle. Move the vehicle to a warmer
location for the propulsion battery pack
to thaw.
