Air Conditioning Compressor
The air conditioning compressor is also
driven by an electric motor.
Cab Heater
The cab heater uses energy from the
propulsion battery pack for the cab
heating. It heats up coolant that
circulates through a heater core for the
cab.
Charger
This truck is equipped with a DC fast
charger and has an optional AC charger.
The charger is located on the driver’s
side on the propulsion battery pack.
Chiller
The chiller maintains the maximum
battery operation temperature
threshold by circulating chilled coolant
through the battery packs.
Coolant Pumps
Coolant pumps are used to circulate the
coolant through several coolant loops
on the 520EV.
DC-DC Converter
The DC-DC converter is the battery
electric truck’s equivalent to a diesel
truck’s alternator. The DC-DC converter
uses energy from the propulsion battery
pack to power the low voltage
components such as controllers and
lights and charge the low voltage
battery.
eAxle Differential
Each eAxle has a 3.91 differential ratio
with a 2:1 wheel end ratio, resulting in a
7.82 rear axle ratio.
eAxle Transmission
Each eAxle has a 2-speed or 3-speed
transmission.
Power Steering Pump
The power steering pump is driven by its
own motor.
Powertrain Fan
The powertrain fans are driven by their
own electric motors.
CAUTION!
Use a compatible charger when
charging the propulsion battery pack.
Using chargers that are not listed by
Meritor as compatible may not charge
the truck and negatively affect the
propulsion battery pack life.
