activate and deactivate a plurality of auxiliary components of the EV to optimise
efficiency of the EV.
The plurality of auxiliary components may comprise the motor controller, a HV
heater in a cabin of the EV, a HV air conditioning (AC) compressor, an air compressor, a
power steering pump, a HV charger, and combinations thereof.
The telematics system may be configured to collect and analyse a plurality of

optimise activation of heater elements based on environmental and user
conditions;
isolate itself from HV power in case of a fault condition; and
adjust fluid in/out temperature based on environmental and user conditions.
The HV AC compressor may be configured to:
optimise activation of heater elements based on environmental and user
ions;
isolate itself from HV power in case of a fault condition; and
adjust fluid in/out temperature based on environmental and user conditions.
The cooling pump may be configured to have a variable speed based on inputs
from low-voltage (LV) controls to optimise efficiency of the EV.
The cooling pump may be further configured to have a variable speed based on
inputs from the LV controls to optimise efficiency of the EV.
The battery system may further se a HV r, and wherein the vehicle
controller is configured to evaluate operating ions of the EV through the CAN and

may be configured to control torque of the electric motor 26 to t rollback to
thereby maintain position of the EV 10 when in drive with brake applied. The vehicle

by the motor controller 24 to optimise and report on driving efficiency of a driver of the
EV 10.
The battery CAN bus 60 may be connected to a battery system that comprises
the BMS 22 and the HV battery 20. The e controller 42 may be configured to
monitor battery temperature and optimise current supplied to the HV battery 20 based
on the battery temperature. The vehicle controller 42 may be further configured to

Referring to Figure 7, the telematics system 48 may be further configured to te a
dashboard (or graphical user interface) 66 on the computing device displaying one or
more of the plurality of ional and/or performance parameters.
The telematics system may implement and embody a "TDDR" principal as
follows:
• (T)ruck = commercial EV 10 stics and operational optimisation
displayed through an online dashboard. This e diagnostics tool will
allow both proactive and reactive vehicle monitoring, diagnostics and
repair. An example being the ive reporting of a vehicle LED light
failure prior to the EV 10 returning to the depot, so maintenance crews are
prepared to repair the vehicle when it returns.
• er = telemetry to optimise driver interaction with the commercial EV
, and subsequently optimise vehicle performance. It has been proven in
global studies that a driver can have up to 15% impact on the overall
performance of an EV, hence monitoring driver interaction with the
commercial EV 10 (and subsequently having the y to reward good
driver performance), is a key benefit of the telematics system.
Operational/performance parameters that may be monitored include
acceleration, braking, cornering, battery regeneration, cab temperatures
and speed.
• (D)elivery = ability to interface the "Smart Truck" with payload deliveries
and receiver communication. An enormous opportunity to reduce the
substantial cost of missed deliveries for a vast range of reasons. A
development intention being to allow the vehicle to proactively
communicate intended delivery times to home deliveries, and allowing the
receiver to respond (by smartphone response) confirmation of that time, a
ed new time or authorising the driver to leave the consignment in a
particular on. The assurance of a ry providing a dramatic
ion in er-consignment for the operator for an issue that is a
, growing (due to increased online shopping activity) and expensive
issue in Australia and other widely phically-dispersed markets.
• (R)oute = relates to the importance of route data collection for route
planning and real-time optimisation. With daily delivery route profiles
changing ically, route planning is a critical function of optimised
service delivery. Data collection is key to this function, so ensuring that the
telematics system of the management system 54 can continuously collect
route data, so that both periodical and real-time route sation can be
performed, is critical. An example may be a home delivery receiver
requesting a changed delivery time in advance, requiring the vehicle to
vary its t scheduled route to a more efficient route allowing all
required deliveries and collections still to be made that particular day.
Currently, there is no global provider of integrated telemetry that offers this full
suite of data collection and analysis for commercial EVs. With all four aspects of TDDR
is optimised, a benchmark level of operational and service performance may be
provided. Real time (in-vehicle) software updates, ensure each vehicle utilising the
telematics functionality of the management system 54 has the most recent software and
is continuously diagnosing improvements.
Figures 8 to 15 illustrate components of the electrical system of the EV 10 and
their integration in the management system 54. Referring to Figure 8, the HV heater 28
may be configured to: optimise activation of heater elements based on nmental
and user conditions; isolate itself from HV power in case of a fault condition; and adjust
fluid in/out temperature based on environmental and user conditions.
Similarly, as illustrated in Figure 9, the HV AC compressor 36 may be configured
to: optimise activation of heater elements based on environmental and user conditions;
isolate itself from HV power in case of a fault condition; and adjust fluid in/out
temperature based on environmental and user conditions.
ing to s 10, the cooling pump 32 may be configured to have a
variable speed based on inputs from LV ls to se ency of the EV 10.
The cooling pump 32 may be r configured to have a variable speed based on
inputs from the LV controls to optimise efficiency of the EV 10.

configuration provided by the cooling loop provides optimised series/parallel cooling
system for e level electrical components, including the motor controller 24, electric
motor 26 and HV charger 50.
Figures 12 and 13 respectively illustrate example functional implementations of
the cooling fan 18 and the DC/DC inverter 34 in the EV 10.
Referring to Figures 14 and 15, the vehicle controller 42 may be configured to
evaluate operating conditions of the EV 10 through the CAN 56 and control the control
the HV charger 50 to optimise power supplied by HV direct current (DC) to charge the
HV y 20.
