The CAN buses may comprise a drive CAN bus 58, a battery CAN bus 60, and a telematics CAN bus 62. The HV AC compressor 30 may also be connected to the CAN 56 by a further CAN bus 64. The vehicle controller 42 may be connected to the CAN 56 and configured to monitor and/or control the plurality of components of the EV 10 based on CAN signals. Each of the ents can be connected to their tive CAN buses at CAN nodes. Each CAN node may be configured as an input/output device or as an embedded er or controller with a CAN interface and re. Sensors (not shown) may be associated with or embedded in the ents may also be connected to the CAN buses at CAN nodes.
The drive CAN bus 58 may be connected to a motor controller system that ses the motor controller 24 and the electric motor 26. The vehicle controller 42 may be configured to control torque of the electric motor 26 to prevent rollback to y maintain position of the EV 10 when in drive with brake applied. The vehicle ller 42 may be further ured to control regenerative braking by determining if the EV 10 is coasting and adjusting a regeneration current supplied by the electric motor 26 to the HV battery 20 of the EV 10. The vehicle controller 42 may be r configured to measure operating temperature of the motor controller 24 and adjust speeds of the cooling pump 32 and the radiator fan 18 to maintain a predetermined operating temperature. The vehicle controller 42 may be further configured to determine an application rate of an accelerator pedal 44 of the EV 10 and monitor power supplied 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 vehicle controller 42 may be configured to monitor battery ature and optimise current supplied to the HV battery 20 based on the battery temperature. The vehicle controller 42 may be further configured to monitor a state of battery contactors of the HV battery 20 and optimise an amount of time required to start the EV 10. The BMS 22 may comprise the HV power bution box 46 that is configured to selectively activate and deactivate a plurality of auxiliary components of the EV 10 to optimise operating efficiency of the EV 10. The plurality of auxiliary components may comprise the motor controller 24, the HV heater 28, the HV AC compressor 30, the air compressor 36, the power steering pump 38, the HV charger 50, and combinations thereof.

The plurality of parameters may comprise ration, braking, cornering, y regeneration, cabin temperature, speed, d delivery, delivery route, delivery time, diagnostics, repair, maintenance, and combinations thereof. The telematics system may be further configured to communicate the plurality of parameters to a computing device comprising a vehicle entertainment system, a desktop computer, a laptop er, a tablet computer, a smartphone, and combinations thereof.
Referring to Figure 7, the telematics system 48 may be r configured to generate a dashboard (or graphical user interface) 66 on the computing device ying one or more of the ity of operational and/or performance parameters.
The telematics system may implement and embody a "TDDR" principal as follows: • (T)ruck = commercial EV 10 diagnostics and operational optimisation displayed through an online ard. This vehicle stics tool will allow both proactive and ve vehicle monitoring, diagnostics and repair. An example being the proactive reporting of a vehicle LED light failure prior to the EV 10 ing to the depot, so maintenance crews are prepared to repair the vehicle when it returns.
• (D)river = 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 ring driver interaction with the commercial EV 10 (and subsequently having the ability to reward good driver performance), is a key benefit of the telematics system. ional/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 ries and receiver ication. An enormous opportunity to reduce the substantial cost of missed ries for a vast range of reasons. A development intention being to allow the vehicle to proactively communicate intended delivery times to home ries, and allowing the receiver to d (by smartphone response) confirmation of that time, a proposed new time or authorising the driver to leave the consignment in a particular location. The assurance of a delivery providing a dramatic reduction in cost-per-consignment for the operator for an issue that is a proven, g (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 sation. With daily delivery route profiles changing periodically, 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 optimisation can be performed, is critical. An e may be a home ry receiver requesting a changed delivery time in advance, requiring the vehicle to vary its current 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 er of integrated telemetry that offers this full suite of data collection and analysis for commercial EVs. With all four aspects of TDDR analysis 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 ical 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 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.
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; e itself from HV power in case of a fault condition; and adjust fluid in/out temperature based on nmental and user conditions.
