EVTV has worked with Speedhut to develop a custom gage set for use in our Tesla Drive Unit that displays vehicle data received on the Controller Area Network or CAN bus.
This gage set uses standard J1979 CAN Parameter Identifiers or PIDS for speed, rpm, engine coolant temperature, fuel level and auxiliary voltage. But we have modified these gages to show Electric Vehicle State of Charge (SOC) on the fuel level indicator, inverter temperature on the engine coolant gage, and pack voltage on the aux 12v gage. The gages have been custom printed to show these values and we have scaled those values as appropriate. Additionally, we use the Tachometer for both RPM and AMPS as desired.
These gages can easily be adapted to any CAN based control system on any electric vehicle.
The PowerKey Pro was built with two things in mind, make it tough and make it flexible. So we made the PowerKey Pro reprogrammable, relegendable and open. That’s right, open. The PowerKey Pro is an open protocol CAN-BUS keypad the CANopen protocol.
CANCrocodile does no damage to insulation of wires and has no direct electrical contact with CANbus. Data reading occurc in a contactless way – CANCrocodile detects magnetic field around CAN-High and CAN-Low wires.
The design of the body provides perpendicular fixing of the wires to reading surface. This way of fixing will not allow the CAN bus wires to slip from the CANCrocodile reading surface.
A soft pressure pad in the upper part of the housing tightly presses the wires to reading surface.
Red indicator – power is on, blinking green indicator – messages receipt from CAN bus. Indicaters allow to test the operability of the reader without dismantling and connecting to monitoring terminal.
