EV Controls T-1C


the T1-C contains extra hardware to control a variety of outputs that almost all installations and conversions would require.

This unit’s outputs will control;

-Brake lights. Brake light output is activated when the brake pedal is depressed or when regenerative braking exceeds a certain threshold.

-Inverter 12V power. Inverter 12V power should only be applied at the correct point in the power up sequence, after CAN transmission has been initiated.

-Inverter cooling fan control. This output will trigger the inverter cooling fan at a user adjustable inverter coolant temperature, adjusted via the touchscreen.

-High voltage positive contactor.

-High voltage negative contactor.

-High voltage pre-charge relay.   The controller will close the negative contactor, then the precharge relay, then after a set delay, it will close the positive contactor. this is to avoid welded contactors.

-The controller can also be configured to control a charger and DC/DC converter.

The EV Controls T-1C is a full featured controller for the Tesla drive unit.

It can control both the S-85 and P-85 drive units at at this time, support for the smaller “D” drive units is in the works.

This unit communicates with the inverter over the CAN bus, and will allow you to do the following;

-Engage drive, neutral and reverse modes via the 7″ touchscreen,

-Adjust peak power output and regenerative braking power levels via the touchscreen,

-Display the following data on the 7″ touchscreen;

-Drive mode (D, N ,R)

-Traction pack voltage (HV)

-Inverter 12V supply voltage

-Accelerator position

-Stator current

-Actual power in kilowatts, positive or negative (regenerative braking)

-Max power limit

-Max regen power limit

-Five internal inverter temperature readings

-Vehicle speed (user adjustable scaling to account for wheel diameter)

-Current brake pedal and regen state

-Diagnostic data.

The inverter firmware needs to be updated to a version that is compatible with our controller, and we can do this remotely.

This product does not currently include a wiring harness. We suggest you source the inverter wiring harness, accelerator pedal, and brake pedal switch when you purchase the inverter.
