TESLA MODEL 3 BATTERY & MOTOR CONTROLLER

This controller has been specifically designed for the Tesla Model 3/Y rear motor or battery or both and is manufactured with automotive quality parts. It's completely waterproof. It allows the use of any used Model 3/Y motor with any battery between 300-400 volts. The motor and/or battery will have to be reprogrammed at our installation before delivery. If you have your own battery, we will need to reprogram them remotely with the necessary equipment before installing it in the vehicle to be compatible with our controller. If you have your own motor, you will need to send us your inverter so we can program it. 

What you need to know for the battery controller
We can guarantee the operation of our controller only if the battery is intact and has not been removed from its original casing and the precharge works with the same or lower capacitance than the original motors.
-Mode
The battery can be controlled in 3 different ways for the functions: DRIVE-CHARGE-
STANDBY
The first method is by CAN bus messages which will be provided with a CAN database
which also allows to receive states such as : Voltage, number of kWh available, state of
charge, power in kW, in/out current, contactor status, 12V battery voltage, battery insulation, requested flow rate for coolant pump, and more.
The second method is with digital inputs to control: precharge and contact, charge or
discharge mode, with the use of buttons. There are also outputs to authorize discharge and recharge. The battery can be used with the original charging port and its computer to connect a level 1, 2 or 3 charging station.
-Precharge
In the TM3 battery, there is no precharge relay or resistor. The Model 3 uses the 12V battery and the PCS to increase the battery voltage by 12V to match the pack voltage. The PCS becomes a key element in closing the pack's contactors. If there is a short circuit or if the capacitors of the equipment connected to the high voltage line are too large and take too long to charge the precharge will approach and the contactors will not close. It is important to do a precharge test with the battery and your equipment to confirm compatibility.


What you will need with your battery

If you have your own battery of Tesla model 3 you will need to make sure of several things.
First of all if it comes from a crashed vehicle it may very strongly need to replace the Pyro-fuse. You can order it directly from Tesla. Part Number: 1064689-00-I
With your battery you will need the charge port, charge port ECU and high voltage connectors.

Good to know

If you want to control a battery :

The 32A or 48A on-board charger (OBC) is functional and can be adjusted in amperage and percentage of charge.

The DCDC 12 is also functional and can be adjusted from 12-15V.

Several batteries can be connected in parallel for larger projects.

 

How does it work?

The Motor can be controlled in 2 different ways for the functions: DRIVE, REVERSE, PARK, CREEP and REGEN.

Method #1 : The first method is by CAN bus which will be provided with a CAN data base. This data base allows to receive live data like speed, power, regen, voltage, temperatures. It also allows the control of several limitations such as maximum power, regen by braking, traction control and more.

Method #2 : The second method is with digital inputs to control PRND, creep and regen with buttons. There are also outputs to turn on reverse and brake lights.

 

The battery can be controlled in 2 different ways for the functions: precharge/contact charging, drive/discharge.

Method #1 : The first method is by CAN bus which will be provided with a CAN data base. This data base allows to receive live data such as voltage, number of kWh available, percentage of charge, power in kW, current in/out, contactor state, 12V battery voltage, HV battery insulation, coolant flow request and more

Method 2 : The second method is with digital inputs to control precharge and contact, charge or discharge mode with the use of buttons. There are also outputs to authorize discharge and charging.

The battery can be used with the original charge port and its computer for connecting to a level 1 or 2 charging station.

 

Installation
You can buy a complete set which includes the motor and the controller with all the necessary harnesses. Also available as an option: the rear subframe with suspension, axles and battery. If you already have your motor and/or battery and you only want our controller, you will have to buy about 500$ of equipment to reprogram the motor remotely. Be careful because you must have a high level of knowledge in electricity and electronics to be able to do it yourself.
