Tesla Model S Battery Module Controller Basics Kit
Previous1 of 15Next
 The Tesla Model S Battery Module features it's own proprietary Battery Management System board that reports the voltage of each cell in the module, temperature of each module terminal, and can actively balance each cell in the module.  But it uses a very proprietary serial communications scheme to report this to the main BMS board in the Tesla Battery Pack.

We have reverse engineered this scheme and developed a specifically designed shield to communicate with it, along with a series of cable harnesses to connect to the batrtery modules.  

This shield mounts on our EVTVDue microcontroller to provide an embedded system to control and monitor up to 62 individual battery modules.

Beyond voltage and temperature monitoring and balancing, this controller has the capability to operate two Gigavac contactors to connect your system but more importantly, to DISCONNECT it if any cell goes beyond voltage or temperature limits YOU set.  And it does much more, like control external MPPT charge controllers and heating or cooling.  It also provides CAN ports to communicate with your other equipment or support inverters such as the Sunny Island 6048.

We've gone to some lengths to develop a complete software solution you can configure and observe with a laptop computer and USB connection using simple ASCII text commands. But this solution requires a certain set of other componentts to operate.  This kit contains the minimal system required to satisfy the software.

LifePo4 Replacement for Tesla Model S/X 12v Battery
Previous1 of 5Next
 Drop in LiFePo4 lithium battery drop-in replacement for Tesla Model S/X lead 12v battery.

One of the little ironies of the Tesla Model S and X is that despite having THE most advanced lithium battery chemistry design in the world to drive the car, they then saddle it with a weeny lead acid 12v battery that 
has proven to be THE highest failure rate component in the car.

Under warranty, this is only annoying as they will and do replace these constantly.  But after the warranty expires, you won't want to keep this unlikely situation.  Replace it with a long lasting safe LiFePo4 lithium 
12v battery.
