I've read that the Taycan modules are electrically similar enough to the older Tesla Model S modules that they can use the same BMS.
EV battery modules mostly come in odd voltage combinations that aren't usually supported by home power equipment. Unfortunately you will also need an inverter whose low-voltage shutdown can be set to about 39 volts, to suit 2 of these modules in series. Most 48v inverters were intended to run on 16S LiFePO4 batteries, so their low-voltage shutdown is around 42 volts.
There are large and expensive BMSes intended for DIY electric vehicles running at 200 volts or more (Dilithium being the most popular). And there's the EMUS BMS, intended to work directly on a single Model S pack. You might ask EMUS if their BMS will work on a Taycan pack--I think chances are good.
Emus BMS Cell Modules are the single cell controllers that measure cell voltage and provide means of controlled dissipative balancing. Each Cell Module can also measure its own temperature and, and is equipped with a special serial interface for communication with the main controller.The 3A...
