Bratitude: created tesla 16v battery page

created tesla 16v battery page

New page

tesla moved from lead acid 12v batteries to a li-ion 16v battery year 2022-current for model 3 and Y. and the model S plaid

* CATL prismatic Cells
* 1p4s
* 99 Wh
* 4 lbs / 1.8 kg
* 16v internally
* LINBUS for vehicle coms on voltage, soh, crash events, etc
* internal BMS: monitors temp, controls charge and discharge rates
* part number 1598486-99-D

its theorized that the CATL cells are the following specs:

* NMC
* 6.9 Ah
* 3.7 V nominal (4.2 V max charge voltage, 2.75 V minimum)
* charging temperatures: from -10°C to +45°C
* discharging temperatures: from -20°C to +60°
* max charging: 10C
* max peak discharging: 50C
* cycle life: >2,000 cycles (80% of initial capacity at 3C rate)

'''The battery locks out in a crash event''', and may even begin bleeding the cells to 0v for safety.

== Charging: ==
if the battery is in a lock out state and will not take a charger, the cover needs to be removed to charge the battery directly.

'''disconnect the cell taps from the bms''', and then connect a 16v power supply to the cell tabs on the bms board. The BMS will need its eeprom/firmware reset

== Cover removal: ==
Removing the cover is required to recharge and re-flash:

remove the 4 bolts that hold cover to the the sealed connector

using a blow torch or heat gun along the edges of lid, this will soften the epoxy sealing the lid in place.

start prying with a flat head screw driver, while applying heat. the lid should release and now be free.

== Software: ==
To reuses the battery, it needs to be reset by dumping the eeprom and re-flashing cleared firmware.

there are a few methods to go about this:

* Xhorse VVDI Prog now supports re-flashing
