I don't think it's fair for Tesla to purposely hide the degradation data/make it pretty difficult to get/, especially for not very tech-savvy people. My guess is that there are thousands of units that meet the warranty criteria but the owners would never know, all they see on the app is 100% charged, but is it 100% out of ~13 kWh, or more like 100% out of ~7 kWh? If all this is too technical, I'd encourage the powerwall owners to raise a support case with Tesla and ask for their nominal_full_pack_energy metric. How to find out the degradation of your tesla powerwall battery via pypowerwall tool https://github.com/jasonacox/pypowerwall Tesla Powerwall 2 Battery Degradation Health and Warranty Replacement. Apparently one can use the app "Netzero for Tesla App", I haven't tried it, also I'd be concerned with privacy/security, I think it needs your tesla account credentials to login. The warranty for AU/NZ regions is "70% at 10 years" https://www.tesla.com/sites/default/f... pypowerwall setup commands mentioned in the video ======================== python3 -m venv myenv1 source myenv1/bin/activate pip install -r requirements.txt pip install urllib3==1.26.15 (only if you're getting an error for urllib3) The stat you want to print is print("System Status: %s" % pw.system_status()) ======================== Calculate the percentage of remaining capacity ======================= 100 * (1 - (advertised_capacity_energy - nominal_full_pack_energy) / advertised_capacity_energy) My example: 100 * (1 - (14000 - 9469) / 14000) = 67.6% remaining capacity after 5 years since the install ======================= My stats for comparison ================== nominal_full_pack_energy: 9469 - Value when I raised tesla support case, Regardless how you calculate 14000 or 13500, 9469 it's below 70% of full capacity nominal_full_pack_energy: 15141 - Value of a freshly replaced powerwall nominal_full_pack_energy: 14671 - Value after ~1 months after replacing it ================== 🤖 TLDW (Too Long Didn't Watch) - AI Analysis ⭐⭐⭐ EXECUTIVE SUMMARY ⭐⭐⭐ This video provides a technical tutorial for Tesla Powerwall owners on how to check their battery's degradation, a statistic not available in the official Tesla app. The presenter demonstrates how to physically access the Backup Gateway to find the API password and then use an open-source Python script called 'pyPowerwall' to query the Powerwall's local API. The key metric identified is 'nominal_full_pack_energy', which reveals the battery's current total capacity and allows for calculating its health relative to its original state. ⭐⭐⭐ KEY TAKEAWAYS ⭐⭐⭐ 🎯 The Tesla app does not provide any statistics on Powerwall battery degradation; it must be accessed via a local API. 🎯 The API password is not the user's Tesla account password but is physically printed on a sticker inside the Tesla Backup Gateway 2 panel (it's the last 5 characters of the long password). 🎯 You must connect your computer directly to the Powerwall's own Wi-Fi network (SSID starts with 'TEG') to access its local API. 🎯 The open-source Python tool 'pyPowerwall' can be used to easily query the API and retrieve detailed system stats. 🎯 The key metric for battery health is 'nominal_full_pack_energy', which shows the current real-world capacity of the battery in watt-hours. ⭐⭐⭐ ACTIONABLE ADVICE ⭐⭐⭐ 💡 Open your Tesla Backup Gateway 2 panel and take a photo of the sticker to retrieve the serial number and the password required for API access. 💡 Install Python and Git on your computer if you don't already have them. 💡 Use the command line to clone the 'pyPowerwall' GitHub repository, set up a virtual environment, and install the necessary Python packages listed in `requirements.txt`. 💡 Create a new Python script, copy the example code, and edit it to include your 5-character API password and the Powerwall's IP address (likely 192.168.91.1). 💡 Disconnect from your home Wi-Fi, connect directly to the Powerwall's 'TEG' Wi-Fi network, and then run your script to fetch the battery health data.
