Earlier this week, many Tesla Powerwall 2 users had their systems remotely disabled due to a Product Safety Report. This report was issued by the UK Government as it was found that some units may present a risk of fire due to certain battery cells inside affected units developing internal defects over time.
What has happened?
The Tesla Powerwall 2 has been under investigation and was identified as a system that doesn’t meet the requirements of the Electrical Equipment (Safety) Regulations 2016. The investigation identified that battery cells inside the system that were manufactured by a third party may have contained excessive lithium plating. This can potentially lead to cracking of the cell casing, resulting in an internal short circuit and thermal runaway. Ultimately, these factors could lead to the battery system overheating and catching fire.
The official Government Statement
The official Government Office for Product Safety & Standards report states, “Tesla has remotely discharged most affected Powerwall 2 units pending replacement. Any remaining affected units are being discharged by Tesla technicians. Customers should ensure their Powerwall 2 remains online and check the Tesla app for a notification confirming whether their unit is affected. If a replacement is required, customers should contact their original Tesla Certified Installer to arrange installation. Affected Powerwall 2 units will be replaced free of charge. If the original installer is unavailable, customers should contact Tesla Support on +44 1628 450630 or visit the Tesla Powerwall 2 Replacement Program”.
What have Tesla done?
Tesla themselves have nearly discharged all affected units remotely, notifying customers through the Tesla app about. They said “These units will be replaced at no cost to you. If your installer is unavailable or is requesting additional payment, you can contact the Tesla Support team.”
What does this mean for the customer?
Many homeowners will have questions regarding the safety of their home and how their power storage works while this system is offline. Tesla has said that once a Powerwall 2 is discharged, it doesn’t pose an operational risk, meaning that homes are at no risk of fires from the system. Tesla is also prioritising affected customers during this time, saying that once customers have contacted a Certified Installer, they will coordinate directly with the installer to schedule removal and installation. For those wondering if their solar will still work without the Powerwall 2, Tesla has said that solar generation will continue, but backup power will temporarily be unavailable until the replacement is installed.
