Tesla has recalled approximately 10,500 of its Powerwall 2 home battery systems in the United States due to a fire risk, which was initiated after the company received 22 reports of the units overheating.
These incidents included six cases of the batteries emitting smoke and five instances of fire resulting in minor property damage. The issue is attributed to a defect in the lithium-ion battery cells, sourced from a third-party supplier, which can cause the system to stop working and overheat. This recall affects Powerwall 2 units sold between November 2020 and December 2022 and is similar to a recall for the same issue was issued in Australia two months prior.
Context
The Tesla Powerwall is a rechargeable lithium-ion battery system designed for home energy storage.
Launched in 2016, the Powerwall 2 is Tesla’s second‑generation rechargeable, lithium ion battery system designed for residential home energy storage and typically paired with rooftop solar to store electricity for self‑consumption and backup during outages. Compared to generation 1, it offered a significant increase in energy capacity to 13.5kWh and sits within an energy division that has become a significant and fast-growing revenue source for Tesla.
Lithium‑ion batteries, while efficient, can present thermal‑runaway risks when defective cells overheat, which is why recalls are coordinated with safety regulators like the CPSC.
Tesla commonly uses over‑the‑air controls to manage energy products and initiate safety mitigations (like remote discharge) before physical replacement.
