Nov 13 (Reuters) - Tesla said on Thursday it is

recalling about 10,500 units of its Powerwall 2 battery power

systems in the U.S. for fire and burn hazards after receiving 22

reports of overheating.

The U.S. Consumer Product Safety Commission said the recall

covers systems that "may fail and overheat," raising the risk of

serious injury or death, though no injuries have been reported

yet.

The Powerwall 2 is a residential energy-storage unit that

integrates with solar-panel systems, storing electricity for

self-consumption, shifting usage to lower-cost periods and

providing backup in grid outages.

The defect stems from certain lithium-ion battery cells that

may overheat under certain conditions, smoke or ignite. In a few

cases the defect has caused property damage, according to the

recall notice.

Tesla said it is remotely limiting the charge on affected

units to minimize risk while it arranges free replacements for

customers.

The recall draws attention to Tesla's battery-cell suppliers

and comes as its energy-storage business plays a growing role in

the company's expansion beyond electric vehicles.
