LG Chem extends ESS recall after concerns with over-heating lithium-ion batteries

LG Energy Solution— an LG Chem subsidiary— will extend its scheme to replace lithium-ion batteries used in its home energy storage systems (ESS) to include all geographical markets.

LG Energy Solution— an LG Chem subsidiary— will extend its scheme to replace lithium-ion batteries used in its home energy storage systems (ESS) to include all geographical markets.

ESSs manufactured between April 2017 and September 2018 are being recalled due to overheating concerns.

The latest scheme expands on similar programs in Australia and the US.

The Korean firm— launched last December by LG Chem— will replace batteries with others that “incorporate manufacturing process improvements that further enhance the safety of its ESS batteries” for free.

All proposed safety measures, including the replacement of the potentially affected ESS batteries, will take place after consultation with customers.

LG Energy Solution will implement remote modifications to the affected batteries, where possible, to reduce the potential for overheating while owners of the affected ESS units wait for their replacement units.

In addition, the firm will update its battery diagnostic and control software. 

Earlier this year, the Korean battery giant made a safety recall over concerns its Resu-branded residential ESSs installed in Australia could overheat and catch on fire.

These concerns came just months after a similar recall in the US, with the company working with the U.S. Consumer Product Safety Commission (CPSC) following reports of five fires with its battery systems.

The latest recall in the UK involves LG Chem’s RESU 10H lithium-ion storage battery that have been installed as part of a residential energy solar panel system.

The serial number of the recalled product begins with R15563P3SSEG and is located behind the access door of the RESU 10H (Type-R) home battery.

A newswire statement from LG Chem read: “LG Energy Solution conducted a review of its manufacturing and quality assurance processes in relation to reported incidents that occurred due to the overheating of the batteries subject to this program. 

“Based on its review, LG Energy Solution has determined that there were certain issues in the early production processes for electrodes used in these potentially affected ESS batteries. “

Economics of second-life lithium ESS years from adding up

Mon, 11/28/2016 - 10:03 -- Xuan Zhong

The economics of reusing batteries from plug-in vehicles for residential energy storage systems (ESS) doesn’t make sense, at least according to technology analysts Lux Research.

Lux came to the conclusion after comparing a residential 11.2kWh ESS system using second-life batteries at around $4,600 against a new 7kWh system, at $6,000.

Flow battery partnership to target major ESS markets

US firm ViZn’s zinc and iron flow battery will be used in turnkey large-scale energy storage systems (ESS) following a deal with a vertically integrated utility-scale renewable energy firm.

The strategic partnership with US company Alpha Energy will see the Texas-based firm’s technology used for large behind-the-meter, grid-edge and utility-scale front-of-the-meter applications.
