Bosch Battery Systems assembles lithium-ion battery packs for automobiles.

Initially Thursday, a Bosch government relations manager confirmed to the Dayton Daily News that she had contacted state and regional elected officials regarding plans to lay off 65 workers. She referred further questions to a colleague.

Emails between the governor’s office and regional jobs offices obtained by this news outlet outlined the company’s plans.

However, at about 1:30 p.m. Thursday, no new WARN (Workers Adjustment and Retraining Notice Act) letter from Bosch was shown on the Ohio Department of Job and Family Services web site.

There has been a history of layoffs at that site.

In May 2017, Bosch Battery Systems said it intended to lay off 88 workers due to a “significant downturn in business.”

The company also laid off about 74 workers in 2015.

The automotive battery plant is at 50 Ovonic Way, a cul-de-sac off North Pioneer Boulevard in Springboro.

Originally known as GM Ovonic, Bosch acquired the former Cobasys plant from SB LiMotive, a joint venture of Bosch and Samsung, in October 2012.
