TOKYO (Reuters) - Panasonic Corp said on Tuesday it expects its battery business supplying Tesla Inc to be profitable this fiscal year, and raised its full-year operating profit forecast by more than half. After several years of production troubles and delays at Tesla, Panasonic is beginning to see its decade-old partnership with the U.S. company become a profit driver. Panasonic announced in October that it was developing a new battery cell designed by Tesla, one that would help Tesla halve battery costs and ramp up battery production 100-fold by 2030. “From the next business year we want to end the question of whether (the Tesla) business will be profitable or not,” Chief Financial Officer Hirokazu Umeda said on a call.

The Japanese electronics conglomerate is also planning to add a new production line at the Nevada factory it owns with Tesla, and is looking at building a lithium-ion battery business in Norway in a bid to tap European carmakers. Panasonic plans to start test production for the new line - for Tesla’s 4680 battery - in the financial year beginning April 1, Umeda said. The Japanese company, which gets revenue from product lines ranging from bicycles to hair dryers, said it was also benefiting from pandemic-driven buying of home appliances and sales of 5G equipment. But these were offset by weakness in businesses such as in-flight entertainment systems. Its new forecast of 230 billion yen ($2.2 billion) for the year to end-March - up from 150 billion yen - is still 22% below the previous year. More than a third of that profit will come from sales of appliances. Under outgoing Chief Executive Kazuhiro Tsuga, Panasonic has shifted away from its low-profit home electronics business to focus on housing fixtures, car electronics and batteries for electric vehicles.
