Tesla is planning to start manufacturing electric vehicle chargers in China from next year, according to a Reuters report that cites a regulatory filing.

The report said a document submitted to the Shanghai authorities by Tesla says it plans to invest some RMB42m on a new factory to make the chargers, also known as charging piles, near its car plant in Shanghai.

The report also said the factory, which Tesla expects to complete in February, will have capacity to make 10,000 chargers a year, according to the document submitted by Tesla.

Last month Tesla has reported its fifth consecutive quarterly profit and said it is on track to deliver half a million vehicles this year. The company is seeing a ramp-up of Model Y production in the US and Model 3 output at its new Shanghai factory. Tesla said it produced a record 145,036 vehicles in the third quarter and delivered 139,300 vehicles.

Production capacity at the Freemont (Calif., US) facility that makes Model 3 and Model Y has recently been increased to 500,000 a year while the Shanghai factory's manufacturing capacity is put at 250,000 pa.
