BANGKOK (Reuters) - As sales of electric vehicles miss expectations in Southeast Asia's largest market, Thailand's main group of manufacturers, comprising large Chinese and Japanese firms, seeks to extend production deadlines set in a government scheme of incentives.

The scheme helped lure investment of more than $1.44 billion in new production facilities from Chinese EV car makers, such as BYD Motors and Great Wall Motor, making Thailand a regional hub in turning out electric vehicles (EVs).

But as sales falter, partly because Thai banks have tightened loan requirements, the Electric Vehicle Association of Thailand (EVAT) is asking the government for more time to meet targets in the main incentive scheme supporting the industry.

"We're trying to negotiate, extend the production date out a little," the grouping's president, Suroj Sangsnit, told Reuters, outlining a proposal that has not previously been reported.

"The conditions say we have to produce within a year, so can we ask for another year?" added Suroj, the executive vice president of SAIC Motor-CP, a joint venture of SAIC Motor and Thailand's CP Group.

The EV 3.0 plan, as it is called, required companies receiving tax breaks and other support to produce in Thailand this year the same number of vehicles they imported between 2022 and 2023.

Missing the deadline sets them a tougher task next year, as the scheme binds them to produce 1.5 cars for each imported vehicle.

Major Chinese companies pushing for the change include BYD, MG Motor, which is owned by SAIC Motor Corp, and Great Wall Motor, Suroj said.

BYD and Great Wall Motor did not respond to a Reuters request for comment.

Seeking the concession is one tactic in a broader push by the EV industry to manage lower-than-expected sales, as part of which they met Thai central bank officials this year.

Narit Therdsteerasukdi, secretary-general of the Thailand Board of Investment, which runs the incentive scheme, declined to comment without receiving guidance from the cabinet of new Prime Minister Paetongtarn Shinawatra.

Thailand has long been a hub for auto making and export, dominated by Japanese brands such as Toyota Motor and Honda Motor, which are also members of EVAT.

The government incentives for EV production aim to spur conversion of 30% of the annual output of about 2 million vehicles to electric vehicles by 2030.

New EV sales this year stood at 43,000 and were likely to miss EVAT's target of 100,000, Suroj added.

They reflect broader weakness in the Thai auto industry, where car production contracted 17.28% in the first seven months of 2024 from a year earlier to stand at 886,069.
