Chinese automaker and rechargeable battery manufacturer BYD Company has recently received consumer complaints about insufficient endurance of batteries for one of its electric vehicle models, according to a report from the Beijing-based Legal Weekly.

The problematic batteries are from its BYD Qin model, a second-generation Dual-Mode, plug-in hybrid compact electric sedan with an all-electric range of 70 kilometers and a hybrid electric powertrain that is said to be able to extend the car's total range to a distance similar to that of a conventional gasoline-powered vehicle, the report said.

Ten out of the 25 complaints against BYD filed by owners between June 24, 2014 and June 6, 2015 were about its electric vehicle batteries, with major problems stemming from the real driving range of its electric cars being less than the company originally claimed and an insufficient remaining charge in the storage batteries.

The cost and capacity of battery packs has been a key problem hindering the development of the electric vehicle industry. The industry has yet to determine if lithium iron phosphate batteries or grapheme batteries are optimal for electric vehicles, according to industry analyst Wang Gai.

The BYD Qin uses a 13 kWh lithium iron phosphate battery (LiFePO4) pack to provide energy storage.

The Qin has enjoyed strong sales in China since it was launched last year. The model accounted for 27.9% of the Chinese new-energy vehicle market and 49.6% of the plug-in hybrid automobile market.

In the first quarter of this year, the share of BYD's electric car batteries in the global market climbed from 6% to 9% from the same period last year.

The Qin is currently available in China and in Latin American markets and senior company executives have discussed expanding the exports of the new energy vehicles in coming years.

However, an industry analyst said that the recent complaints about BYD's batteries show that it may have brought out Qin too early to be technically prepared for the launch. The hurried launch might have occurred because BYD was in a rush to get government subsidies for new energy products, according to the analyst.
