Chana Auto launches China's first electric-only powered vehicle

Benni-I electric cars, China's first electric-only powered vehicles, started rolling off the production line at Chana Auto Company's Chongqing Yubei Plant December 6. This model will be officially put on sale in the second half of next year, said Chana Auto president Xu Liuping.

Same appearance with gasoline-powered model

The Benni-I electric car is an internationally advanced, high-speed, electric-only powered car developed by Chana's 200-member professional team after two years of research and development. The car has outstanding features such as zero emissions, low energy consumption and high performance. Every function and specification of the entire car is at a leading level both domestically and also globally.

The fuel tank at the rear of ordinary gasoline-powered cars is replaced by a special electrical socket, while the traditional gasoline engine is replaced by a permanent magnetic synchronous AC motor, a set of high-performance lithium batteries, radiators, storage batteries and a charging system. The main driving forces of the Benni-I car are a battery pack composed of 100 lithium iron phosphate batteries which weighs 300 kilograms and a PM brushless DC motor.

The car is expected to enter ordinary households in five years

Xu told reporters that the comprehensive cost of Chana's electric car is higher than that of an ordinary gasoline-powered car by 100,000 yuan to 150,000 yuan. Electric cars are unlikely to enter ordinary households unless there are technological breakthroughs in lithium batteries and the mass production of electric cars, as well as a certain amount of subsidies from both the government and enterprises in the future.

Wang Jun, assistant president of Chana, said December 6 that at present, the primary cost and technological barrier to developing electric vehicles comes from lithium batteries. Aside from sustained high cost, lithium batteries still have problems such as taking too long to recharge, and having limited battery storage capacity, a short service life and poor heat radiation.

The State Grid Corporation of China (SGCC) is installing facilities such as charging poles and charging plugs in Chongqing's garages, public institutions and other sites. It is expected that Chana's electric-only powered vehicles will be mass produced and formally available to the public by 2015.

Secrets behind the Benni-I car

The Benni-I car has only three gear speeds

In terms of appearance, the electric-only powered Benni-I cars are almost identical to the gasoline-powered Benni-I cars that recently debuted at an automobile exhibition, so they are both called “Benni-I”. As the car has only accelerator and brake pedals and just three speed gears of drive, neutral and reverse, the Benni-I is even more simple and “user-friendly” to drive than AT cars.

The car can run for a maximum of 150 kilometers after being fully recharged

Reporters learned that with an electric-only power system, the Benni-I electric car has a top speed of 120 km/h and takes 16 seconds to accelerate to 100 km/h. The electric car requires half an hour to recharge in quick charge mode and six hours in slow charge mode. The car is able to run for a maximum of 150 kilometers after being fully recharged and consumes only 10 kWh per 100 kilometers, with zero emissions.

The car's running costs are one third that of a gasoline car

A 1.6-liter gasoline car for example generally consumes seven liters of gasoline per 100 kilometers, so calculated on the basis of the average 6.4 yuan price of 93 gasoline, it costs about 45,000 yuan to run 100,000 kilometers. The current cost of residential electricity is 0.54 yuan per kWh and the electric car consumes 10 kWh per 100 kilometers. Added with eight yuan of depreciable cost per 100 kilometers of lithium iron phosphate batteries and 3,000 yuan of maintenance fees, the cost of running the electric car for 100,000 kilometers is around 16,000 yuan.
