The BSG technology has the greatest advantages of small change to the whole vehicle and limited increased cost. Taking the case of the Chery A5 equipped with the BSG, the manufacturer prices are 7.48 ten thousand yuan, and compared with the ordinary A5 with the price of 6.98 ten thousand, the price is increased by about 7 percent, thereby creating conditions for the ordinary consumers to purchase BSG vehicle models. Moreover, with the expansion of market scale, the application cost of the BSG technology is expected to be further reduced, and when the price difference between the BSG vehicle type and the price of the traditional power vehicle of the same type is reduced to a certain degree, the cost factor of the BSG technology can be almost ignored.
