Kunshan Jin Xin New Energy Co., Ltd. (872380) is mainly engaged in the research, development, production and sales of battery management software and lithium-ion battery modules and accessories. The development trend of new energy industry in Jin Xin: the low energy density and poor low-temperature performance of lithium iron phosphate batteries lead to poor endurance of new energy vehicles, which is difficult to meet policy subsidies and consumer demand. From the perspective of industrial chain, the new energy vehicle market will present a three-legged situation of battery manufacturing enterprises, three-party contracting enterprises and complete vehicle enterprises.
