In 2020, the installed capacity of NEV batteries in China reached 63.3 GWh, and the market size reached 61.184 billion RMB, gaining support from many governments.
In recent years, the explosive development of NEVs has led to increasing demand for NEV batteries, which has led to the rapid development of the NEV battery industry, resulting in increasing prices of raw materials manufactured and sold by raw material manufacturers, i.e., the upstream battery industry.
Lithium batteries have been widely deployed and a vast quantity of battery data is generated daily from end-users, battery manufacturers, BMS providers and other original equipment manufacturers. Two elements are key in enabling the value of data: accessibility and ease of use.
