China’s loaded volume of power batteries reached 28.3 gigawatt-hours in May -- an on-year increase of 46.8% and an on-month increase of 11.4%, Kallanish learns from the Power Battery Application Committee of China Industrial Association of Power Sources.

CATL, BYD and CALB were the top-three firms in the NEV battery market in May, with installations of 11,789 megawatt-hours, 8,695 MWh and 2,185 MWh, respectively. 

During January-May, the loaded volume of power batteries in the Chinese market reached 121.3 GWh, an on-year increase of 44.2%. In the period, CATL held a market share of 43.2% with a cumulative loaded volume of 52,417 MWh; followed by BYD with a share of 30.6% and 37,115 MWh of loaded batteries. CALB’s share stood at 8.1% with 9,835 MWh deployed.

In terms of battery type, in the first five months of this year, the total loaded volume of lithium iron phosphate (LFP) batteries reached 80.7 GWh, a 66.5% stake of the total loaded power battery volume; and the loaded volume of ternary batteries reached 40.6 GWh, a 33.5% stake. 

Eve Energy had the highest increasing speed among the top-10 power battery firms in terms of power battery loaded volume with an increase of 171% during the five-month period. It is currently the fourth-largest battery company on the list.

BYD is also shortening its gap with CATL in terms of market share, however, its market share increase is mainly due to the surge of its new energy vehicle sales. So far, its outsourcing is below expectations, according to the committee.
