The EV Battery Chemistry Monthly Assessment
Rho Motion’s EV Battery Chemistry Assessment is a weighted average of vehicle battery chemistry across passenger car and light duty vehicle, bus and coach, and medium and heavy duty vehicle sectors.
Electric vehicle sales data is collected on a model-by-model basis from automotive associations at country level for both BEV and PHEV vehicles for major markets. This analysis covers a minimum of 90% of total global market sales, and provides a balanced representation of markets with different vehicle characteristics, suppliers and seasonality.
Where EV specific model data is not explicitly stated estimates are used based on industry and company reports and primary research. These are then corroborated or adjusted when official data becomes available.
For each vehicle model we collect data relating to battery pack size, battery chemistry, cell format, number of cells, and pack supplier in addition to a number of other vehicle metrics.
