What is the EV Energy Density Assessment?

• The assessment provides a monthly weighted average of battery pack sizes across the EV industry, based on an analysis of the following vehicle classes:

• Passenger Car & Light Duty vehicles

• Buses and Coaches

• Medium duty commercial vehicles

• Heavy duty commercial vehicles

Assessment methodology

Rho Motion’s EV Energy Density Assessment is a weighted average of vehicle battery packs 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 75% 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. Heavy and Medium duty data is supplied by powertrain specialist consultants Knibb, Gormezano & Partners (KGP) who have been tracking vehicle markets and providing technical consulting in automotive and related sectors for 30 years.
