Battery Electric Vehicle Platforms

Technology Roadmap Sections and Deliverables

• 1BEV - Battery Electric Vehicle Platforms

The Battery Electric Vehicle (BEV) platform, a level 1 roadmap, is a segment of the broader automotive market. Level 2 roadmaps represent the critical product/systems to that are integrated within an electrified platform. Level 3 roadmaps represent critical subsystems within an electrified vehicle, and level 4 roadmaps would indicate an individual component technology roadmap.

Roadmap Overview

Electrified vehicles (PHEV, BEV, FCV, etc.) are vehicles that utilize electric power (from a variety of different sources, such as batteries or fuel cells) to power an electric motor-based propulsion system. Electrified vehicles are an increasingly popular alternative to traditional gas-powered vehicles that generate propulsion through internal combustion engines. Electrified vehicles are one part of a broader ecosystem of solutions being used to combat the evolving problem/challenge of climate change. Electric vehicles help to solve this problem by providing humanity with an alternate mode of transportation that does not produce harmful greenhouse gas emissions.

This roadmap will focus specifically on the battery electric vehicle (BEV) platform. BEV platforms are becoming increasingly popular as consumers seek different options within the electric vehicle market, and manufacturers look for ways to meet this customer demand through the use of modular architectures that multiple different vehicle variants may be built upon. Modular architectures / platforms for battery electric vehicles are typically comprised of a battery pack, on board charging module, integrated power electronics, drive units, and a chassis will a wheel base. Multiple different vehicle bodies and accompanying features may then be built upon these platforms. Below are two examples BEV platforms being produced today (one by Tesla Motors, and one by General Motors).

Roadmap Model using OPM

We provide an Object-Process-Diagram (OPD) of the Battery Electric Vehicle (BEV) Platform in the figure below. This diagrams captures the main object of the technology (Battery Electric Vehicle), the value-generating processes and different instruments associated with their characterization by Figures of Merit (FoM).

An Object-Process-Language (OPL) description of the roadmap scope is auto-generated and given in OPL_Battery_Electric_Vehicle. It reflects the same content as the previous figure, but in a formal natural language.

Figures of Merit

TBD

Figure of Merit (FOM)	Unit	Description
Vehicle charge rate	[KW/hr]	Rate at which energy is added to the vehicle’s battery pack during charge
Motor Efficiency	[%]	Percentage of energy discharged from the battery pack that is converted to mechanical energy
Motor Torque	[N.m]	Torque produced by the electric vehicle motor
Kilometers per kilowatt	[km / kw]	The average distance the vehicle travels based upon the amount of energy used
Range	[km]	The number of miles the vehicle can travel on a single full charge
Acceleration time	[s]	Text
x	[x]	Time to accelerate to from 0 to 100 km/hr (km per hour)
