Standardization Work for BEV and HEV Applications: Critical Appraisal of Recent Traction Battery Documents

Abstract

Abstract:The increased activity in the field of Battery Electric Vehicles (BEVs) and Hybrid Electric Vehicles (HEVs) have led to an increase in standardization work, performed by both world-wide organizations like the IEC or the ISO, as by regional and national bodies such as CEN, CENELEC, SAE or JEVA. The issues of these standards cover several topics: safety, performance and operational/dimension issues. This paper reports a brief overview of current standardization activities of lithium batteries based on IEC 62660-1/2 and ISO 12405-1/2. Furthermore, in this paper, a series of innovative test procedures for lithium-ion batteries are presented. Thanks to these tests, the general characteristics of a battery such as charge and discharge capabilities, power performances and life cycle can be determined. Then, a new approach for extracting the life cycle of a battery in function of depth of discharge has been developed.

The Kinetic Energy Storage as an Energy Buffer for Electric Vehicles

“…Although this influence is a weak for the Li-Ion batteries, it is estimated in the battery modelling by relation, proposed as standardization work for BEV and HEV applications [31].…”

Examination of the effect of sensor properties on the secondary battery model in simulation environment

Evaluation of the Impact of the Additional Mass of an Innovative AC System on the Overall Energy Consumption of a Battery Electric Vehicle in Tropical Climate

“…Good specific energy, lack of memory effect and slow selfdischarge rates when not in use make lithium-ion batteries a suitable choice for our BEV [12]. To calculate the amount of energy required to drive the vehicle through the 200 km, we calculated the energy required at wheels and back calculated it to the battery through the drivetrain path efficiencies.…”
