Third installment on Canadian research into EV battery durability.

Road map for Transport Canada’s research plans on Electric Vehicle Safety with NRC

Outlook format (.msg) e-mail file summarizing Canada’s NPRM and responses. It is anticipated that a Canadian proposal will be published in early 2019 to permit the proposed option of compliance to either the US or UN standard.

Update on Transport Canada VRU collision research.

Summary of initial Transport Canada research into the impact of vehicle use on electric vehicle battery performance and driving range. The research quantified losses in charging energy, useable battery energy, and driving range as travel distance rose.

US and Canada position on the draft fire exposure test for electric vehicles. Pursuant to Canadian testing, the US and Canada do not see a need for additional testing of electric vehicles (as opposed to ICE vehicles) because the battery and electric systems do not show any cause for special concern in vehicle fires. Battery pack testing could be considered in a later phase in the development of the safety regulation if warranted.

Revised presentation on a research project intended primarily to evaluate regenerative braking energy and CO2 emission differences between a 2-wheel dynamometer, a 4-wheel dynamometer and empirically determined rear-axle braking forces applied the same test conditions on a 2-wheel dynamometer. The expectation is that the two-wheel dyno tests will produce the highest regenerative braking energy and lowest CO2 emissions since it places 100% of the braking load on the rear axle.

In Australian and Canadian testing, the WorldSID 50th percentile male dummy responses indicated a significantly lower AIS 3+ thorax injury risk for the Canadian vehicle. This presentation includes further results and analysis to investigate and explain the differences.
