from chemistry to pack
Author: Dominic Pascal Förstermann, Akkuracy Battery chemistry choices affect everything from product safety certifications to insurance and procurement decisions — yet the common viewpoint remains “LFP is safe, NMC is dangerous.” But is that actually true? This article looks at the empirical data. In order to describe the safety aspects fully, it is split into … Read more
The Fireman Access is being touted as a significant safety feature and as such Renault have made all of their patents on the technology freely available. In fact Renault are granting free access to all of their electric vehicle safety patents [1]. Renault Fireman Access is an exclusive innovation allowing emergency services to put out … Read more
Electrolyte detection is a possible way of seeing early cell failures where a soft vent results in electrolyte being vented and dispersed into the pack volume. This soft venting of electrolyte happens prior to a cell going into thermal runaway. Liu et at [1] look at the development of an electrolyte sensor that measures Ethyl … Read more
There are many different ways of triggering the thermal runaway of a battery cell, primarily grouped as: Within these groups, legislation has offered a nail test, external heating pad and the electrical short circuit. All of these methods have pro’s and con’s. Hence the search for a more repeatable and realistic trigger method. The Cell … Read more
