I have met Joakim Hansson who works at DEKRA. There he is the product owner for their battery test service and in the video he talks about what he has learned about batteries since DEKRA started doing battery tests. He explains how to test batteries, the disadvantage of only reading the BMS, what differentiates different battery types and much more. This is more listening than watching but I hope you find it as interesting as I do. 00:00 - Intro 00:26 - What is battery test from DEKRA? 01:09 - How does it work? 02:49 - Can SoH be trusted? 04:26 - Battery test 07:10 - Review report 10:38 - Which cars does this work with? 13:27 - How big is the database? 13:54 - How long does a battery last? 17:09 - What is okay health on a battery? 19:22 - Do you dare to buy a used electric car? 20:54 - How do you take care of your battery? 24:00 - Can you just fast charge your electric car? 24:43 - How do you kill your battery? 25:28 - How does an LFP battery work? 28:29 - Is 80% best for NMC? 29:08 - Degradation of different battery technologies 32:48 - Can the car last a night on a charge? 33:50 - The consumer purchase law when buying a used electric car -- Good links -- Avoid advertising and watch videos a week before others: / electric car magazine Do you like what I do?
