The latest episode of Munro Live covers Sandy Munro’s mockup of the VW ID.4 Battery prototype coming from the work we have done with Sabic.
In this episode, Sandy goes over some of the ideas behind creating a practical battery system that will work best for this vehicle, taking the best ideas and attributes of other battery systems we have analyzed.
From keeping the cooling system architecture of the ID.4 but instead building it into the new composite body of the battery housing to the connectors, borrowing load bearing and structural ideas from aerospace projects that we have worked on in the past, comparing larger battery cell designs that are glued to the battery box that actually provide more space for additions and more.
In this fascinating long-format episode, Sandy along with John Waters (Technology and Innovations Leader) from Sabic begin by telling stories about the EV 1 battery tray which both of them worked on in the past. Sandy talks about how the OEM slowed down the process and caused Delco, where John used to work, to jump through several prototype hoops which were unproductive, but eventually the Lean Design, weight-reduced and fire-retardent superior design was chosen.
Moving on, the group meets up with Dave Sullivan (Leader, Americas Automotive Marketing as Sabic) and they walk through the new project and discuss the combined efforts of the group (over 40 people total) who came together for the Munro Sabic and VW workshop as well as suppliers.
The episode then winds through the innovation workshop and highlights the findings and process that culminated in a 53% weight reduction of the battery tray. If you are a product design engineer, you don’t want to miss this episode. Click below to watch the full video:
Munro Does A Teardown Analysis Of The Volkswagen ID.4 Electric Motor
As Sandy points out at the beginning of this video, it is basically unheard of that a company would give us one of their products and permission to teardown and analyze it on our show. Most of the time Munro performs teardowns for companies in private with the data owned exclusively by them, or we choose to teardown a vehicle or product independently in order to sell the information to anyone if we think the technology is interesting or unique. But in this case, Volkswagen has given us permission to walkthrough the process of tearing down their ID.4 Motor on Munro Live.
VW modular concept design regarding the electric motor, housing, bearing shield, inverter and gearbox, allows them to take the ID.4 motor and stick in pretty much any suspensions system to adapt the motor to a variety of vehicles in their fleet. Most likely this choice is made so that they have agility to convert other non electric vehicles to electric in the future. This is a very smart business choice and shows that VW has a keen eye for thinking about their global market reach and creating flexibility.
Sandy points out comparisons with Telsa and other motors we have studies, but the real focus is on pretty much every single aspect of the ID.4 motor itself. If you have ever wanted to know anything about the ID.4 Motor, this 30+ minute video probably covers it, with the exception of cost and certain performance data.
