Goodbye Old King Coal Generation.

A couple of interesting pieces from E&T.


The first on the problems of using EVs in cold weather:

https://eandt.theiet.org/content/articles/2020/02/how-to-stop-cold-weather-decimating-the-range-of-your-electric-vehicle/


Both pre-conditioning and smart charging assume that you have your own dedicated charging point.


The second is on recycling EV batteries:


"That high level of risk continues into the decommissioning phase, but is reduced as the packs are broken down to a modular level where voltages are much lower; it’s a safer prospect to work with 20 30V modules than a single 600V battery.

However, the reverse logistics of breaking down an electric battery are complex. At present it involves a specially trained technician wearing specific arc-flash-proof protective clothing and using insulated tooling. Risk assessment and method statements make the process as safe as it can be, but even with such protocols the danger of fire and electrocution is very real. Away from these obvious hazards, the handling of a battery that can weigh more than 600kg mass is awkward and sometimes easier said than done, especially when it is heavily damaged with componentry fusing together after a heat event."
