Interesting QuestionHas anyone ever seen or thought about including a crash sensor safety switch? something like this:
Inertia Crash Sensor Switch
Something to ensure no HV coming out of the junction box in the event of an impact. Easy to reset by the driver if triggered accidentally by a low speed bump...
My answer may well be controversial (but please be nice 😆 ) .. short answer: no
Let me explain, based on experiences with my 1st conversion, an early RHD smart car. This was ideal as small and quite light and with a massive hollow floor, designed for batteries - Lead acid in this case as Lithium was still too new and costly in those days.
The car cut out when my wife was diving – over a bumpy busy level crossing (railroad crossing in the US). Wife in panic mode
Lesson - I now only use waterproof control wiring with a minimum of crimped and soldered connections, and the minimum number of ‘safety’ cutouts.
IMHO reliability along with primary safety (eg power, brakes, handling) must trump multiple safety contactors and cut-out switches and especially crimped connectors.
