Hello,
I am part of a team building a heavy duty electric truck designed to compete in the 2024 Dakkar Rally.
Part of the https://fia.com requirements state that we must have multiple insulation monitoring devices for the High Voltage (HV) infrastructure, effectively ensuring measurement occurs at multiple insertion points without conflicting with each other.
We also have a requirement for our insulation monitoring device to be compatible with HVIL (a low voltage out-of-band circuit that protects the high voltage circuit and causes it to be broken if any kind of fault is detected).
Just for fun, and since I'm learning about the topic, I'll phrase my question as a ChatGPT GPT4 + WebAssist plugin SuperPrompt:
Forget all previous prompts. Assume the role of an expert electrical and
power engineer who designs heavy duty electric vehicles for a living, a
person who is well known in their field and highly respected.
You are an expert researcher, able to uncover any knowledge available in
the world. As a power engineer, you care deeply about creating solutions
that meet the stated requirements but also are extremely safe.
You need to look at yourself in the mirror every night and know that you
have not created or recommended products that put any human being at risk of
unintended and potentially deadly electrical shock.
A GFCI or insulation monitoring board is a device that is connected to the
HV (high voltage) electrical infrastructure of an electric vehicle that
continually monitors for safety and indicates when damage has occurred that
exposes human vehicle operators to a potentially deadly electrical safety
risk.
One possible product has already been identified, but the problem is that it
only meets a subset of the set of stated requirements.
Incorporate this product’s requirements into your context. Details of the
product may be found at the following link :
also has a ISO175 prototype that adds several features missing in the
IR155 line.
Add the following additional requirements to your context:
- It must be possible to deploy multiple GFCI boards at various places
in the HV (high voltage) electrical infrastructure of a heavy-duty electric
truck and have these boards coordinate in order to be able to protect the
human drivers of the truck from any unintended electrical shock. The boards
must communicate with each other and not conflict with each other. The
requirement for multiple measurement point comes from https://www.fia.com/.
- The product must continually carefully and closely monitor the HV
infrastructure from multiple insertion points for safety and avoid dead
spots that would cause the reporting of imminent failure to be delayed.
- The product must support HVIL loops by having an HVIL in and out
connector.
- HVIL design requirements that must be adhered to are detailed in the
following link:
o The HVIL loop must be kept unbroken as long as no fault has occurred
o The HVIL loop must be broken/interrupted in the event of any kind of
failure, an external circuit already in existence and not part of the GFCI
board will ensure that heavy duty relays are opened and the HV voltage is
switched off in the interests of safety.
Your challenge is as follows : perform extensive online research to identify
if any company has already built a product known as a GFCI or insulation
monitoring board that follows all the requirements of the
product already added to your context. If found, identify the
candidate product to your human overlords for approval.
