Electrical Arc Monitoring & Protection System

Request Number N469760
Need details
Description

IncWell's partner seeks the ability to detect and, ideally, prevent electrical arcing events in a 48V system.

 

Background

In modern automotive electrical systems, electricity nominally flows at 12V with the possibility for the voltage to increase to as high as 48V, creating an unsafe operating condition for the power net system.

 

In this situation, the potential exists for arcs of current (at temperatures ranging from 7000 K - 20,000 K) at poor conduction sites. These arcs can cause functional failures of the overall electrical architectures and, in a worst case scenario, result in a fire hazard for the vehicle and its occupants.

 

Potential areas for damage include:

 

 

 

 

 

 

 

 

 

This diagram shows that, at 48V and a current higher than 0.9A, stable electric arcs are capable of forming in the air, depending on sparking distance:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

As a result, we are seeking a safe, cost effective and weight efficient technology that will have the capacity to sense and, if necessary, prevent electrical arcing events within an automotive environment.

 

Key Success Criteria

The successful monitoring system will have the ability to: 

  • Recognize electrical arcs and communicate them to the vehicle

OR

 

  • Recognize electrical arcs, communicate them to the vehicle AND have a mechanism to interrupt the current flow.

 

Additionally, the technology should be well developed and nearing implementation readiness (Minimum TRL level =  6).

 

Possible Approaches

IncWell's partner is open to any technology capable of achieving the criteria described above, including, but not limited to:

  • Connector-monitoring (Connector is not removable under load)
  • Detection of electrical arc through load detection of electrical consumers

 

Approaches not of interest

While IncWell's partner is open a variety of potential approaches, they are not interested in solutions that include only passive arc prevention technology without the ability to sense and report the arc event.
