What are OEMs to do? For starters, they can partner with an automotive technology partner that takes safety as seriously as they do. Let’s take a closer look at three ways Aptiv is helping lower the risk in EVs, even as the voltage inside them increases.
Safety for everyone who touches the car
When it comes to electrical wiring and high-voltage connections, Aptiv builds safety into every design. Every Aptiv connector must pass the "finger-proof" test, meaning the design makes it impossible for someone to touch any internal portion of the metal electrical contacts. This is an important design feature that protects a consumer or a service technician who might accidentally or intentionally gain exposure to an open connection.
Aptiv also is a proven leader in fuse-in connectors and other innovative technology that ensure that if a spike in current reaches a potentially dangerous level, the battery will disconnect from the rest of the car and the charger, thus eliminating any potential for a catastrophic event.
Similarly, in scenarios where a connector may be accidentally disconnected while the power is still on, Aptiv’s embedded High Voltage Interlock Loop (HVIL) technology serves as a kind of circuit breaker embedded directly in the connector, effectively putting the car into “safe mode.”
Industry-leading reliability and safety
Another way Aptiv lowers risk even when voltages grow higher is by exceeding the highest safety specs set by OEMs. Most specs cover vehicles in the 600V to 750V range, but Aptiv designs its products for 1000V, making them not just safer for today’s EVs but also ready for adjacent markets right around the corner, such as electric buses. Additionally, Aptiv exceeds by double the OEM requirements for reinforced isolation of high-voltage connectors to minimize unwanted transient currents.
Truth in testing
Our Failure Mode & Effect Analysis (FMEA) methodology allows us to design and control parameters that can anticipate a broad range of safety issues. Functional analysis, from design and prototyping through manufacturing and production, is how we find the answers we need to guarantee that every EV component we deliver to an OEM meets or exceeds its established safety requirements.
