What is high voltage connector?

What is high voltage connector?

High voltage connectors (HV connectors) are typically used in AC, DC and RF applications that experience high voltage. These connectors make it possible to transmit signals with high voltage ratings without posing safety risks to operators. Any connector above 1 kVAC is considered high voltage.

What is a low profile connector?

Carlisle Interconnect Technologies (CarlisleIT) Low Profile connectors are a compact and lightweight solution where weight, space, and/or EMI shielding are critical. Utilizing Plated Composite Thermoplastic materials they offer approximately 15-20 percent weight savings.

What material is used for high voltage connectors?

Silicone – still the best material for high voltage connectors. Silicone remains the go-to material for high voltage connectors and cable assemblies.

What is HVIL loop?

HVIL, or high-voltage interlock loop, is a safety feature of hybrid and all-electric vehicles that protects people during the assembly, repair, maintenance and operation of a vehicle.

What happens if there is any disconnect in the HVIL circuit?

Since there is a risk that an accident like an electric shock will occur if the HV connector is disconnected, a high-voltage interlock device is necessary to provide the connector with an interlock loop to help detect the poor connection of the HV connector due to open circuit.

What is high-voltage interlock?

Interlock is a current and voltage loop mechanism used to detect tampering or opening of the high-voltage equipment or service disconnect switch. This design covers generating and monitoring mechanism of high voltage interlock system.

Is HVIL a high-voltage circuit?

HVIL uses a continuous, low-voltage loop that monitors all high-voltage connectors and components in an electric vehicle (EV).

What is HVIL monitoring?

High Voltage Inter-lock (HVIL for short), a safe design method for monitoring the integrity of high-voltage circuits with low-voltage signals. Theoretically, the low-voltage monitoring circuit is connected first and then disconnected than the high voltage, and the necessary advance is maintained in the middle.

Why do hybrid and electric vehicles use high-voltage in their drive system?

Most new hybrid vehicles now include a 48-V system, and standard vehicles with internal combustion engines are moving in that direction. As for EVs, all require high voltage to power the motor. Voltage levels of 400 to 800 V or more are needed to generate sufficient power to run the vehicle.

What is interlock circuit?

An interlock device is designed to allow a generator to provide backup power in such a way that it (a) prevents main and generator power to be connected at the same time, and (b) allows circuit breakers to operate normally without interference in the event of an overload condition.

Why is 800V better than 400V?

800 volts is faster because it lowers the current; the lower the current, the lower the resistance (energy) loss in the conductors. 800 volts is simply more efficient than 400 volts, experiencing less energy loss for the same amount of power consumed. 800V is double the voltage of 400V.

Why is higher voltage better in EV?

A higher voltage system allows a lower current to be used when charging the battery, which reduces overheating and allows better power retention in the system. This power can be used towards a longer driving range.
