TE's New Current Sensor

High Reliability, Flexible Design

NOVI, Mich. – TE Connectivity (TE) released a new automotive current sensor this week for the hybrid and electric vehicle market at The Battery Show 2016 in suburban Detroit.

TE's new Coreless Current Sensor is an addition to a lineup for the automotive industry that includes position, speed, humidity, pressure, and temperature sensors, among others, and furthers the company’s position as a leader in high-voltage (HV) transmission and distribution.

The company's hybrid and electric mobility solutions include a complete line of connectors, terminals, sensors, cable assemblies, contactors, and battery connection protection to help safeguard the flow of power in hybrid and electric vehicles. And TE is well-positioned to accelerate success for car makers seeking a leadership role in the connected car market.

All of TE’s portfolio in hybrid and electric mobility solutions and sensors were on display at The Battery Show at the Suburban Collection Showplace, where the company’s leaders and experts were available to answer questions.

The Battery Show, held over three days just outside Detroit, is a showcase for the latest advancements in battery, hybrid and electrical and related sensor technology. It’s attended by technical leaders, scientists, engineers, media, project leaders, buyers and senior executives from companies around the world.

‘’It makes perfect sense to release our new current sensor here,’’ said Scott Phillips, TE’s Senior Manager for Automotive Sensor Products.  ‘’This is where the experts are. Our new sensor is designed specifically for these types of battery packs. This is the best place to talk to the end users about this product.’’

Designed for EV Market

Phillips said the Coreless Current Sensor has been developed to be highly accurate while being highly reliable. It boasts a compact size intended to fit into battery pack disconnect units and has a flexible design that can meet customer design needs.

‘’This current sensor is designed for the EV market,’’ said Phillips. ‘’In that space you have to be able to measure current extremely accurately over a large range. A Lithium Ion battery pack can pump out close to 2000 amps of current in a short-circuit condition. You don’t want that to happen. You have to protect yourself.’’

Typical applications include,

·       Standard battery monitoring.

·       Hybrid and EV battery pack current sensing.

·       Fuel cell current control.

·       DC/DC converters and AC/DC inverters.

·       Hybrid and EV motor inverter drive.

·       And EPS and X-by-wire applications.

Phillips called the release of the new sensor the latest in what has been a series of technical advances in the Hybrid and EV market, all huge positives for the consumer.

‘’There is a coolness to this technology when you look at what some of the automakers are doing on the premium end of the market,’’ he said.

From the engine to the transmission to the rear bumper, cars and light trucks on the road today have an average of 55 sensors built into them that serve to do everything from protect drivers during hazardous conditions to monitoring engine performance and emissions.

And that number, said Phillips, is likely to grow to 65 sensors by the 2020 model year as automakers design vehicles aimed at being safer, more fuel efficient, less polluting, and better able to communicate critical information to drivers.
