Tech Focus: Monitoring Battery Temperature by Using a Data Acquisition System or Specialised Battery Test System

Wednesday, January 19th, 2022

In today’s electronics applications, batteries power nearly all of our portable electronic devices. Batteries also serve as emergency power backup systems on large premises. And all-electric vehicles use large cascading battery packs to meet the expected power for the required performance.

In this guest commentary, Bernard Ang from Keysight Technologies shares his insights specialised battery testing.

Batteries are the key to our portable/mobile electronic gadgets in this digital era.

Batteries are the key to our portable/mobile electronic gadgets in this digital era.

Battery packs need the required specific power (W/kg) to be able to dispense enough current to achieve the electric vehicle speed performance.

They also need the required specific energy (Wh/kg) to achieve longer runtime or travel range.

Why is it important to monitor battery temperature?

Most rechargeable batteries today are lithium ion and have an operating range between 15 °C and 35 °C at which their full performance and capacity kicks in.

  • If the battery and its ambient temperature is below 15 °C, you may experience sluggish electrochemical reactions within the battery and as a result, lower battery performance and reduced charge capacity.
  • If the battery or battery pack operates above 35 °C in ambient temperature, battery degradation can accelerate over time. As a result, you may notice shorter battery life, non-uniform aging due to thermal gradients, greater exposure to safety issues, and higher life cycle costs. At extremely hot temperatures, batteries can break down and cause leakage, smoke, fire, and even explosions.

The power map chart below shows the power limits of your lithium-ion battery or battery packs across the temperature range.

For this second half of our commentary, we begin with an introduction of SerDes.

In today’s infotainment systems, it is common for in-vehicle cameras and displays to be connected to the image-processing electronic control unit (ECU) via a SerDes (serializer/deserializer) connection.

Today, they are delivered by individual vendors using closed, proprietary standards.

Extending the reach of feature-rich SerDes links can require operating at lower Baud rates and higher order modulations (e.g. PAM-4).

In addition, it will require higher bandwidth Ethernet links as primary interconnects between zones, perhaps with 802.3ch support up to 10 Gbps throughput.

Emerging SerDes standards like mobile industry processor interface (MIPI) A-PHY (MIPI A-PHY is a physical layer specification targeted for ADAS/ADS surround sensor applications and Infotainment display applications in automotive) and Automotive SerDes Alliance (ASA) will be implemented by multiple silicon vendors.

This will create a competitive market that acts to drive down the cost while delivering application specific features.

It is no secret the pace of innovation in the automotive industry is exploding.

If the last 20 years have been linear in the development of electrification, the last two to three years have been exponential.

It used to be that a car was a means of getting from A to B.

Now, we can safely say that is not true for the vehicles of today and certainly not for the new vehicles of tomorrow.

Just about every new car on the market has a backup camera, park assist, and blind spot monitoring.

Some offer a 360-degree view.

Other features offer real-time traffic updates, cellular connection to potential hazards, other road users, vehicles, or pedestrians.

There are features that can detect if a driver is distracted or tired.

Meanwhile, the people in the car are often unaware of driving conditions, while they enjoy infotainment systems.

These features are delivered through a mixture of sensors, cameras, and networks.

As demands go up, next-generation advanced driver-assistance systems (ADAS) require camera and radar systems with increasingly high resolution.

Tech Focus: C-V2X Certification – Necessary or Just Nice to Have?

Monday, November 22nd, 2021

Fewer accidents and greater road safety are central to the vision for automated vehicles (AVs). Enabling that vision requires greater situational awareness and the ability to inform the car and its drivers what is happening a mile in front of them, foreseeing what’s likely to happen next, and automatically taking preemptive actions.

In this guest commentary, Cheryl Ajluni from Keysight Technologies shares her insights into C-V2X certification.

Cellular vehicle-to-everything (C-V2X) technology provides see-through, 360-degree, non-line-of-sight (NLOS) sensing in good, as well as adverse weather conditions to enhance the functionality and safety of autonomous driving (see the cover illustration).

C-V2X complements line-of-sight (LOS) sensors such as radar, lidar, camera, with information beyond their reach, and allows the vehicle to make more informed and coordinated decisions.

Whereas LOS sensors cannot indicate vehicle or driver intent, C-V2X conveys intent by sharing sensor data – resulting in a higher level of predictability in traffic situations such as lane changes, variable speeds, or road hazards.

Day one use cases include safety features such as emergency electronic brake light and forward collision warning, ‘do not pass’ warning, blind spot and lane change warning, vulnerable road user, road works warning, and intersection movement assistance.

Tech Focus: The Electric Vehicle Race to Market

Friday, October 29th, 2021

Three rapidly advancing technologies are driving this collective race towards zero-emission e-mobility: wide-bandgap (WBG) devices, more power-dense batteries, and faster charging capabilities.

In this guest commentary, Hwee Yng Yeo from Keysight Technologies shares her insights into the great EV race.

Since its inception on a paper napkin more than a decade ago, Formula E has evolved rapidly as a motorsport with a mission.

Entertainment aside, this electric streetcar racing’s founding mission is to showcase sustainable mobility to the world, and it has done pretty well.

It’s the only motorsport to have ISO 20121 certification for net zero carbon footprint since its first race in Shanghai in 2014.

Getting the Formula E car into pole-position entails a lot of hardware and software technology to extract maximum efficiency from the electric vehicle’s (EV) powertrain and battery.

For the key automotive OEMs, it’s not just about getting their car across the checkered flag first.

With billions of R&D dollars poured into developing better EVs, the goal of participating automakers goes beyond the championship trophy.

Learnings from these high-intensity races are applied to improve electromobility technologies back in the R&D labs.

Three rapidly advancing technologies are driving this collective race towards zero-emission e-mobility:

  1. wide-bandgap (WBG) devices
  2. more power-dense batteries
  3. faster charging capabilities

Efficient power conversion with WBG devices

A lot of power conversion takes place in the EV.

A DC-DC converter for example, steps down the power from the high-voltage EV battery to 12 V, with further conversions to run onboard systems like lighting, radio, and air-conditioning (see the diagram above).

The author of this article is Hwee Yng Yeo, the industry solutions manager for Automotive and Energy at Keysight Technologies.

WBG devices such as Silicon carbide (SiC) and Gallium nitride (GaN) semiconductors are used in transistors to facilitate this power conversion throughout the vehicle.

GaN applications are an emerging technology area, and developers find it hard to validate their design for these high-performance power converters.

Increased frequency and higher power affect the reliability of measurements needed to characterise the device’s performance.

It can be hard to distinguish whether the measured signal is the device’s characteristic or caused by the measurement setup.

I asked Jitender the key to Signify’s competitive advantage in helping its customers embrace IoT.

Three simple words: “Lighting is ubiquitous,” says Jitender, head honcho for Singapore and Emerging Markets at Signify.

Lighting is ubiquitous,” says Jitender Khurana, head honcho for Singapore and Emerging Markets at Signify.

But how does that give Signify a leg up in helping businesses embrace IoT more quickly and easily?

Well, the most tedious aspect of rolling out an IoT implementation is typically the deployment of IoT sensors and the network connecting these sensors back to the IoT platform.

Laying the network for both power supply and data tends to be both costly and time-consuming.

For Signify – that network is simply the lighting network that forms the basic infrastructure of any building or facility.

As far as the world leader in lighting is concerned, “Where there’s light(ing), there can be an IoT sensor integrated into the luminaire”.
