the importance of battery testing

[CONTENU PARTENAIRE] American company Keysight Technologies manufactures test and measurement equipment and software. This multinational has more than 80 years of experience in the test and measurement industry, and 30 years in the automotive field. Below, Thierry Locquette, President of Keysight Technologies France, tells us about a big challenge for us in the coming years: battery testing for electric vehicles.

Can you introduce Keysight Technologies?

Keysight provides design, emulation and test solutions that enable engineers to design new technologies in communications and industrial ecosystems, aerospace and defense, automotive, energy, semiconductors and general electronics.

With over 80 years of experience, Keysight is the world’s leading test and measurement provider. We have more than 32,000 customers in more than 100 countries, and we generated $5.4 billion in revenue for our fiscal year 2022.

Listed on the New York Stock Exchange since 2014, Keysight Technologies is a branch of Agilent Technologies, itself created in 1999 as a spin-off from HP.

Do you see a big change in the automotive industry?

Yes, many: we can mention changes related to national or European sovereignty, with reindustrialization, changes related to global warming… But there is one industry that will change completely in the coming years, that is the car! After more than a century of thermal engine cars, the electric age is coming. This change has been accelerating since the European Union declared the end of combustion engines for 2035. Previously, electric vehicles represented about 1% of sales. They are now between 15% and 20%, and the big car manufacturers are drawing up plans to reach 100% sales in due time.

This change indicates a very strong change in the market, starting with builders : opening new factories or converting existing factories, recruitment, training, establishing new partnerships… One of the biggest challenges is in the field of batteries.

Nowadays, most batteries are from Chinese. gold, by 2030 or 2035, about 90% will have to be European. Hence the creation of these gigafactories (battery factories in Europe), at the rate of two or three per European country.

In France, they are located in the north, with research centers in Grenoble and Bordeaux. In addition to their number, our batteries have to stand for their quality: cheaper, greener, more secure… They will also have to make it possible to cover more than 400 kilometers, load in less than half an hour and avoid the supply of metals from abroad. The question of their recycling must also be resolved and effectively quickly.

To this challenge is added that of chargers: currently, 10 times more chargers must be deployed in Europe, and thousands of interoperable and fast models must be produced every day. Without forgetting the electricity network that has to adapt to thousands of simultaneous demands across Europe…

How do you support all this change?

Keysight Technologies is a partner of choice. We empower designers and manufacturers in the automotive industry with the latest design innovations and testing solutions to help create high-quality, high-performance products, while mitigating safety risks to whole life cycle. automotive life. This includes battery test systems for cell, module and pack level testing, charging functionality and interoperability testing, and renewable energy testing.

Our expertise allows us to test the charger with its battery, at all levels, to ensure that everything complies with European standards. These tests of the charging station and the battery (including its cells, modules and packs) are necessary to guarantee maximum safety, and above all:

● Avoid the risk of electric shock, fire or explosion;

● Make sure the charger connectors fit in all vehicles;

● Ensure that the battery can be recharged within a few minutes. That is, benefit from large upstream power, while maintaining safety standards.

Among our customers, we count the Swedish company Scania, one of the world leaders in trucks. German manufacturer BMW also uses our solutions to test electric batteries, their autonomy and ensure their compliance with European standards and their interoperability.

What do you think is your biggest challenge right now?

All test and measurement providers face the same problem: have considerable financial capacity to increase production capacity. Another challenge is to develop new test products to meet the needs of today and tomorrow. Therefore, our equipment must be modular, so as not to become obsolete. In addition, reducing the battery charging time is a big challenge, and it is only possible with a strong investment in R&D.

These technological challenges are also overtaken by energy challenges. In fact, the cost of energy is exploding. Megawatt-hour is multiplied by 10 in a year. Hence the development of new products that offer maximum energy efficiency.

On the other hand, the electrical tests must be accompanied by thermal tests to ensure the operation of the batteries, regardless of the climatic conditions. Keysight has established close relationships with the main climatic chamber manufacturers in Europe to enable us to serve our regular customers in the best possible conditions.

Do you have the last word?

As with every technological revolution, there is a high probability that the electrical test market will consolidate, with players set to lose or gain. To differentiate itself from the competition, it will be necessary to innovate and demonstrate production capacities in strong growth, to meet an enormous and largely unprecedented need.

This innovation will be at the service of our customers, to enable them to develop and test their batteries to meet market expectations: not paying more than a thermal vehicle, not having to recharge the battery every 300 or 400 km , don’t wait too long while loading… The areas of concern are wide, and we are only at the beginning of this change.
