August 1, 2023 - Vista, California - Axiom Test Equipment, an electronic test equipment rental and sales company has published a new blog post entitled "Get a Charge Out of Testing EV Batteries" that covers the different units that meet the needs of large batteries used in modern EVs, specifically when it comes to testing the battery's charge capacity and operating lifetime. It's important to note that having access to suitable test equipment has played a major role in the development of high-density DC electric power packs capable of adding many miles to the ranges of modern EVs and HeVs.

Battery packs for EVs are energy storage systems comprised of many small cells. Each section of the battery pack contributes electric power to the whole and all the sections are designed for high power and high reliability. EV battery packs do degrade in performance over time, eventually losing the capability to hold the original amount of energy during a recharge cycle. Testing an EV battery for charge capacity is one way to understand its capabilities at that time and to project its operating lifetime to reach a given charge capacity. EV battery capacity testing can be performed according to a manufacturer's guidelines or per regulations set by technical organizations, such as the Institute of Electrical and Electronics Engineers (IEEE).

Test equipment for EV batteries must meet or exceed the voltage, current, and power levels absorbed and dissipated by a battery during its charge and discharge cycles, respectively. Learn more about the most important equipment you will need when testing batteries for EVs by reading the full blog post on Axiom's website:  https://www.axiomtest.com/blog/Get-a-Charge-out-of-Testing-EV-Batteries/

Get a Charge Out of Testing EV Batteries

Roads are slowly filling with electric vehicles (EVs) and hybrid electric vehicles (HEVs), helping to clean the Earth's “carbon footprint” by minimizing emissions from internal combustion engines. The growing number of affordable EVs and HEVs is coming in large part because of the availability of reliable rechargeable battery packs, such as lithium-ion (Li-ion) batteries capable of storing enough power to support practical driving ranges under electric power for EVs and HEVs. Manufacturers of battery packs for EVs and HEVs have worked closely with designers and manufacturers of EVs and HEVs to achieve efficient rechargeable fuel cells with generous energy capacity and long operating lifetimes. Having access to suitable test equipment has played a major role in the development of high-density DC electric power packs capable of adding many miles to the ranges of modern EVs and HeVs.

For characterizing any kind of rechargeable vehicle battery or energy storage device and analyzing the charging stations and electronic devices used to recharge EV/HeV batteries, the test equipment must be capable of behaving like a power supply during a charging cycle and an electronic load during a discharge cycle. Battery packs for EVs are energy storage systems comprised of many small cells. Each section of the battery pack contributes electric power to the whole and all the sections are designed for high power and high reliability. EV battery packs are quite large, typically weighing about 1200 lbs. for a Tesla EV. They are designed for long lifetimes, typically 10 years and 100,000 miles, although they may be usable for 20 years or longer.

EV battery packs do degrade in performance over time, eventually losing the capability to hold the original amount of energy during a recharge cycle. Testing an EV battery for charge capacity is one way to understand its capabilities at that time and to project its operating lifetime to reach a given charge capacity, such as 80% which will also mean a less-distant driving range for a “fully” charged EV battery.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
