Battery & Energy Storage Engineering Certification

The Battery & Energy Storage Engineering Certification is a free advanced-level, 25-minute skill test from Science of Apps. It tests battery and energy storage engineering — electrochemical cells, anodes, cathodes, electrolytes and separators, lithium-ion chemistries including NMC, LFP and NCA, cell formats from cylindrical to pouch and prismatic, energy versus power density, C-rate, state of charge and state of health, open-circuit voltage, internal resistance and equivalent circuit models, coulombic efficiency and round-trip efficiency, calendar and cycle ageing, SEI growth, lithium plating and capacity fade, thermal management and thermal runaway, battery management systems, balancing and safety protection, pack design, module architecture and busbars, second-life and recycling, grid storage applications from frequency response to arbitrage, sizing by power and duration, levelised cost of storage, NFPA 855 and UL 9540A safety practice, long-duration and alternative technologies including sodium-ion, flow and thermal storage — written to DOE, IEA, NREL, NFPA and UL sources for 2026 and 2027. Score 70% or more on its 25 questions to earn a verifiable Battery & Energy Storage Engineering certificate (SOA-BESE). Every question is based on published standards and research — including Vehicle Technologies Office: batteries and electric drive research (US Department of Energy), Batteries and Secure Energy Transitions (International Energy Agency), Energy storage research and cost projections (National Renewable Energy Laboratory) — and each answer is explained with its source.

Science of Apps offers a free Battery & Energy Storage Engineering Certification, written for 2026 and 2027. It tests electrochemistry and cells, performance and degradation, thermal, BMS and pack design, applications, safety and economics and manufacturing and supply chain with 25 original scenario questions in all, each naming its published source; you get an instant score and a verifiable certificate with a credential ID you can add to LinkedIn.

Read the five skill areas on this page, then take the 25-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a Battery & Energy Storage Engineering certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: Vehicle Technologies Office: batteries and electric drive research (US Department of Energy); Batteries and Secure Energy Transitions (International Energy Agency); Energy storage research and cost projections (National Renewable Energy Laboratory); UL 9540A test method for thermal runaway fire propagation in battery energy storage (UL Solutions); Energy storage: grid integration, safety and research (US Department of Energy Office of Electricity); NFPA 855: Standard for the Installation of Stationary Energy Storage Systems (National Fire Protection Association). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Five skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Electrochemistry and Cells (Cell components, Chemistries and Formats and metrics); Performance and Degradation (Operating parameters, Models and Ageing); Thermal, BMS and Pack Design (Thermal management, BMS and Pack integration); Applications, Safety and Economics (Grid and mobility, Codes and safety and Economics and alternatives); Manufacturing and Supply Chain (Cell manufacturing, Testing and Materials and recycling). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Battery or energy storage engineer, EV or consumer electronics hardware engineer, Grid storage developer or asset manager, Materials or chemical engineering student and Clean energy analyst or investor. It suits students at leading universities, career switchers and experienced professionals who want quick, verifiable proof of Battery & Energy Storage Engineering knowledge in 2026 and 2027.

Engineering cohorts at IITs, KAIST, NTU Taiwan, TUM, Tsinghua and Georgia Tech are being pulled into chips, energy and space. Passing earns a founder-signed Science of Apps certificate with a credential ID and QR code that recruiters can verify.

Energy density is how much energy a cell stores per unit mass or volume, which sets range or duration; power density is how fast that energy can be delivered, which sets acceleration or discharge rate.

Lithium iron phosphate uses no nickel or cobalt, offers long cycle life and a higher thermal runaway onset temperature, and costs less per kWh, which suits stationary storage and standard-range vehicles.

Yes. The test is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.

25 questions — 5 from each of 5 skill areas — with a 25-minute limit. You need 70% (18 of 25) to pass and 90% for distinction.

We rate it Advanced: assumes years in the role or deep specialist knowledge. It has 25 scenario questions — 5 from each of 5 skill areas — and a 25-minute limit. You need 70% (18 of 25) to pass and 90% for distinction.

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
