Rapid, Mobile, EV Battery State of Health Tests at the Cellular Level
EV BATTERY SOH
High-voltage, EV battery State of Health, or SoH, is defined as the remaining capacity of the EV battery to store energy. The SoH is measured as a percentage out of 100%. An 80% SoH is 80% of battery capacity remaining. However, this is not 80% of EV battery capacity remaining as the OEM’s, (original equipment manufacturer), mark 70% as End of Life, or EOL. We’ve included the graphic below to help you understand what the SoH numbers may actually mean to used EV battery health. Keep in mind these are generalizations and that actual percentages and their values may vary widely based on battery chemistry, vehicle condition, driving habits, and battery management.
70%
POOR
End of Life for an EV Battery as defined by the manufacturer’s warranty. EV loss of function and range may be gradual.
75%
FAIR
Nearing EOL as an EV Battery. Usually an older or poorly maintained battery. Usable life for short distances.
85%
GOOD
Near 50% usable capacity although battery degradation is not linear. Common for high mileage, 3-5 year-old EVs
95%
EXCELLENT
Well managed EV battery. Not uncommon for 3 year-old EVs, under 50,000 miles, with good battery management.
100%
NEW
Your brand new EV comes off the factory floor with 100% battery storage capacity. 100% Battery SoH.
MOBILE TECHNICIANS
EV VERIFIED™ mobile technicians are equipped with satellite connectivity, diagnostic tools, full-color printers, and EV Checks to test private party EVs, dealer inventory, and commercial fleets. Testing procedures vary by OEM, year, make, and model. The battery is never physically touched, but occasionally, plastic trim panels are removed to access diagnostic ports, ethernet inputs, and CAN bus connections.
DATA ACCESS
Technicians use DOIP, data over internet protocol, and proprietary software to access the vehicle’s on-board computer. The vehicle feeds the data to the analytic program which identifies the make and model by VIN, tests systems, and collects temperature, current, and battery cell voltage data. A VIN-Specific, SoH report is forwarded in under twenty minutes.
SOH REPORTS
A VIN-Specific report is emailed to the customer detailing the MAKE, MODEL, and MILEAGE of the EV along with the State of Health, SoH, at the time of the test, new vs. projected range, benchmarking vs. identical models, and battery cell health by group.
SOH PREVIEW
A PREVIEW of the test, highlights the SoH score for marketing purposes. These previews are emailed to the customer and, in some cases, affixed to the window of the EV VERIFIED™ EV. EVs with high SoH scores are often featured onsite and online with the EV-Check promoting its strong battery SoH.
AVILOO FLASH TEST RESULTS EXPLAINED
The AVILOO FLASH Test
The AVILOO Flash Test results are delivered in two files with three sections. THE PREVIEW CERTIFICATE, the REPORT CERTIFICATE Page One, and the REPORT CERTIFICATE Page Two. The reports are emailed to the customer and linked online via QR Code.
The AVILOO PREVIEW
The AVILOO Flash Test PREVIEW identifies the make, model and VIN of the tested vehicle and the test date. The SoH number is clearly visible and linked online via QR Code. Energy and range numbers at current SoH vs. New are displayed and AVILOO identifies their evaluation of battery condition as POOR, FAIR, GOOD, or EXCELLENT as seen below.
The AVILOO REPORT PAGE ONE
Page One of the AVILOO Flash Test results are broken into four panels as detailed below.
The AVILOO REPORT PAGE TWO
Page Two of the AVILOO Flash Test results are broken into seven panels as detailed below.

EV BATTERY HEALTH TEST FAQs
Answers to frequently asked questions about EV battery tests.
Q1. What Makes and Models does EV VERIFIED test?
A list of EV VERIFIED, Inc. EVs tested is listed on the MODELS page and includes the most common makes and models of battery electric vehicles, BEVs, and most hybrid/plugin hybrid electric vehicles, HEVs, PHEVs.,
Q2. How long is a high-voltage EV battery test?
A Premium Test is an in-depth, dynamic diagnostic test that requires the vehicle to be charged to 100% and then driven down to 10% charge (usually within 7 days) to measure live degradation and cell performance. The benefit of a Premium Test is better forecasting of future range and degradation based on live degradation and cell performance data collected over several days.
Q3. What does the battery test measure?
Commercial-grade, EV battery State of Health, SoH, tests measure vehicle communications, sensors, temperature, current, battery management system, the battery pack and battery cell voltages.
Q4. What is EV battery State of Health, SoH?
High-voltage EV battery State of Health, SoH, is the percentage of remaining battery storage capacity from the 100% it had when it left the factory. This measurement helps to determine remaining range and current value of a used EV. A bad EV battery replacement could cost as much or more than the used EVs market value.
Q5. What State of Charge, SoC, should my EV be at for the test?
High-voltage EV batteries receiving a rapid test should be at 40-80% State of Charge, SoC. Premium Tests require the electric vehicle to be fully charged to 100% before the test commences.
