EPA label examples showing MPG and MPGe for gasoline, hybrid, and fully electric vehicles. (Credit: EPA) What Does MPGe Really Mean? Like miles per gallon (MPG), the higher the MPGe the better.
A car that uses 33.7 kilowatt-hours (kWh) of electricity to travel 100 miles rates 100 MPGe. When the EPA devised MPGe in the early 2000s, the government agency calculated that 33.7 kWh of electricity was comparable to a gallon of gasoline fuel in terms of its energy content.
Most people do not need the 200-400 miles of range most EVs have on a daily basis. So, if saving money while driving around town is your biggest priority—perhaps you use a gas-powered or hybrid car for longer trips—go with the highest MPGe you can find. The EPA label includes estimated gas savings for each vehicle.
The average cost of electricity for the last several years has been about $0.12 (vertical line). The average (dashed line) crosses the vertical line at about $0.035/mile. Compare to this graph that shows driving cost for gasoline cars:
MPGe is a simple, but important measurement that prospective buyers of electric vehicles and plug-in hybrids need to understand. When shopping for any type of electric car, you'll notice a slight change on the windshield label: A little "e" has found its way next to the age-old "MPG" fuel rating.
When it comes to MPGe for electric vehicles and mpg for gasoline-powered cars, they might seem very similar. But there's a big difference between the two. The formula for MPGe can be calculated as follows: 33.7 kWh of electricity = one gallon of gas. Some cars can get 100 MPGe.
Although the regulations allow some optional approaches, the most common approach is to use a factor of 0.7 to adjust all the test parameters, including range. For example: An EV achieves 200 miles on the highway laboratory test. Real-world highway driving range → 200 x 0.7 = 140 miles to account for aggressive driving and HVAC use.
According to my calculations, this would give us ≈3. I also thought of it like this: Drawing this much current at 9 V would require around 5 milliohms according to my calculations.
Batteries convert chemical energy into electrical energy by means of a chemical reaction. A standard D-size carbon-zinc battery has an Ah (amp-hour) capacity of approximately 4.5 to 8 Ah (4500-8000 mAh). This means that a D battery could supply 6.25 amps of current for about one hour, more or less.
Based on these results, current draw and temperature differences have an influence over the effective battery energy capacity of common AAA batteries. Larger discharge currents consistently led to a lower measurable, starting voltage and faster overall drain. The batteries also showed a difference in the overall total energy output.
Power capacity is how much energy is stored in the battery. This power is often expressed in Watt-hours (the symbol Wh). A Watt-hour is the voltage (V) that the battery provides multiplied by how much current (Amps) the battery can provide for some amount of time (generally in hours). Voltage * Amps * hours = Wh.
The higher the power, the quicker the rate at which a battery can do work—this relationship shows how voltage and current are both important for working out what a battery is suitable for. Capacity = the power of the battery as a function of time, which is used to describe the length of time a battery will be able to power a device.
Energy in a battery is expressed in Watt-hours (the symbol Wh), which is the voltage (V) that the battery provides multiplied by how much current (Amps) it can provide for a given amount of time (typically in hours). What are the different types of batteries?
Energy or Nominal Energy (Wh (for a specific C-rate)) – The “energy capacity” of the battery, the total Watt-hours available when the battery is discharged at a certain discharge current (specified as a C-rate) from 100 percent state-of-charge to the cut-off voltage.
In this study, battery abnormal decline is defined as non-linear capacity decline batteries (under a statistical probability perspective) from a large sample of batteries.
With an increasing number of lithium-ion battery (LIB) energy storage station being built globally, safety accidents occur frequently. Diagnosing faults accurately and quickly can effectively avoid safe accidents. However, few studies have provided a detailed summary of lithium-ion battery energy storage station fault diagnosis methods.
Anomaly diagnosis of lithium-ion battery based on the local outlier factor. The authors in ref. introduce a diagnostic method based on voltage and temperature data during charging and discharging, utilising real operational data. Here, cells exhibiting median voltage and temperature values are deemed normal.
Statistical analysis-based methods diagnose battery faults by identifying abnormal characteristics in observation data and comparing these with predefined thresholds. These approaches include techniques such as Shannon entropy, principal component analysis (PCA), and independent principal component analysis (ICA).
Therefore, effective abnormality detection, timely fault diagnosis, and maintenance of LIBs are key to ensuring safe, efficient, and long-life system operation [14, 15]. Battery fault diagnosis can assess battery state of health based on measurable external characteristics, such as voltage and current [16, 17].
Early and precise prediction of voltage anomalies during the operation of energy storage stations is crucial to prevent the occurrence of voltage-related faults, as these anomalies often indicate the possibility of more serious issues.
Accurately detecting voltage faults is essential for ensuring the safe and stable operation of energy storage power station systems. To swiftly identify operational faults in energy storage batteries, this study introduces a voltage anomaly prediction method based on a Bayesian optimized (BO)-Informer neural network.

That's especially true for hard-to-find new electric cars. Of course, if you absolutely need a new vehicle because your current car has reached the end of its road, was totaled in a collision or was stolen, then, by all means, buy a new car. Just be aware that it might be more difficult than it was before the pandemic.
We've all heard of electric vehicles, but have you heard of an EV that doesn't need a battery? London-based nanoFlowcell Holdings plc (NFC) has set up a US subsidiary in New York called nanoFlowcell USA LLC, which aims to sell the Quantino twentyfive, an electric sports car without a battery.
Most EV buyers won't have to pay if there's a problem with their EV's battery pack because federal law requires automakers to provide eight years or 100,000 miles of battery coverage. If you do need a new battery pack that's not covered by the car's warranty, you can expect a bill in the thousands or even tens of thousands of dollars.
“Almost all of the [electric car] batteries we've ever made are still in carsAnd we've been selling electric cars for 12 yearsIt's the complete opposite of what people feared when we first launched EVs – that the batteries would only last a short time”
When inventory on certain popular models is low, then dealers don't have any incentive to give you a good deal, and some are even charging more than sticker price for new vehicles. That's especially true for hard-to-find new electric cars.
Battery electric vehicles (BEVs, or simply EVs) are what most people think of when the term "electric car" comes up. These vehicles do not have conventional engines at all — fossil fuels are simply not involved in their operation. Instead, EVs rely on electricity from large battery packs, which must be recharged by plugging the car in.
Energy density refers to how much energy can be stored per unit volume (Wh/L) or weight (Wh/kg) in a lithium-ion battery, making it a key factor in improving battery performance for mobile devices.

Future Potential: Inexpensive and highly scalable for renewable energy storage Zinc-air batteries are emerging as a promising alternative in the energy storage field due to their high energy density, cost-effectiveness, and environmental benefits. They have an energy density of up to 400 Wh/kg, rivaling lithium-ion batteries.
Next-generation batteries are also safer (less likely to combust, for example), try to avoid using critical materials that require imports, rare minerals, or digging into the earth, and can store more energy (letting you drive further in your electric vehicle before finding a charging station, for example).
The U.S. Department of Energy (DOE) and its Advanced Materials and Manufacturing Technologies Office (AMMTO) is helping the U.S. domestic manufacturing supply chain grow to fulfill the increased demand for next-generation batteries.
These next-generation batteries may also use different materials that purposely reduce or eliminate the use of critical materials, such as lithium, to achieve those gains. The components of most (Li-ion or sodium-ion [Na-ion]) batteries you use regularly include: A current collector, which stores the energy.
Plus, some prototypes demonstrate energy densities up to 500 Wh/kg, a notable improvement over the 250-300 Wh/kg range typical for lithium-ion batteries.
