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.

In this paper, the battery energy storage technology is applied to the traditional EV (electric vehicle) charging piles to build a new EV charging pile with integrated charging, discharging, and storage; Multisim software is used to build an EV charging model in order to simulate the charge control guidance module.
The traditional charging pile management system usually only focuses on the basic charging function, which has problems such as single system function, poor user experience, and inconvenient management.
The simulation results of this paper show that: (1) Enough output power can be provided to meet the design and use requirements of the energy-storage charging pile; (2) the control guidance circuit can meet the requirements of the charging pile; (3) during the switching process of charging pile connection state, the voltage state changes smoothly.
Given that traditional natural convection or air-cooling techniques cannot meet the heat dissipation requirements of high-current charging cables, the method of directly immersing the cable core in insulating heat-conductive oil for active liquid cooling becomes the inevitable choice.
However, for high-power fast charging and superfast charging, active liquid cooling that combines pumps and coolants (such as water and dimethyl silicone oil) needs to be used . In addition, the phase-change heat transfer technology of coolants also should be introduced as the charging power increases in the future [12, 13].
The charge power of household charging stations using the alternating current (AC) is commonly within 10 kW, referred to as a trickle charge. A system that charges vehicles with direct current (DC) of 50–60 kW is called a fast-charging system, and those charging vehicles with the power higher than 150 kW are termed superfast charging systems.
Chinese automakers and battery giants, including BYD, CATL, and NIO, are teaming up to form an “all-star” lineup aimed at developing all solid-state EV batteries.
One of the top Chinese solid state battery manufacturers is CATL (Contemporary Amperex Technology Co., Limited). They have developed a lithium iron phosphate solid-state battery with high energy density and improved safety features. Their technology focuses on enhancing performance and extending battery life.
In a move that could revolutionize the EV market, China's leading auto and battery manufacturers are forming an alliance to commercialize all solid-state batteries. According to Nikkei Asia, the China All-Solid-State Battery Collaborative Innovation Platform, or CASIP, was formed last month.
Solid-state batteries are sensitive to moisture, so their manufacturers need special equipment to keep humidity away from production lines. While government initiatives should accelerate solid-state battery development, Chinese companies aren't waiting. Battery makers have already started formulating plans for the next-gen technology.
China already leads the battery industry and is now looking to establish itself as a juggernaut of solid-state batteries, creating a massive consortium of major battery manufacturers, researchers, and government officials.
Chen Qingtai, head of China EV100, argued that solid-state EV batteries can shift the industry's power balance. Working together will ensure China becomes an “automotive powerhouse.” Although many others, including Toyota, have promised to bring solid-state EV battery tech to market for years, there's still little show.

Such a structure equipped with solar panels is simply known as a solar-powered greenhouse. Solar-powered greenhouses harness the sun's power to create an ideal environment for plant growth. There are different types of solar greenhouses, and each comes with its own strengths and weaknesses. Unlike conventional greenhouses that rely on external energy sources, these innovative structures harness and store the sun's energy. Photovoltaic, or solar, greenhouses are built by installing photovoltaic panels on the roof, which produce electricity. It is a rapidly expanding phenomenon that makes it possible to improve the energy yields of a farm and at the same time reduce water consumption.
