What is an Electric Car Battery
An electric car battery (also known as an electric vehicle (EV) battery or electric car battery) is a rechargeable battery used to provide power to the electric motor of a battery electric vehicle (BEV) or a hybrid electric vehicle (HEV) (According to Wikipedia)
Electric car batteries consist of multiple modules connected in series
Electric car batteries are composed of a collection of battery cells assembled into modules, consisting of a positive electrode (cathode) and a negative electrode (anode) along with an electrolyte solution. Each complete EV battery pack for an electric car can consist of up to dozens of modules.
Lithium-ion (Li-ion) Batteries for Electric Cars
In the early 1990s, lithium-ion batteries were commercially introduced with a high energy storage capacity. Unlike most battery types, they do not experience significant discharge when not in use due to their self-discharge feature.
How Lithium-ion Batteries Work
Scientific focus on innovation has led experts to believe that lithium-ion batteries have almost evolved into an ideal rechargeable battery type, making them the best choice for providing power to future electric cars.
Although the production cost of these batteries is high, they are still the most widely used in electric vehicles. This can be considered their biggest disadvantage. However, comprehensive research on battery technology has helped reduce production costs.
Li-Ion batteries weigh only 1/3 compared to lead-acid batteries, have a lifespan three times longer, and are three times more powerful. Li-Ion batteries also have the advantage of a higher energy density, exceeding 140 Wh/kg.

Lithium-ion batteries are also much safer than many alternative types, and battery manufacturers must ensure the implementation of safety measures to protect consumers in case of unlikely battery malfunctions. For instance, electric vehicles are equipped with charging protection measures to safeguard the battery during repeated fast charging over a short period.
Alongside the development of Lithium-ion batteries for electric vehicles, various fast-charging methods have emerged. One notable example is the technology of charging the battery of an electric car while it is in motion, presenting technological challenges for our future. Readers can explore more about this in the article Technology Challenge: Charging Electric Car Batteries While Driving.
Wireless Charging Technology Solutions
The first charging technology involves installing magnetic coils beneath the asphalt layer to enable wireless battery charging, similar to mobile phones. The second technology is to run electric charging cables beneath the asphalt layer and install charging sockets on the ground.
These "electric road" systems could accelerate the ongoing revolution in the automotive industry, allowing electric vehicles to run for longer without stopping for battery charging. Moreover, it eliminates the need for heavy and material-intensive battery packs.
The concept of this charging technology also demonstrates "excellent energy efficiency, as the continuously available charging source will not hinder the operation of trucks, significantly reducing the necessary size for long-range heavy-duty truck batteries" and helping decrease the demand for charging stations.
However, technological barriers still need to be overcome. The development and widespread adoption of this solution are challenging due to the limited power and high cost of wireless charging technology, causing congestion at charging stations and posing issues for two-wheeled vehicles.
As wireless charging technology has not yet been robustly and optimally developed for users, we still have to resort to using various portable chargers.
