The energy to weight ratio must be maintained for the performance and safety of an EV. A battery with a high energy density has a longer battery run when compared to its size. But if the energy density is too high, it could present a safety issue due to the presence of more active material packed into a cell.
The charging process for battery electric vehicles takes a bit longer, unlike conventional internal combustion engines. Using a slower charger could take 5 – 10 h to fully charge the battery, while a fast charger might take around 15 – 45 min, which is slower than ICE''s .

There are three basic types of battery cells used in electric vehicles: cylindrical cells, prismatic cells, and pouch cells. There are also coin cells, which are used in research and development for testing purposes, but never actually used in electric vehicles. The number of cells in an EV varies widely based on the cell format.
There are three types of EV battery cells for electric vehicles: cylindrical, prismatic, and pouch. All of these batteries are lithium-ion based with some type of casing. Each type of battery has a specific chemical composition, size, capacity, and lifespan that make them more or less desirable for EVs.
Pouch batteries are a controversial choice. Some companies like General Motors believe pouch cells are the key to the electric vehicle future. While other companies, like Tesla, are quoted saying they will never use pouch cells. The EV market is quickly growing, and manufacturers are searching for the best battery for their vehicles.
As the battery gets larger, the total power is split between a higher number of cells, and each cell needs to deliver less power. Hybrid cars, for example, have a smaller battery and often require power cells. Power cells allow keeping the battery small while meeting power needs. Power cells are not limited to smaller batteries.
For our electric vehicle battery design we are going to start from 4 core input parameters: A battery consists of one or more electrochemical cells (battery cells) which are converting chemical energy into electrical energy (during discharging) and electrical energy into chemical energy (during charging).
Because of the cylindrical shape, combining these EV battery cells into a battery pack leaves gaps between cells. The gaps prevent the density from reaching the strength of a pouch or a prismatic battery if those were combined. Cylindrical batteries also can be heavy because of their steel or aluminum shells.
