The lithium iron phosphate battery (LFP) is on the rise, reaching 41 % global market share by capacity for BEVs in 2023. [1]: 85 LFP batteries are heavier but cheaper and more sustainable. At the same time, the first commercial passenger cars are using a sodium-ion battery (Na-ion) completely avoiding the need for critical minerals. [2]
Battery electric cars are becoming more and more attractive with the higher oil prices and the advancement of new battery technology (lithium-ion) that have higher power and energy density (i.e., greater possible acceleration and more range with fewer batteries). [12] Compared to older battery types such as lead-acid batteries.
A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
In a battery electric vehicle (BEV), the state of charge indicates the remaining energy in the battery pack. [4] It is the equivalent of a fuel gauge.. The state of charge can help to reduce electrical car's owners' anxiety when they are waiting in the line or stay at home since it will reflect the progress of charging and let owners know when it will be ready.

Battery capacity: 16.5 kWh lithium-ion battery; Economy: 12 kWh/100 km, also reported to be 200 W·h/mi [20] Range: 135 kilometres (84 miles) on the (NEDC cycle) [1] Top speed: 100 kilometres per hour (62 miles per hour) [2] The lithium-ion battery pack took three hours to charge from 20 to 80 percent of its capacity with a standard 230 V outlet.
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
Peukert's law becomes a key issue in a battery electric vehicle, where batteries rated, for example, at a 20-hour discharge time are used at a much shorter discharge time of about 1 hour. At high load currents the internal resistance of a real battery dissipates significant power, reducing the power (watts) available to the load in addition to ...
