The widespread worry about the quantities of hazardous gases released by internal combustion engines (especially in metropolitan areas) has reignited interest in electric traction. The usage of battery-powered vehicles, especially industrial trucks and commercial road vehicles of various sorts has advanced significantly. Forklift trucks, mining, airport tractors, aviation service vehicles, electric automobiles, and, more recently, robots and guided vehicles are just a few of the industries where these batteries are used.
Traction batteries are superior to SLI batteries in terms of quality. They have a stable output voltage, a large volumetric capacity, superior vibration resistance, and a long service life. They can tolerate daily deep discharges followed by deep recharges. Traction batteries have a voltage range of 12 V to 240 V and cycle life of 1000-1500 cycles.
A variety of sophisticated batteries are being developed for usage in electric vehicles such as Zinc-nickel oxide batteries (75 Zinc-nickel oxide batteries (75 Wh/kg) and zinc-chlorine hydrate batteries (80 Wh/kg) are both room temperature batteries being researched for use in electric cars and High-temperature batteries include sodium-sulfur batteries (120 Wh/kg) and lithium-iron sulphide batteries (100 Wh/kg).
