What is an EV Battery Pack?
An EV battery pack is a rechargeable energy storage system used in electric vehicles to supply power to the motor. It consists of multiple battery cells combined into modules and managed through advanced electronics.
Battery Management System (BMS)
Thermal Management Technology
The battery pack stores electrical energy and delivers it efficiently to power the vehicle. Modern EV battery packs use lithium-ion technology because of high performance and low maintenance requirements.
How Does an EV Battery Pack Work?
The working process is simple:
The battery stores electricity using lithium-ion cells.
Chemical energy remains stored until needed.
Stored energy converts into electricity and powers the motor.
Step 4: Regenerative Braking
Some EVs recover energy while braking and recharge the battery partially.
Battery efficiency depends heavily on charging habits, temperature, and driving patterns.
