What are the main types of EV batteries?
Answer: Lithium-ion (Li-ion) in various chemistries like NMC, LFP, and NCA
Modern EVs primarily use lithium-ion batteries in various chemical compositions.
What is regenerative braking in EVs?
Answer: Converting kinetic energy back to electrical energy during deceleration to recharge the battery
Regenerative braking captures energy that would otherwise be lost as heat.
What is battery thermal management?
Answer: Systems to maintain optimal battery temperature for performance and longevity
Batteries perform best within a specific temperature range.
What is the typical range of a modern EV?
Answer: 200-300+ miles on a full charge depending on battery size and efficiency
Modern EVs offer practical ranges that meet most daily driving needs.
What is State of Charge (SOC)?
Answer: The remaining battery capacity as a percentage of total capacity
SOC indicates how much energy remains in the battery.
What is battery degradation?
Answer: Gradual loss of battery capacity over time and charging cycles
Batteries slowly lose maximum capacity through normal use.
