When selecting a PHEV, you must prioritize the All-Electric Range (AER), typically ranging from 50km to 120km, to ensure it meets the buyer's daily commuting needs. Evaluate the Battery Chemistry, where Lithium Iron Phosphate (LFP) offers higher safety and cycle life, while Nickel Manganese Cobalt (NMC) provides higher energy density. Additionally, confirm the Charging Standards (e.g., Type 2, CCS2, or GB/T) to ensure compatibility with the destination country's infrastructure, and verify the Powertrain Integration for seamless switching between the internal combustion engine and the electric motor.
