1. Battery status: Whether a new energy vehicle can start after being parked for half a month mainly depends on the condition of its battery. If the battery is fully charged and the vehicle has a battery management system to maintain power, it can usually start smoothly.
2. Vehicle system: In addition to the battery, other systems of the vehicle may also be affected after prolonged parking. But generally speaking, as long as the battery level is sufficient, these systems should be able to work properly and support vehicle startup.
3. External factors: External factors such as the impact of parking environment on vehicles also need to be considered. Under extreme environmental conditions, battery performance may decrease, affecting startup. Meanwhile, if the vehicle's parking position causes the battery to discharge too quickly, it may also result in the battery being depleted and unable to start.
After being parked for half a month, new energy vehicles can usually start when the battery is fully charged, the vehicle system is normal, and external conditions are suitable. But to ensure smooth start-up, it is recommended to regularly check the battery level and avoid prolonged parking in extreme environments or not turning off the vehicle's power.
