Method for calculating filter load estimation, system for cleaning environmental air, and vehicle comprising same

A method for calculating a filter load estimation in a vehicle,

• the vehicle comprising:
• an air cooling system comprising:
• a heat radiator and
• a filter in an airstream when air is flowing through the filter,
• the heat radiator for cooling coolant fluid, the coolant fluid for transporting heat from a battery to the heat radiator;
• a battery temperature sensor and/or a coolant temperature sensor;
• and
• an exterior air temperature sensor,
• wherein the sensors are operably in communication with a computer memory of the vehicle;
• the method comprising:
• obtaining, from the computer memory of the vehicle:
• charging status data representing a charging condition of the battery;
• and
• charging power data representing a charging power being used for charging the battery;
• obtaining an exterior air temperature from the exterior air temperature sensor;
• determining from the charging status data that the charging condition of the battery is that the battery is being charged;
• and
• providing, with a fan, air flow through the heat radiator and the filter,
• wherein the method further comprises
• obtaining a battery charging parameter and
• calculating the filter load estimation based on the exterior air temperature, the charging power data and the battery charging parameter.
