Operating characteristics of electric vehicles
Battery electric vehicle (BEV) refers to a vehicle that is powered by an on-board power source and driven by a motor to drive wheels, and meets the requirements of road traffic and safety regulations.
Working principle: battery-current-power regulator-electric motor-power transmission system-driving the car (Road).
(1) Buses. Buses are used to meet the needs of public transportation. They are driven and maintained by full-time drivers. They are invested and operated by city bus companies or enterprises. They have fixed driving routes. Large parking lots are generally built at the first and last stations, and they are closed at night. The negative impact caused by the outage of buses is relatively large. It is required that a single charge should meet at least one-way operating mileage. In an emergency, it should be able to achieve rapid replenishment of electrical energy. Buses can be charged during the outage period.
(2) Special park vehicles. Special park vehicles refer to services and sightseeing vehicles used in scenic spots, tourist attractions, urban water source protection areas, etc. Special park vehicles have clear service objectives, relatively concentrated vehicles, frequent use, and it is difficult to meet daily operation requirements on a single charge. Centralized parking lot, special park cars can be charged during the outage period.
(3) Urban sanitation, urban express delivery and collection of vehicles. Urban sanitation and urban express delivery vehicles are vehicles operated to meet the requirements of urban environmental sanitation and mail delivery, such as street sweepers, garbage trucks, road wreckers, washing vehicles, sprinklers, and urban express delivery For collection of vehicles, the running routes of such vehicles are fixed, and they have their own parking lots in their units or enterprises, and there are periods of outage. Statistics show that the average daily operating distance of such vehicles is about 100km per vehicle, and a single charge basically meets the mileage of a single trip, and it can be charged during outages.
(4) Engineering vehicles. Municipal engineering rescue vehicles, construction transport vehicles, etc. are used to meet the needs of municipal construction and emergency maintenance. The affiliated unit or enterprise has a parking lot. The vehicles are used to provide services for specific areas. They are required to be on standby and dispatched at any time. One charge basically meets the round-trip mileage, and it can be charged during outages.
(5) Government official vehicles, corporate commercial vehicles, and other social vehicles. To meet the needs of official and business travel, the affiliated unit or enterprise has a parking lot, which is generally closed at night. The driving route and mileage of the vehicle can generally be estimated, and the route and mileage of the vehicle are changeable in special circumstances. A charge basically meets the round-trip mileage, and it can be charged at night when it is out of service. At the same time, it should provide the necessary fast supplementary power facilities within the corresponding travel range.
(6) Taxi. Taxi operating routes and regions are uncertain and have great randomness. According to statistics, the average daily operating mileage of taxis in provincial capital cities is about 300km per day. The driving range on a single charge is difficult to meet the operation requirements of the day, and the power consumption changes greatly. According to the driving range after a single charge, the necessary charging facilities should be provided within the corresponding travel range. Taxi outages are short and require high charging time.
(7) Private cars. To meet personal travel needs, routes and mileage can generally be estimated in advance, and vehicles are parked in family garages or community parking lots. Basically shut down at night, you can make full use of the trough period to charge.
