Method for charging electric bus

Abstract

The invention provides a method for charging an electric bus, and belongs to the field of methods for charging electric buses. In a power utilization low-ebb load period, a battery management system of an electric bus is set, 110A current charging is performed on an electric bus battery, power supply of the battery management system is automatically cut off till the electric bus battery is fully charged, when the time electric bus makes a round trip between a starting station and a terminal station is in a power utilization peak load period, time for parking and rest is used to set the battery management system of the electric bus, 240A current charging is performed on the electric bus, the charging time is 5 min to 10 min, when the supplemented electric quantity is 5% to 15% of the total electric quantity of the electric bus battery, power supply of the battery management system is automatically cut off, power utilization cost is low, bus dispatching efficiency does not needed to be ensured by increasing electric buses, and the life of the battery can be prolonged.

Description

technical field [0001] The invention provides an electric bus charging method, which belongs to the field of electric bus charging methods. Background technique [0002] Existing buses are often charged regardless of time period when charging, and in order to ensure the efficiency of departure, generally use a large current, that is, a current of 240A, to fully charge the battery of the electric bus at one time, and do not charge between departures , so that the electric bus runs back and forth between the starting station and the terminal station until the power is insufficient or reaches its threshold, that is, the remaining power is not enough to run from the starting station to the terminal station, and then perform a one-time charge. Under the current situation, the normal departure efficiency is often ensured by increasing the number of electric buses. This method can not reasonably control the electricity cost, but also needs to increase the cost of car purchase, whic...

[0002] Existing buses are often charged regardless of time period when charging, and in order to ensure the efficiency of departure, generally use a large current, that is, a current of 240A, to fully charge the battery of the electric bus at one time, and do not charge between departures , so that the electric bus runs back and forth between the starting station and the terminal station until the power is insufficient or reaches its threshold, that is, the remaining power is not enough to run from the starting station to the terminal station, and then perform a one-time charge. Under the current situation, the normal departure efficiency is often ensured by increasing the number of electric buses. This method can not reasonably control the electricity cost, but also needs to increase the cost of car purchase, which is a waste of resources and greatly affects the life of the electric bus battery.
