Detection and replacement method for battery of electric bus

Abstract

The invention relates to the technical field of electric bus charging, and particularly relates to a detection and replacement method for a battery of an electric bus. The method comprises the following steps: arranging a charging device in a bus terminal station turnaround, and calculating power consumption X and time T of a bus from a starting point to a terminal point, so as to obtain the upper limit value of the charging capacity q in the unit time of the charging device and the maximum charging capacity R of the battery in the time T; arranging a heat sensitive sensor in a charging station, wherein a lithium battery is adopted as the battery of the bus, and the temperature range of the lithium battery in normal working is 0-60 DEG C; when X is less than or equal to M and the temperature of the battery does not exceed 60 DEG C, replacing a fully charged battery, and if the temperature exceeds 60 DEG C, replacing a standby battery and cooling and then charging the replaced battery; and when X is greater than M, replacing the standby battery, and detecting the electric quantity and performance of the replaced battery by virtue of calculation of a computer and the heat sensitive sensor, so as to confirm whether the battery needs to be replaced. According to the invention, the cost of operators is saved, the service efficiency of the battery is improved, and the quantity of standby batteries is reduced.

Description

technical field [0001] The invention relates to the technical field of electric bus charging, in particular to an electric bus battery detection and replacement method. Background technique [0002] Electric vehicle replacement stations mainly use the method of replacing batteries for electric vehicles to supplement electric energy for electric vehicles. Compared with charging electric vehicles through charging piles, it saves time, increases the convenience of electric vehicle owners, and is conducive to the development of electric vehicles. universal. [0003] The existing electric vehicle replacement station is to replace the original battery on the electric vehicle with a fully charged battery. This method is more convenient for the owner of the family car, but it is not suitable for the electric bus with a long mileage and frequent battery replacement. , because the number of buses is large, the number of vehicles is large, the regularity of departures is strong, and t...
