Charging control method of mechanical parking equipment and control device thereof

Abstract

The present invention provides a charging control method of mechanical parking equipment and a control device thereof, wherein a three-phase power supply of the mechanical parking equipment is used for taking out a plurality of single-phase power supplies for charging with excellent balance. For taking out a plurality of single-phase power supplies for charging electric vehicles from the three-phase power supply for the power of the mechanical parking equipment, the contacts of each two-phase electromagnetic contactor, which are combined for taking single-phase power from the three-phase power supply, are controlled for selectively switching the contacts of each electromagnetic contactor thereby selecting two phases of the three-phase power, monitoring the charging states of a plurality of electric vehicles and preventing current balance deterioration.

Description

Technical field [0001] The invention relates to a charging control method and a control device for charging a plurality of parked electric vehicles in a mechanical parking facility. Background technique [0002] Traditionally, as a mechanical parking device for parking vehicles, various parking devices such as elevator type, plane reciprocating type, puzzle mobile type, multi-layer type, etc. are used according to installation conditions. [0003] On the other hand, in recent years, electric vehicles using an electric motor as a power source (the “electric vehicle” in this specification and claims refers to a vehicle that can be driven by an electric motor (including a combined use with an engine)) has become widespread. Since such electric vehicles can reduce exhaust emissions and are conducive to environmental protection, the fuel used in the past is no longer necessary, but instead, the battery must be charged. Therefore, a parking device with a function capable of being charge...

AI Technical Summary

Problems solved by technology

Therefore, it is considered to introduce a single-phase dedicated electric wire for electric vehicle charging to the mechanical parking equipment, but in this case, the scale of the primary power supply equipment of the mechanical parking equipment must be increased, and the initial cost of construction will increase.

In addition, the basic charge of the electricity bill increases, and the maintenance cost also increases

[0006] Moreover, in the existing mechanical parking equipment, it is often difficult to enhance the existing power supply equipment. In order to have a charging function, more construction costs may be required
