Intelligent charging pile for electric vehicle storage battery

Abstract

The invention discloses an intelligent charging pile of an electric vehicle storage battery, which belongs to the field of an intelligent charging and discharging device of a storage battery. The intelligent charging pile comprises a PLC (programmable logic controller) industrial control system inside a shell, wherein the electric vehicle storage battery is arranged outside the shell. The intelligent charging pile is characterized in that a wiring terminal, an intelligent rectifying and inverting module and the electric vehicle storage battery are orderly connected with one another through a lead; the control end of the intelligent rectifying and inverting module is connected with the PLC industrial control system; an alternating current contactor contact is arranged on an inlet lead; a charging inverting control switch is arranged on the lead between the intelligent rectifying and inverting module and the storage battery; the control ends of an alternating current contactor and the charging inverting control switch are connected to the PLC industrial control system; a touch screen is arranged at the data end of the PLC industrial control system; and a wiring terminal, the touch screen and a storage battery interface are arranged on the shell. The intelligent charging pile is suitable for various storage batteries, for example, a lead-acid storage battery, a maintenance-free storage battery, a nickel-cadmium accumulator and a lithium iron phosphate battery, can protect the electric vehicle storage battery, can be used for charging quickly and fully, and is high in safety performance, long in service life and simple to operate.

Description

technical field [0001] The invention provides an intelligent charging pile for storage batteries of electric vehicles, which belongs to the field of intelligent control charging equipment for storage batteries. Background technique [0002] Because of its low manufacturing cost, large capacity, and low price, and its role in replacing other energy sources, lead-acid batteries have been widely used and have broad development prospects. However, if it is not produced and used properly, its life will be greatly shortened. There are many factors that affect the life of lead-acid batteries, and the correct charging method can effectively prolong the service life of the battery. The research found that during the production and use of batteries, the charging process has the greatest impact on battery life. In other words, the vast majority of batteries have already determined their service life during production. [0003] The existing electric vehicle chargers have a simple cha...
