Abstract

The invention discloses an electric vehicle storage battery charging device, which comprises a shell, wherein an AD/DC converter connected with a grid power supply line is fixed inside the shell; a controller connected with the AD/DC converter in a signaling manner, and a detection chip connected with the controller. Detection contents of the detection chip comprise the electric quantity of a storage battery, a temperature of the storage battery, a frequency of a grid and charging and discharging current values. The electric vehicle storage battery charging device has the advantages that by the adoption of the device for charging and discharging an electric vehicle storage battery, when a large quantity of devices are applied to the grid, automatic adjustment of electrical loads on user sides is realized; and effects are as follows: firstly, ''load shifting'' reduces a difference between peak and valley of the grid and relieves the scheduling pressure of the grid, and secondly, the regional power supply capacity demand is lowered. The technical measure of the invention can realize friendly interaction between the electric vehicle storage battery and the grid, so that the economicalbenefit of a user is guaranteed, and an auxiliary function realizes the friendly interaction between the storage battery and the grid and realizes the load shifting of the grid.

Description

technical field [0001] The invention belongs to the technical field of charging devices, in particular to a charging device for batteries of electric vehicles. Background technique [0002] The power grid is a channel that sends electric energy from the power generation end to the user, and adjusts the energy balance at both ends. However, with the continuous increase of the power grid capacity and power consumption, the peak-to-valley difference is also increasing, which leads to the dispatching of the power grid. The pressure and difficulty are constantly increasing. [0003] At present, electric vehicles are developing continuously and rapidly. The charging time of vehicles with the largest transportation function is after going to work and after returning home. These two are the peak hours of electricity consumption of the power grid. When the charging device is charging, it does not have the ability to automatically adjust the working mode, and the support for the grid...
