Detection apparatus of off-board direct-current charger

Abstract

Provided in the invention is a detection apparatus of an off-board direct-current charger. The detection apparatus consists of an interface module, a voltage conversion module, an information acquisition and communication module, a main processor module, a bluetooth module, and a load module. The detection apparatus simulates an electric car to send a charging message signal to an off-board direct-current charger; the off-board direct-current charger charges the load module of the detection apparatus; and the detection apparatus detects a charging parameter of the off-board direct-current charger. A testing worker checks a testing result by a smart phone; the smart phone downloads local unit electric charge at that time from a cloud server and conversion of a charging charge is carried out automatically. The smart phone can upload the testing result to the cloud server, thereby carrying out a detection data analysis and mining further. The testing worker also can use the smart phone to download a latest program of the apparatus; the smart phone sends the program to the main processor module of the detection apparatus by the bluetooth module of the detection apparatus, thereby realizing remote upgrading of the detection apparatus.

Description

technical field [0001] The invention relates to a detection device for a non-vehicle DC charger. Background technique [0002] With the popularization of new energy electric vehicles, there are more and more corresponding non-vehicle DC chargers. In order to unify the non-vehicle DC chargers on the market, the country avoids the fact that some off-vehicle DC chargers and some electric vehicles are not equipped with each other. Can not be charged, resulting in waste, so the general standard GB / T27930-2011 communication protocol between off-vehicle DC charger and battery management system and GB-T20234.3-2011 DC charging interface standard were formulated. In this way, if off-vehicle DC charger manufacturers and electric vehicle manufacturers formulate products according to these agreements, they can be equipped with each other to realize the maximum utilization of resources. [0003] At present, several general-purpose devices are needed on the market to meet the detection r...

Problems solved by technology

However, most of the off-vehicle charging devices currently adopt the GB / T27930-2011 communication protocol, because the protocol standard does not stipulate that the charging rate must be sent, so for off-board charging devices that do not send the signal, the detection system and The detection method will not be able to count the charging amount because it does not know the billing rate

Second, the detection system and detection method are not easy to carry and manage due to the need to use too many equipment such as DC standard meters, AC standard meters, and DC electronic loads.
