System and method for monitoring integrated charger of multiplexed output coordination control electric automobile

Abstract

The invention discloses a system and method for monitoring an integrated charger of a multiplexed output coordination control electric automobile. The system comprises a voltage and current real-time requirement acquisition module, an optimal strategy customizing module and a strategy execution module. The voltage and current real-time requirement acquisition module transmits requirements to the optimal strategy customizing module, the optimal strategy customizing module provides the requirements for the strategy execution module, the strategy execution module feeds an execution result back to the optimal strategy customizing module, and the optimal strategy customizing module outputs the result to the voltage and current real-time requirement acquisition module. The system and method for monitoring the integrated charger of the multiplexed output coordination control electric automobile has the advantages that an optimal power output strategy is selected by adopting an intelligent power allocation mode and adjusting voltage and current of the modules and multiple-module on-line and off-line states in real time, and the problems of the safety, the real-timeliness and the variety of the power, voltage and current requirements in the charging process of the electric automobile are solved.

Description

technical field [0001] The invention relates to a multi-channel output coordinated control system and method for monitoring an electric vehicle integrated charger. Background technique [0002] With the challenges of energy demand and resource environment to human beings, the number of electric vehicles is increasing, and the number of supporting charging infrastructure equipment is also increasing. The impact of charging on personnel safety and power grid is getting more and more attention. Therefore, A safe and reliable monitoring system for electric vehicle chargers will play an important role. [0003] Existing monitoring systems for electric vehicle chargers often stay on routine collection and basic control, without considering monitoring strategies based on working status, and there is no optimal strategy selection, and there is no solution for problems encountered during charging. Flexible and reasonable charging schemes and protection schemes lead to great safety h...

AI Technical Summary

Problems solved by technology

[0005] 1 In the prior art, the integration of multi-channel output coordinated control electric vehicle chargers and charging piles has not yet been considered, and the monitoring system and monitoring method for integrated chargers have not been involved, and the existing monitoring systems can only Collecting the data of one power output port of the charger cannot collect the data of multiple power output ports of the charger, let alone how to process the data of multiple power output ports;

[0006] 2 The charging output of the mentioned charger does not have a multi-channel output function

When multiple electric vehicles need to be charged at the same time, the charger does not provide multiple power output interfaces. For a site with a small number of charging devices, it needs to wait for a long time, resulting in long scheduling time for electric vehicles and low efficiency utilization of the charger;

[0007] 3 The policy customization function of the mentioned charging scheme is weak

For the factors that appear in the work of the charger, there is a lack of clear division of working states. For various factors that appear in different working states, it only stays at the level of routine collection and basic control, lacks comprehensive evaluation and analysis, and does not provide timely guidance. Evaluate and analyze the results to make the optimal charging strategy and protection strategy, but the problem is often not dealt with in a timely and accurate manner, resulting in misjudgment, false alarm, repeated operations, and implicitly increasing the workload of personnel to troubleshoot problems
