Multi-channel output coordinated control electric vehicle integrated charger monitoring system and method

Abstract

The invention discloses a multi-channel output coordinated control electric vehicle integrated charger monitoring system and method, including a voltage and current implementation demand acquisition module, an optimal strategy customization module and a strategy execution module; the voltage and current real-time demand acquisition module will The optimal strategy customization module is transmitted to the optimal strategy customization module, and the optimal strategy customization module provides the demand to the strategy execution module, and the strategy execution module feeds back the execution result to the optimal strategy formulation module, and the optimal strategy customization module outputs the result to Voltage and current real-time demand acquisition module; the beneficial effect of the present invention: adopting the power intelligent assembly method, by adjusting the module voltage, current, and multi-module online and offline status, the optimal power output strategy can be selected in real time to solve the problem of electric vehicle charging. Security, real-time, and diversity of power, voltage, and current requirements.

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
