远程升级直流充电机系统设计

Design of Remote Upgradable DC Charger System

传统的电动汽车充电机在升级文件传输时一般会影响充电业务,不能断点续传,也不能批量同时升级,更无法对充电机内部其它各组件升级,给维护带来了诸多不便。根据充电机运营管理的实际情况,设计了远程升级直流充电机系统以及升级方法。该系统在升级文件传输过程中不影响充电机正常的充电业务、数据通信和人机操作;不但支持断点续传,充电机批量升级,而且支持充电机内各组件升级。该系统及方法安全、稳定、有效。

The traditional charger of electric vehicle will generally be affected when the upgrade file is being transmitted.The charger can not resume transmitting a upgrade file from a breakpoint,nor can lots of chargers be upgraded at the same time,nor can the charger upgrade its inner components,which brings a lot of inconvenience to maintenance.According to the actual operation and management situation of charger,a remote upgradable charger system and method has been designed.It does not affect the normal charging business,data communication and manmachine operation of the charger during the upgrade file transmission process.It not only supports resuming transmission the upgrade file that is paused,it supports upgrading a batch of chargers simultaneously and is able to update of various components inside the charger as well.The system and method are safe,stable and effective.
