Abstract: AC charging pile, commonly known as "slow charging pile", is fixedly installed outside the electric vehicle and connected to the AC grid. The national standard adopts 220V single-phase alternating current on the power supply device that provides AC power on-board chargers for electric vehicles (that is, the chargers that fixedly installed on electric vehicles). The national standard GB51348-2019 stipulates that it should be equipped with current-limiting electrical fire protection devices in the places for reserve warehouses, electric vehicle charging and so on. Electrical fire-resistant current-limiting protectors can effectively overcome the disadvantages such as high current during short-circuit, long time to cut off short-circuit current, large arc sparks generated during short-circuit, and short service life of the traditional circuit breakers like air switches and monitoring equipments.When a short-circuit fault occurs,it can quickly limit the short-circuit current at a microsecond speed to achieve arc extinguishing protection, which can significantly reduce electrical fire accidents and ensure the safety of personnel and property on site.

0 行业背景

      由于条件的发展壮大，条件维护是大部分人类历史命運一致体的作业。新能源汽车这是由于并还没有汽车尾气废气排放，不容易生成一空气氧化反应的碳，二空气氧化反应的碳，氮空气氧化反应的合物等损害物资，并还没有燥音空气弄脏，对条件空气弄脏较小，各国也为此提供优惠政策鼓励电动车科技的普及。

      With the development of the world, environmental protection has become the task of the human community with a shared future. Because new energy vehicles have no exhaust emissions, no harmful substances such as carbon monoxide, carbon dioxide, nitrogen oxides, no noise pollution, and less environmental pollution, governments around the world also provide preferential policies to encourage the popularization of electric vehicle technology.

      交流充电桩俗称“慢充桩"，固定安装在电动汽车外、与交流电网连接，国标采用 220V 单相交流电，为电动汽车车载充电机（即固定安装在电动汽车上的充电机）提供交流电源的供电装置。交流充电桩只提供电力输出，没有充电功能，需连接车载充电机为电动汽车充电，只起到控制电源的作用的。其采用符合国标的交流充电模式，输出功率不高于 7kW，一般车辆电池从 0 到充满需要 5-8 小时，具体情况视不同车型动力电池容量及实际充电功率而定。

      AC charging pile, commonly known as "slow charging pile", is fixedly installed outside the electric vehicle and connected to the AC grid. The national standard adopts 220V single-phase alternating current on the power supply device that provides AC power on-board chargers for electric vehicles (that is, the chargers that fixedly installed on electric vehicles). The AC charging pile only provides power output and has no charging function. It needs to be connected to the on-board charger to charge the electric vehicle, which only plays the role of controlling the power source. It adopts an AC charging mode that conforms to the national standard, and the output power is not higher than 7kW. Generally, it takes 5-8 hours for a vehicle battery to be fully charged from 0. The specific situation depends on the capacity of the power battery of different models and the actual charging power.

      对于电动车充电桩，国家标准GB51348-2019《民用建筑电气设计标准》中13.5.5规定，储备仓库、电动车充电等场所的末端回路应设置限流式电气防火保护器。

3 产品应用

      我们对沟通交流充能桩，寻常会用于布局用电的措施，要你是在户外立柱装有使用，充能桩布局在几个所在地址，所在地址特别增溶，每位充能桩都去装有使用组合件防震限免疫印迹保养区器，特别找麻烦，况且是没有装有使用所在地址，况且防止规范要求较高。要你是棚内挂墙装有使用，保养区器装有使用在水泥墙需用挤占需要所在地址。而用于协调布局装有使用的措施，便利管理工作和运营维护。

      For AC charging piles, centralized power supply is generally used. If it is installed outdoor, the charging piles are distributed in multiple locations, and the positions are relatively scattered. It’s trouble to install electrical fire-resistant current-limiting protector on every charging pile,and also,there is no installation location and the requirement of waterproof is really high.. If it is installed on the wall indoor, the protector needs a certain position.However, the unified and centralized installation way is convenient to manage and maintain.
