电动汽车充电基础设施的未来：大规模部署的挑战

 

This acceleration means that more charging station infrastructure will be needed to keep these cars moving when they’re away from home. 

 

Today, depending on where you’re located, it can be difficult to find a station to recharge an EV—but that will soon change. The U.S. Department of Energy says there are tens of thousands of chargers available in key areas of the country as a supplement to residential charging right now. But with a growing interest in EVs, plus the federal government’s funding commitment through programs like the Bipartisan Infrastructure Law and Inflation Reduction Act, the International Energy Agency (IEA) predicts that more than 1.3 million EV chargers will be deployed across the United States in the coming years. 

 

These chargers will start to appear in places like retail centers, airports, downtown districts, college campuses, workplaces, restaurants and even new charging stations along highways. 

An inside look at EV chargers and how they communicate

EV chargers are a great example of the ultimate IoT device. Lots of intelligence is required to support their capabilities and performance levels.

 

On one end of the charger is the power grid, which feeds electricity to the charger. On the other end is an electric car being charged. And in between is where all the fun stuff happens!

 

What’s going on inside an EV charger—and why does it matter?

 

Several devices and components work hard to support specific purposes within the charger and make sure it functions as expected: 

• A device to manage power 
• A device to complete payment transactions (credit card, tap-to-pay or something else) 
• A device to display content like advertising or policy information 
• An on-board controller to manage everything 

These devices all need to talk to one another inside the charger, and some need the capability to talk to an outside system as well. For example, the device that handles payments must be able to validate the user’s bank information or subscription membership before power is allowed to flow.

 

This means that, in addition to the cabling itself, a managed network complete with a WAN connection and remote access capabilities is a must to provide the connectivity that these systems need.

 

虽然旧式电动汽车充电器可能依靠离散 I/O 控制来完成部分通信，但新型设备通过使用以太网系统进行通信，将智能融入到通信过程中。托管以太网网络提供：

• 可靠的基础设施，供车载系统通信
• 用于WAN连接的蜂窝选项 
• 安全VPN访问，用于与系统的远程交互 

 

随着更多充电器的部署，它们产生的数据流量也会增加。当多个充电器安装在一个地方（例如购物中心停车场）时，它’与尝试与每个充电器进行单独通信相比，通过链接到后端系统的单个连接来传输流量是最有效的。精心设计的网络可以适应这种情况，而无需牺牲其网络安全态势。  

大规模部署充电桩：远程和安全连接至关重要

随着充电器的大规模部署，远程支持将成为维持优质客户服务的关键。 

它赢了’对于制造商或分销商来说，派遣技术人员到各个充电器处排除故障、解决问题或进行预防性维护是不切实际的。远程管理这项工作可以节省时间和金钱。

 

但如果操作不当，远程连接可能会暴露潜在的网络安全漏洞。选择安全的远程解决方案和服务来支持电动汽车充电站 对于保护数据至关重要，例如用户’ 个人信息和公司记录，更不用说确保资产正常运行时间。

 

确保这种可用且安全的连接保持持久也很重要。在大多数 WAN 连接（包括蜂窝连接）中，您不需要’t 自己的 IP 地址。当网关连接时（以及此后定期），会向网关分配 IP 地址。地址的动态特性使得分布式系统难以交互。

 

那’持久数据网络 (PDN) 等解决方案 百通地平线 开始发挥作用。它为终端设备提供中性接地，以便安全地连接到公共点。这减少了云系统和网络中每个充电器之间不安全消息传递和手动创建的 VPN 连接的需要。可以想象，一旦一个城市、州、国家或大陆出现数百或数千个充电器，手动方式很快就会变得不可持续且不切实际。

 

百通’的汽车团队可以帮助您安全、大规模地部署电动汽车充电站基础设施，以便您可以自信地支持远程监控和管理，从而最大限度地提高效率并提供出色的支持。对电动汽车充电规划或基础设施有疑问吗？联系我们的汽车专家。
