Wireless performance monitoring of plug-in electric vehicules

插电式电动汽车（PEV）承诺是一种清洁，廉价的替代石油汽车，占加拿大温室气体排放量的30%。PEV的更安静，有良好的扭矩和需要较少的维护。然而，PEV每次充电提供有限的范围，这导致众所周知的范围焦虑。此外，每个PEV需要大量的电力和时间来充电。随着大量的PEV很快预计在街道上（超过一百万，到2015年在美国），不受控制的PEV充电可以过载的配电变压器和破坏电网。目前，公用事业提供商无法知道消费者何时以及如何对他们的PEV充电。这对电力供应商造成了需求焦虑。该项目的成果将缓解这些忧虑。 PEV可以被认为是智能电网的移动的部分。离网时没有连接。 然而，公用事业提供商正在寻找与PEV持续通信的方法，以更好地预测和管理充电过程。此外，用户以及PEV制造商有兴趣了解PEV的功耗特性以及它如何随各种操作条件而变化。 在这个项目中，将开发一个具有相关算法的硬件和软件无线系统，以管理PEV和智能电网之间的交互。在每个PEV中将存在无线模块，该无线模块将在内部收集PEV的真实的时间能量性能数据并与电网进行通信。这将有助于更好地了解实际驾驶条件下高度非线性的电池充放电特性。充电站的另一个子系统将传输充电相关数据（费率）。时间等）到电网，并实现公共充电站的无缝使用的认证和自动计费。 因此，所提出的系统将有助于电网更好地预测和管理PEV充电过程。测量的PEV功耗特性将通过互联网和智能手机提供给感兴趣的人。

Plug-in electric vehicles (PEVs) promise a clean, inexpensive alternative to petroleum vehicles that account for 30% of greenhouse gas emissions in Canada. PEV's are quieter, have good torque and require less maintenance. However, PEV's offer limited range per charging which causes the well known range anxiety. In addition, each PEV requires significant amount of electricity and time to recharge. With large number of PEVs soon expected in the streets (over one Million by 2015 in US), uncontrolled PEV charging can overload the distribution transformers and disrupt the power grid. Currently the utility provider has no means of knowing when and how connsumers will charge their PEVs. This has caused the demand anxiety to the electricity provider. The outcome of this project will alleviate these anxieties. The PEV can be considered as the mobile portion of the smart grid. There is no connectivity when it is off-grid. However, the utility provider is looking for ways to communicate with the PEV continuously to better predict and manage the charging process. In addition, the user as well as the PEV manufacturers have interest to understand the power consumption characteristics of the PEV and how it varies with various operating conditions. In this project, a wireless system in hardware and software with associated algorithms will be developed to manage the interaction between the PEV and the smart grid. There will be a wireless module in each PEV that will internally collect and communicate real time energy performance data of the PEV with the grid. This will enable better understanding of the highly nonlinear battery charging/discharging characteristics under actual driving conditions. Another sub system at the charging stations will transmit charging related data (rate. time etc) to the grid and enable authentication and automatic billing for the seamless usage of public charging stations. Hence, the proposed system will help the grid to better predict and manage the PEV charging process. The measured PEV power consumption characteristics will be available over the Internet and smart phones for those interested.
