New and proposed electric vehicles (EV) will fast charge at very high rates while briefly stopped on long distance travels. This places significant stress on the existing electrical distribution grid. Instead of adding new "poles and wires", charging stations can be "battery-backed" by adding stationary batteries. eCamion is a Canadian developer and manufacturer of battery energy storage systems. They have deployed these throughout Ontario and are presently contracted to deliver new higher power systems. eCamion's market is evolving to faster charging rates and their present battery cooling system is no longer sufficient to maintain uniform cool temperature during high rate operation. There is a need for new thermal management techniques to keep such stationary batteries cool while operating at very high rates (4C+). Whereas the EV might take hours to discharge, the battery backed storage at the charge station must discharge in minutes, and potentially to multiple EVs simultaneously. In this research project, new and novel battery thermal conditioning systems will be explored to determine their performance enhancement while remaining within the original footprint of the charge station. The project has three phases. First, the existing battery thermal conditioning system will have its performance evaluated using high resolution electrical and thermal measurement techniques to create a well-defined and comprehensive picture of thermal response. Second, new forced-air and/or phase-change-material systems will be designed to address non-uniformity (e.g. hot-spots) and insure overall cooling rate is met. Finally, the new design will be trialed in a system to demonstrate its performance in the application. It is expected that this NSERC Engage Project will lead to a long-term academic-industrial relationship given the massively expanding energy storage market and product evolution. Two new HQP will be trained and this project supports the Canadian Government's initiatives for electric vehicles and fast charging.

新的和拟议的电动汽车（EV）将以很高的速度快速充电，同时短暂停下来长途旅行。这对现有的电分布网格施加了重大压力。可以通过添加固定电池来“贴上电池支持”，而不是添加新的“杆和电线”。 Ecamion是加拿大开发人员和电池储能系统的制造商。他们在整个安大略省都部署了这些部署，目前已签约以提供新的更高电力系统。 Ecamion的市场正在发展为更快的充电速率，并且他们目前的电池冷却系统不足以在高速公路运行期间保持均匀的凉爽温度。 需要新的热管理技术，以使此类固定电池以非常高的速度运行（4C+）保持冷却。电动汽车可能需要几个小时才能放电，而电池的电池备用存储必须在几分钟内放电，并可能同时分配到多个电动汽车。 在该研究项目中，将探索新的和新颖的电池热调理系统，以确定其性能提高，同时保留在电荷站的原始足迹中。该项目有三个阶段。首先，现有的电池热条件系统将使用高分辨率的电气和热测量技术对其性能进行评估，以创建明确且全面的热响应图片。其次，将设计新的强制空气和/或相变材料系统来解决不均匀性（例如热点），并确保确保总体冷却速率。最后，新设计将在系统中进行试用，以证明其在应用程序中的性能。 预计该NSERC参与项目将导致长期的学术工业关系，鉴于储能市场和产品的发展大大扩展。将对两个新的HQP进行培训，该项目支持加拿大政府的电动汽车计划和快速充电计划。
