Electrochemical reactions and current flows in Li-Ion batteries generate heat and the associated temperature**rise has negative impacts on the performance, safety and lifetime of the batteries. An effective battery thermal**management system is therefore required to keep the whole battery pack temperature below 45ºC and ensure**cell-to-cell temperature variations below 5ºC. Current cooling technologies are either inefficient at maintaining**uniform temperature or add significant weight and cost to the battery pack. Our patent-pending low-cost**battery thermal management technology based on polymeric heat pipes will keep battery cells at the**recommended temperature range to prevent overheating, increase battery life and higher driving range in**electric vehicles. The use of polymer instead of metal for the heat pipe fabrication reduces the weight and cost**significantly. We have developed a prototype and are currently working with strategic partners (including**BRP) to advance the technology. The preliminary path for commercialization of the technology will be**through a spin-off company, which includes the two main inventors. A market assessment is now required**given the rapidly growing (CAGR of 27.6%) and segmented market of electric vehicles, including niche**markets such as industrial electric vehicles, recreational vehicles, drones, electric aircraft, electric boats, robots**and forklifts. This study will quantify the market opportunity, define the competitive landscape, identify the**barriers to entry and market trends as well as evaluate technology adoption and product positioning. Doing so**will allow us to define the path towards commercialisation and contribute to the global adoption of electric**vehicles and the consequent reduction in CO2 emissions.

锂离子电池中的电化学反应和电流流动会产生热量，由此产生的温升会对电池的性能、安全性和寿命产生负面影响。因此，需要一个有效的电池热管理系统**来将整个电池组的温度保持在45°C以下，并确保**电池与电池之间的温度变化低于5°C。目前的冷却技术要么在维持**均匀温度方面效率低下，要么大大增加了电池组的重量和成本。我们正在申请专利的基于聚合物热管的低成本电池热管理技术将使电池保持在**推荐的温度范围内，以防止电池过热，延长电池寿命并提高**电动汽车的续航里程。用聚合物代替金属制造热管，大大降低了重量和成本。我们已经开发了一个原型，目前正在与战略合作伙伴(包括**BRP)合作推进这项技术。这项技术商业化的初步路径将是**通过一个包括两个主要发明者在内的剥离公司。鉴于电动汽车的快速增长(年复合增长率为27.6%)和细分市场，包括工业电动汽车、休闲车、无人机、电动飞机、电动船只、机器人**和叉车等利基市场**，现在需要进行市场评估。这项研究将量化市场机会，确定竞争格局，确定进入壁垒和市场趋势，并评估技术采用和产品定位。这样做**将使我们能够确定商业化的道路，并为全球采用电动**汽车和随之而来的二氧化碳排放减少做出贡献。
