Hybrid Electric Vehicles (HEVs) are currently considered the most viable alternative propulsion system in automotive industry. They offer a wide range of improvements from most efficient fuel consumption, ability to fuel from the grid, and emission reduction to enhanced power performance. The performance of HEVs heavily depends on the efficiency and reliability of the electric battery pack which is the most important component of the propulsion system. The complexity of the hybrid powertrain decision making combined with the power requirement of the heating, ventilating and air conditioning (HVAC) system make the energy management of HEVs a tremendous challenge which, for the most part, has not been adequately resolved. This research will utilize an experimental-theoretical strategy which aims to develop an integrated intelligent energy management system that encompasses the development of: i) battery state estimation system with prognostics and diagnostics; ii) battery thermal management system that enables both cooling and heating of the battery pack to maintain the optimum temperature under various driving and climate conditions; iii) HVAC system; and iv) cooling of electronics on board HEVs. A unique state-of-the-art testing facility will be established at SFU to validate the simulations, and more importantly, to optimize the prototypes proposed in this research. The ultimate goal is to develop efficient energy management system(s) to reduce the cost, weight, and ensure long term, problem-free operation while increasing the driving range of HEVs.

混合动力电动汽车（HEV）目前被认为是汽车行业最可行的替代推进系统。它们提供了广泛的改进，从最有效的燃料消耗、从电网提供燃料的能力、减少排放到增强的电力性能。混合动力汽车的性能在很大程度上取决于电池组的效率和可靠性，电池组是推进系统最重要的组成部分。混合动力系统决策的复杂性加上加热、通风和空调 (HVAC) 系统的功率要求，使混合动力汽车的能源管理成为一项巨大的挑战，而该挑战在很大程度上尚未得到充分解决。本研究将采用实验理论策略，旨在开发集成智能能源管理系统，其中包括：i）具有预测和诊断功能的电池状态估计系统； ii) 电池热管理系统，使电池组能够冷却和加热，以在各种驾驶和气候条件下保持最佳温度； iii) 暖通空调系统； iv) HEV 车载电子设备的冷却。 SFU 将建立一个独特的、最先进的测试设施来验证模拟，更重要的是，优化本研究中提出的原型。最终目标是开发高效的能源管理系统，以降低成本、重量并确保长期无问题运行，同时增加混合动力汽车的行驶里程。
