Second Life Batteries for Commercial Energy Use

Brill Power、AceOn Group和克兰菲尔德大学正在合作一个项目，在克兰菲尔德的数字航空研究和技术中心设计、建造和安装一个智能的二次电池系统，该系统由升级回收的电动巴士电池制成。电池系统将与太阳能光伏阵列和逆变器连接，将太阳能反馈到克兰菲尔德校园的当地电网。这将有助于克兰菲尔德通过最大限度地利用可再生太阳能来减少能源消耗。克兰菲尔德大学在其克兰菲尔德校区拥有超过1MWp的太阳能光伏发电，并正在寻找低成本，可持续的能源存储解决方案，以帮助将太阳能发电与电力需求相匹配。该大学还获得了8个二手电动巴士电池，该大学希望将其升级循环用于储能。升级锂离子电池具有挑战性，因为老化电池的性能可能存在很大差异，而传统电池系统的强度和寿命取决于最弱的电池。Brill Power开发了一种新颖的电池管理系统（BMS），可以弥补电池性能上的这些差异，并确保最大的使用寿命、性能和安全性。AceOn集团在设计和制造电池系统方面拥有超过25年的经验，并将使用Brill Power的BMS和Cranfield的二手电动客车电池来制造智能二次寿命电池。合作伙伴将共同创建并展示一种采用循环经济方法的新型储能系统，这将帮助克兰菲尔德大学减少能源使用的碳排放，并节省电费。该项目还将帮助Brill Power和AceOn Group为这项新技术更广泛的商业推广制定蓝图。该项目将使合作伙伴能够克服COVID-19大流行带来的一系列挑战，包括能源存储行业的商业机会减少，克兰菲尔德大学由于校园学生和教职员工数量减少而直接使用太阳能的减少，以及缺乏资金和项目机会将使用过的电动公交车电池重新用于固定能源存储。

Brill Power, AceOn Group and Cranfield University are collaborating on a project to design, build and install a smart, 2nd life battery system at Cranfield's Digital Aviation Research and Technology Centre, made from up-cycled electric bus batteries. The battery system will be connected with a solar PV array and an inverter to feed solar energy back to the local grid at Cranfield campus. This will help Cranfield decarbonise its energy use by maximising the use of renewable solar energy.Cranfield University has more than 1MWp of solar PV generation on its Cranfield campus and is looking for low-cost, sustainable energy storage solutions to help match solar generation with electricity demands. The university also has access to 8 used electric bus batteries, which the university would like to up-cycle for use in energy storage. Upcycling lithium-ion batteries is challenging because there can be large differences in the performance of aged battery cells and conventional battery systems are only as strong and live as their weakest cells. Brill Power has developed a novel battery management system (BMS), which compensates for these differences in cell performance and ensures maximal lifetime, performance and safety. AceOn Group has more than 25 years of experience in designing and manufacturing battery systems and will create a smart 2nd life battery, using Brill Power's BMS and Cranfield's used electric bus batteries. Together, the partners will be able to create and demonstrate a novel energy storage system with a circular economy approach, which helps Cranfield University decarbonise its energy use and save electricity bills. The project will also help Brill Power and AceOn Group create a blueprint for a broader commercial roll-out of this novel technology.The project will enable the partners to overcome a number of challenges created by the COVID-19 pandemic, including fewer commercial opportunities in the energy storage industry, lower direct use of solar energy at Cranfield University due to lower student an staff numbers on campus, and a lack of funding and project opportunities to re-purpose used electric bus batteries for stationary energy storage.
