Chimera: an intelligent battery management architecture for next-generation electric vehicle batteries using multiple cell chemistries

在所有电动汽车应用中，包括全电池驱动的电动汽车、插电式混合动力车和燃料电池变种，电池对车辆的总体成本和性能至关重要，特别是在整个生命周期。然而，尽管锂离子继续在电动汽车领域占据主导地位，但没有任何单一电池化学物质在汽车制造商瞄准的所有电池特性上进行优化，包括：*能量密度*功率和脉冲弹性*工作温度范围*循环寿命*对热失控的敏感性*成本因此基于单一化学物质的电动汽车电池无法调和尺寸、功率和工作温度与可预测性、寿命和成本之间的冲突要求。由于安全是根本的优先事项，由此产生的设计不可避免地影响了性能，越来越依赖高稀土含量的电池(例如钴)。这给OEM电气化计划和终端用户的采用带来了巨大的障碍。对此，升级技术工程公司正在开发一种新型的电池管理系统，该系统有可能将多种电池化学物质实际集成到一个复合电池模块中：多化学电池(MCB)。通过选择每个单元化学物质来缓解其他细胞化学物质在所有关键指标上的弱点，MCB通过克服平衡化学物质和功率调节方面的挑战，释放了英国供应链的巨大机遇。现在，升级技术工程公司与Cranfield和Aspire Engineering合作，瞄准硬件和模型驱动的嵌入式软件开发，以实现全面的模块化原型，作为证明硬件切换到多种化学物质的可扩展性并支持英国供应链活动的基础。

Across all electric vehicle applications - including fully battery powered electric vehicles, plug-in hybrids and fuel cell variants - the battery is critical to overall vehicle cost and performance, especially over the full lifecycle. However, despite Lithium-ion continuing to dominate the EV domain, no single cell chemistry is optimised across all of the battery characteristics targeted by vehicle manufacturers, including:* Energy density* Power and impulse resilience* Operating temperature range* Cycle life* Susceptibility to thermal runaway* CostElectric vehicle batteries based on single chemistries therefore cannot reconcile the conflicting requirements for size, power and operational temperature versus predictability, lifespan and cost. With safety the underlying priority, the resulting design compromises inevitably impact performance, with increasing reliance on cells with high rare earth content (e.g. Cobalt). This presents significant barriers to OEM electrification programmes and end-user adoption.In response, Upgrade Technology Engineering are developing a novel battery management system with potential to practically integrate multiple cell chemistries within a composite battery module: the Multi-Chemistry Battery (MCB). With each cell chemistry selected to mitigate the others' weaknesses across all key metrics, MCB unlocks a significant UK supply chain opportunity by overcoming challenges of balancing chemistries and power regulation.Now Upgrade Technology Engineering, with Cranfield and ASPIRE Engineering target the hardware and model-driven embedded software developments to realise a full-scale modular prototype, as the basis to prove hardware switching scalability to multiple chemistries and support UK supply chain engagements.
