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.

在所有电动汽车应用中——包括全电池供电的电动汽车、插电式混合动力汽车和燃料电池车型——电池对于车辆的整体成本和性能至关重要，尤其是在整个生命周期内。然而，尽管锂离子电池继续在电动汽车领域占据主导地位，但没有一种单电池化学成分能够针对汽车制造商所针对的所有电池特性进行优化，包括：*能量密度*功率和脉冲弹性*工作温度范围*循环寿命*对因此，基于单一化学成分的热失控*成本电动汽车电池无法调和尺寸、功率和工作温度与可预测性、使用寿命和成本之间相互矛盾的要求。由于安全是首要任务，最终的设计不可避免地会影响性能，并且越来越依赖高稀土含量的电池（例如钴）。这给 OEM 电气化计划和最终用户采用带来了重大障碍。作为回应，升级技术工程正在开发一种新型电池管理系统，该系统具有在复合电池模块中实际集成多种电池化学成分的潜力：多化学电池 (MCB)。选择每种电池化学物质来弥补其他电池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的挑战，释放了英国供应链的重要机遇。现在，与克兰菲尔德和 ASPIRE Engineering 一起升级技术工程，目标是硬件和模型 -推动嵌入式软件开发以实现全尺寸模块化原型，作为证明硬件切换多种化学物质的可扩展性并支持英国供应链参与的基础。
