Li-Ion batteries dominate the energy storage in both portable and as fixed power installations in Electrical vehicles. Testing of these devices is by nature time consuming as they undergo charge and discharge cycles while the open circuit voltage is monitored as function of time, sometime taking up to 3 weeks for the process to qualify the batteries.
锂离子电池在便携式和电动汽车固定电源装置中的能量存储中占据主导地位。这些设备的测试本质上是耗时的，因为它们会经历充电和放电循环，同时会随着时间的推移监测开路电压，有时需要长达 3 周的时间才能对电池进行鉴定。

We address these issues by using advanced Quantum Well Hall Effect (QWHE) sensors as a novel solution to enable a new paradigm in high resolution mapping of the magnetic fields inside the battery. Any flaws will manifest as magnetic “hot spots” that can very quickly check the state of health of the battery and therefore potentially lead to substantial savings in the testing of the batteries by reducing test times from tens of days to less than day or hours for defective batteries as the flaws can be “caught” very early in the qualification process.
我们通过使用先进的量子阱霍尔效应 （QWHE） 传感器作为一种新颖的解决方案来解决这些问题，以实现电池内部磁场高分辨率映射的新范式。任何缺陷都将表现为磁性“热点”，可以非常迅速地检查电池的健康状态，因此有可能通过将有缺陷电池的测试时间从几十天减少到不到一天或几小时，从而在电池测试中节省大量费用，因为缺陷可以在鉴定过程的早期就被“发现”。

The magnetic imaging of batteries is thus seen as critical for the structural health integrity and safety of these devices in a range of industries, from consumer electronics to electrical vehicles.

因此，电池磁成像在从消费电子产品到电动汽车等一系列行业中被视为这些设备结构健康完整性和安全性的关键。
