In terms of the safety of energy storage batteries and power batteries, temperature acquisition and control are crucial. A temperature sensor with excellent consistency can effectively monitor battery temperature changes and prevent thermal runaway in advance, causing serious attenuation of lithium battery energy and power. This ensures the safety of energy storage batteries, power batteries and the stability of new energy.
The “uncrowned king” in the field of temperature sensors for energy storage batteries and power batteries has reported another technical success. Invented a temperature sensor that uses ultra-small multi-point temperature measurement inside the battery, the first in the world!
传统热敏电阻的一步燃烧电气极化过程. 整个产品的性能受到银糊和热电阻车身材料的匹配的影响. 特别是对于SMD和插件NTC, 焊接全部焊接. 这个过程导致缺陷,例如去贬值, 饮食, 和瓷器爆炸. 同时, 由于焊接材料的温度抗性差异, 热膨胀系数的差异, 以及玻璃相和瓷器体之间的化学键差异. 以及外部生产过程卫生和其他条件的影响, 热敏电阻的总温度电阻水平不高. 而且, 此电极 + 铅线焊接过程限制了热敏电阻的大小. The smallest size available is Japan’s Shibaura diameter of 0.45mm.
YAXUN, which has provided external temperature measurement services for hundreds of energy storage and power batteries, has already realized in 2022 that “the problem of internal battery temperature measurement is still a difficult problem for the industry!”
According to feedback from many battery technicians, the current temperature of batteries is measured by transmitting the internal temperature of the battery through the battery poles.
Once the heat transfer speed is slow and the true temperature of the battery core cannot be quickly fed back, the battery will burn out and the temperature has not yet been fed back. 第二, the specific location cannot be measured, so it is blind. 如果温度上升点恰好位于极点的最远点, 可能发生热失控. 第三, 无法测量区域,整个电池芯无法测量. 4. 耐腐蚀不够. 传统传感器需要铜线才能绘制信号, 需要绝缘, 并需要反腐败保护.
为了测量电池的内部温度, 温度传感器必须是超小的, 必须有多个点, 并且必须同时满足其他多种条件!
在 2023, 经过将近一年,超过 3,000 研究,开发和测试的迭代, 在秋天的9月, 最后, 中国首个用于内部电池测量的超小型多点温度传感器!
我们发明了电池内使用的超小多点温度传感器, 这是中国的第一个. 1. 不需要电化处理, 铅线直接与瓷器体形成欧姆接触.
2. 最小直径可以为0.2mm, 甚至更小.
3. 抗温度可以达到-100〜+500度, 响应速度是 50 毫秒.
第四, 也可以实现“梯子结构”. 所有NTC都悬挂在两个并行或系列的导体上. 由于它们的尺寸很小, 它们可以被涂成磁带或床单. 实现区域温度测量. 该地区任何地方的任何温度都可以反映在传感器上.
据报道,该技术具有五个明显的优势: 它可以执行点测量, 线测量, 和表面测量, 并实现多维空间测量. 传感器体非常小,热磁滞很小. 传感器处于膜形状,以最大化其与离子膜的接近性,并且快速. 金属铅线是铂金属丝, 具有良好的耐腐蚀性. 膜材料也具有耐腐蚀性 (聚酰亚胺或PE, pp, ETC。), 耐温, 耐腐蚀, 和抗拉力.
