本发明公开了一种动力电池脉冲加热方法、装置、终端及存储介质，属于动力电池加热技术领域。The invention discloses a power battery pulse heating method, device, terminal and storage medium, and belongs to the technical field of power battery heating.
背景技术Background technique
随着能源问题的产生，国家对新能源产业的大力支持，锂离子电池由于其能量密度大，自放电率低和无记忆效应等优点，成为重要的储能元件，在新能源电站，电动汽车等领域得到了广泛应用。With the emergence of energy problems and the country's strong support for the new energy industry, lithium-ion batteries have become an important energy storage component due to their high energy density, low self-discharge rate and no memory effect. In new energy power stations, electric vehicles It has been widely used in other fields.
新能源汽车的快速发展下，用户对冬季续航里程低的抱怨不断增长。由于锂电池内部的结构及电化学性质，在低温下锂电池的充放电性能存在较大问题。由于低温下活性物质的活性降低，内部的扩散速率减小，锂离子电池内部阻抗在低温下大幅增加，输出功率减小，同时可用的电池容量也相应的减小。同时在低温下使用锂电池存在负极析锂等问题，使得锂电池的低温加热成为必要。而采用外部加热的方式存在温度分布不均匀的问题。With the rapid development of new energy vehicles, users’ complaints about low cruising range in winter continue to grow. Due to the internal structure and electrochemical properties of lithium batteries, there are major problems with the charge and discharge performance of lithium batteries at low temperatures. Since the activity of active materials decreases at low temperatures and the internal diffusion rate decreases, the internal impedance of lithium-ion batteries increases significantly at low temperatures, the output power decreases, and the available battery capacity also decreases accordingly. At the same time, there are problems such as lithium precipitation in the negative electrode when using lithium batteries at low temperatures, making low-temperature heating of lithium batteries necessary. The use of external heating has the problem of uneven temperature distribution.
目前，第一种较为成熟的技术是PTC加热，其通过高电阻的导体配合足够大的电流产生高温，高温在加热电池包管路中的冷却液实现电池升温，同时能够给空调系统的交换器加热，简单可靠但能效低，耗能比较大。第二种较为成熟的技术是热泵加热，其利用压缩机“反向运转”，使R134a制冷剂吸收热能快速沸腾产热，给车内空气或电池组加热。优点是具有超高能效，但是超高能效以室外温度高为前提，当室外温度较低(-30～-10℃) 时，加热不理想。第三种较为成熟的技术是脉冲自加热，其用一种脉冲加热的方法，实现电池的快速加热。相比较前面两种技术，加热效率更高，但脉冲自加热没有进行提前干预控制，当电池温度较低时且其充电能力不足，直接限制了电动汽车使用的便利性，尤其在寒冷的冬季，电动汽车的严重影响了用户感受。At present, the first relatively mature technology is PTC heating, which uses high-resistance conductors and a large enough current to generate high temperatures. The high temperature heats the coolant in the battery pack pipeline to heat up the battery, and can also heat the exchanger of the air conditioning system. , simple and reliable but with low energy efficiency and relatively large energy consumption. The second more mature technology is heat pump heating, which uses the compressor to "reverse operation" so that the R134a refrigerant absorbs heat energy and boils quickly to generate heat, heating the air in the car or the battery pack. The advantage is that it has ultra-high energy efficiency, but ultra-high energy efficiency is based on high outdoor temperature. When the outdoor temperature is low (-30~-10℃) When, the heating is not ideal. The third more mature technology is pulse self-heating, which uses a pulse heating method to achieve rapid heating of the battery. Compared with the previous two technologies, the heating efficiency is higher, but pulse self-heating does not carry out early intervention control. When the battery temperature is low and its charging capacity is insufficient, it directly limits the convenience of using electric vehicles, especially in cold winter. Electric vehicles have seriously affected user experience.
