Background
The current development direction of energy storage lithium ion batteries is to move to the fields of higher energy density, longer cycle life, lighter, thinner, safer and the like, namely, the combination of the energy storage lithium ion batteries is required to have larger capacity to support the product to run for a longer time, and meanwhile, the battery charging time is required to be shorter, so that the charging current with larger multiplying power is required to be satisfied. The satisfaction of these conditions requires that the battery satisfy a high-rate charge and discharge performance in addition to the use of a multi-string and multi-parallel battery module. Regardless of the serial-parallel mode of parallel combination of the battery units or the high-rate charge and discharge of the battery, the heat dissipation problem of the battery is aggravated, so that the central temperature of the battery is abnormal. And too high battery temperature often leads to the battery electrochemistry system unstability in turn, appears the battery short circuit or fires burning, causes the safety problem.
At present, the rapid development of electric power energy storage, especially for a peak-shaving frequency-modulation energy storage battery system, requires not only the charge and discharge with the change of multiplying power, but also the greatly increased charge and discharge frequency, and provides higher requirements for the cycle life and the thermal management of a lithium battery.
At present, the battery pack is cooled mainly by air cooling, liquid cooling and phase change. Air cooling is the most common heat dissipation method, and generally, a cooling fan is installed to force air to carry out convection cooling, but the battery avoids low heat exchange coefficient with air, so the cooling and heat dissipation effect is poor, and meanwhile, an air cooling system adopting an air conditioning system component is easy to cause dew accumulation, and the use safety of the battery system is reduced. The phase-change material cooling is to cool or heat the battery by utilizing the stored or released heat when the material is subjected to phase change, although the method has a good heat dissipation effect, the phase-change material heat dissipation technology is not mature, the structure is complex, the cost is high, and the maintenance is inconvenient. The liquid cooling utilizes liquid with relatively high heat conductivity to directly or indirectly contact the battery for heat dissipation, the main method is to arrange a jacket around the module or arrange a heat transfer pipe between the modules, the liquid cooling system in the field of energy storage at present only needs to adopt a standard liquid cooling plug box similar to a passenger car with large electric quantity, the process is complex, most structural parts are grinding tool machined parts, the cost is high, and secondly, the box body is large in size and convenient to install and maintain in a narrow space of a container.
Therefore, we propose a liquid-cooled CTR energy storage battery system.
