All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
It should be noted that, in the embodiments of the present application, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration.

Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.
It should be noted that, the architecture described in the embodiments of the present application is for more clearly describing the technical solution of the embodiments of the present application, and does not constitute a limitation on the technical solution provided by the embodiments of the present application, and those skilled in the art can know that, along with the evolution of the communication technology, the technical solution provided by the embodiments of the present application is equally applicable to similar technical problems.

The storage battery is widely applied to industries such as industrial production, traffic, communication and the like, is generally used as a backup power supply, and is used for emergency when a main power supply or power generation equipment fails. The storage battery is used as a standby direct current power supply of the communication system, and plays a significant role in reliably supplying power to the communication power supply. When an alternating current power failure or a rectification module failure occurs, the control system can be automatically switched to a storage battery to supply power, and direct current power is directly supplied to the communication equipment, so that the communication network can still normally operate. The capacity, internal resistance and service life of the battery can be correspondingly changed along with the change of temperature. The temperature measurement is mainly to check whether the temperature is abnormal or not, and during the charge and discharge process of the battery, joule heat is generated by electrochemical reaction inside the lead-acid battery to cause electricity. The normal rated capacity of a battery refers to the result measured at a specific discharge rate at 25 degrees celsius before the battery leaves the factory. Changes in battery temperature can have a significant impact on battery performance. For example, when the temperature of the storage battery increases, the activity and diffusion speed of the battery polar plate and the electrolyte increase, the internal resistance of the battery decreases, the SOC of the battery also increases, the concentration of the electrolyte increases, and the grid corrosion increases. When the temperature of the storage battery exceeds a limit, the deformation of the positive plate and the negative plate is easy to cause, the self-discharge phenomenon can occur in the storage battery, and even the explosion of the storage battery can be caused when the temperature is serious. When the temperature of the storage battery is low, the activity of the electrolyte is reduced, the conductivity of the battery is reduced, the impedance is increased, and the output power of the storage battery is reduced. The battery temperature is therefore an important measurement parameter for monitoring the battery.
However, in the single-bus multi-point temperature measurement circuit, the waveform distortion and timing dislocation of the transmission signal can be caused due to the charge and discharge effect caused by the distributed capacitance of the bus cable, so that the temperature of the storage battery cannot be accurately monitored.
In view of this, the present utility model provides a battery temperature monitoring system comprising: a charging circuit and a temperature acquisition circuit; the charging loop is connected with the temperature acquisition loop; the charging loop comprises a power supply and a storage battery pack connected with the power supply; the temperature acquisition loop comprises a plurality of temperature sensors connected in parallel and a switching tube connected with the temperature sensors.
