Description

Super capacitor communication controller

Technical Field

The utility model relates to a new forms of energy controlgear technical field especially relates to a super capacitor communication controller.

Background

In order to cope with the current environment and energy crisis, new energy automobiles are vigorously developed to become a consensus of the international society, and electric automobiles also become a necessary trend for the development of the automobile industry in the future. Among them, the energy storage device of the electric vehicle becomes one of the important factors for the development of new energy technology. The super capacitor serving as a novel energy storage device can be used in extremely-low-temperature and other extremely-severe environments, has no environmental pollution, has the characteristics of safety, reliability, wide application range, greenness, environmental friendliness, easiness in maintenance and the like, and is a breakthrough component for improving and solving the application of electric energy and power.

The single working voltage of the super capacitor is not high, mostly between 1V and 4V, and in practical application, a plurality of single capacitors are generally required to be connected in series for use. When the capacitors are connected in series, because parameters (such as capacitance, ESR, leakage current and the like) of each single capacitor have certain difference, voltage at two ends of each single capacitor is unbalanced easily in a heavy current discharging process, partial capacitors are over-charged and over-discharged, and the service life of the capacitors and the reliability of the whole circuit are influenced. Although the difference of the parameters of the super capacitor has small influence on the voltage sharing in the initial stage of application, the influence on the voltage sharing of the super capacitor is larger and larger as the discrete type of the parameters becomes larger in the middle and later stages of the use process, and finally the service life of the super capacitor is shortened sharply. Meanwhile, if the charging current of the capacitor is too large, the working temperature is too high, the voltage of the single body is too high, and the like, safety accidents such as combustion, explosion and the like are easy to happen. In order to avoid the above situations, the conventional method is to uniformly manage the super capacitor by using a super capacitor communication controller.

At present, the following problems exist in the common super capacitor communication controller: 1. the number of communication interfaces is small, the communication protocol is specified and can not be flexibly configured, and the flexibility is poor; 2. the signal input and output interfaces are few, the types are not rich enough, the access to various signals is inconvenient, and the adaptability is poor. In summary, the current super capacitor communication controller has poor adaptability and flexibility, and brings great inconvenience to the application and maintenance of the system integrator under the requirements of different application environment items.

To this end, the applicant has sought, through useful research and research, a solution to the above-mentioned problems, in the context of which the technical solutions to be described below have been made.
