一种用于电动汽车的充电计费装置及其实现方法A charging and billing device for electric vehicles and its implementation method

技术领域：Technical field:

本发明涉及电力技术领域，具体涉及一种用于电动汽车的充电计费装置及其实现方法。The invention relates to the field of electric power technology, in particular to a charging and billing device for electric vehicles and an implementation method thereof.

背景技术：Background technique:

随着电力自动化程度不断提升，提出了用电设施配套安全可靠的用电消费方法，保证对用户消费的准确性和收费的可信性的要求。目前用于电动汽车上的已有的实时用电收费方法普遍采用了依靠计量设备和通用控制器共同计算消费信息的方法。这种方法的弊端是消费信息的处理归于整个程序流程的一部分，准确性和可靠性无法保障，基本属于一种“估值”，极不合理，不利于节能环保。With the continuous improvement of the degree of power automation, a safe and reliable power consumption method for power facilities is proposed to ensure the accuracy of user consumption and the credibility of charging. Currently, existing real-time electricity charging methods for electric vehicles generally adopt the method of jointly calculating consumption information by relying on metering equipment and a general controller. The disadvantage of this method is that the processing of consumption information is a part of the entire program flow, and the accuracy and reliability cannot be guaranteed. It basically belongs to a kind of "valuation", which is extremely unreasonable and not conducive to energy conservation and environmental protection.
