The problem of monitoring and balancing of vehicle batteries

The use of electrochemical energy storage units is becoming more common, and they are subject to new requirements for increasing the time of electrical supply for power equipment. In some cases, batteries serve as the main electric power unit working under reserved electric load and on the electric drive of the vehicle. The article discusses the features of using batteries as a part of electrical equipment for the agricultural vehicles. When creating high-capicity batteries trhrough connecting some batteries in series and parallel circuits, there are a number of features caused by variations of the parameters of the elements. Materials and Methods The object of research is methods of monitoring and balancing touch batteries are connected in series and there is no possibility or desirability of their disconnection for individual balancing. In the development of methods and devices used in general engineering approaches to the development of technical devices. Results It is necessary to find the causes affecting the energy characteristics and service life of the battery to increase it. During research we have found a need for monitoring and control of battery status, which allow solving the problems of divergence of containers, the internal resistance and leakage of individual batteries. Temperature of the battery is an important indicator to control it. Balancing the battery system and monitoring systems are needed to provide a uniform charge of individual cells, regardless of the variation parameters. Discussion and Conclusions There are different variants of balancing systems, each of which has its own advantages and disadvantages. The article gives examples of the construction of five alignment systems stress on the individual cells of the battery. The criteria for selection for the current passive balancing method using shunt resistors, and are a diagram of an improved passive way of balancing. Considered and the basic advantages and disadvantages of active methods of balancing. A comparative analysis of methods of balancing the cell voltage batteries found ways to balance the capacitor problems whose solution will provide an optimal method for balancing electrical mobile agricultural machinery.
