Problems solved by technology

[0004] At present, there is no special battery used in photovoltaic systems, so some defects of lead-acid batteries, such as poor resistance to overcharge and overdischarge, are more obvious in photovoltaic power generation systems
Due to the strong randomness and poor stability of the photovoltaic power generation system, it is difficult to ensure that the battery is charged and discharged regularly

Description

technical field [0001] The invention relates to the technical field of storage battery monitoring, in particular to an online monitoring system for charging and discharging of storage batteries. Background technique [0002] Environmental pollution and energy crisis have become two major problems in current development. Therefore, vehicle electrification technology has been extensively studied due to its unique advantages such as green environmental protection, energy saving and emission reduction. As the key to vehicle electrification technology, battery performance has a major impact on the safety and development prospects of electric vehicles. There are slight differences depending on the type of electric vehicle. In a pure electric vehicle equipped only with a battery, the role of the battery is the only source of power for the vehicle's drive system. In a hybrid vehicle equipped with a traditional engine (or fuel cell) and battery, the battery can not only play the ro...
