The invention discloses a parallel connection method for multiple loops of a direct-current high-voltage system of new energy vehicles and ships. The multiple loops of the direct-current high-voltagesystem are involved in the method and are composed of a first battery pack and a second battery pack. According to the invention, two groups of battery systems can be effectively connected in parallelinto a whole to provide energy for a load, so the influence of voltage difference between the two groups of battery systems is effectively solved, and meanwhile, when one group of battery pack has aserious fault and needs to be maintained, recovery can be conveniently conducted without worrying about the influence of a voltage difference; the charging circuits of the first battery pack and the second battery pack are connected in parallel through a high-power conduction diode D3 and a high-power conduction diode D4, so the two battery packs form a whole to be charged by a charger, and the problem that an existing system needs two independent charging interfaces to respectively charge battery systems is solved; and the charging system is simplified, personnel on duty is not needed, and acharging gun does not need to be pulled out manually to charge another group of batteries after charging of one group of batteries is completed.
本发明公开了一种新能源车船直流高压系统多回路并接方法,包括直流高压系统多回路,直流高压系统多回路包括第一电池组与第二电池组;通过将两组电池系统能有效并接为一个整体为负载提供能源,有效解决了两组电池系统之间压差的影响,同时当其中一组电池组出现严重故障需要维修时,方便的恢复且无需担忧压差的影响;采用大功率导通二极管D3与二极管D4把第一电池组与第二电池组的充电回路并接起来,让两个电池组形成一个整体接受充电机的充电,解决现有系统需要两个独立的充电接口来分别为电池系统充电的问题。让充电系统简单化,并且无需人员值守,无需等待一组电池充电完成之后,需要人工拔充电枪,再给另外一组电池充电。
