The invention belongs to the technical field of new energy battery charging, and particularly relates to a new energy equalization instrument based on high-precision current and voltage detection, which is applied to a new energy automobile battery and comprises a host, a plurality of current and voltage detection charging assemblies and a control module, the plurality of current and voltage detection charging assemblies are connected with the host through first charging wires, the plurality of current and voltage detection charging assemblies are connected in parallel, and each current and voltage detection charging assembly is connected with a new energy automobile battery pack; the battery capacity of the battery cells can be detected when multiple battery cells in a single battery pack are charged, each battery cell is independently connected with one charging wire, and the battery cells can be automatically disconnected after being charged, so that the problem that part of the battery cells are overcharged is avoided, and the charging efficiency is improved. And when the temperature of a single battery cell is too high in the charging process, the power supply of the battery cell can be temporarily cut off, and the battery cell is automatically connected with a power supply for charging after the temperature is reduced.

    本发明属于新能源电池充电技术领域,具体涉及一种基于高精度检测电流电压的新能源均衡仪,应用于新能源汽车电池上,包括主机和电流电压检测充电组件和控制模块,电流电压检测充电组件有多个,多个电流电压检测充电组件均通过第一充电导线与主机连接,且若干个电流电压检测充电组件并联,且每个电流电压检测充电组件均连接一块新能源汽车电池组;本发明在对单个电池组内的多有电芯进行充电时能够检测电芯的电池容量,且每个电芯均单独连接有一充电导线,在单个电芯充电完成后能够自动断开,避免部分电芯出现过充的问题,且在单个电芯在充电过程中出现温度过高时还可暂时切断该电芯的供电,在其温度下降后自动连接电源充电。
