Description

technical field [0001] The invention relates to the field of vehicle-mounted nickel-hydrogen battery charging, in particular to a voltage-controlled current source controller. Background technique [0002] The application of the Ni-MH battery charging circuit in the vehicle requires many control parameters, one of which is the charging current of the Ni-MH battery. Currently commonly used Ni-MH battery charging circuits are as follows. [0003] 1. Dedicated battery charging circuit. At present, the dedicated battery charging circuits on the market are mainly dedicated battery charging ICs, but most of these battery charging ICs are aimed at normal temperature charging circuits. As the temperature continues to change, the battery charging IC is greatly affected by the temperature. Under the influence of temperature, the charging performance of the battery charging IC will be greatly limited, so that it is difficult for this type of battery charging IC to adapt to the comple...
