Abstract

See full text

An integrated DC/DC converter includes a first DC/DC converter, a second DC/DC converter, a first voltage sensor, a second voltage sensor, a first current sensor, a second current sensor, a third current sensor, and a controller. The first DC/DC converter has an input end and an output end. The input end of the first DC/DC converter is to be electrically connected to an output end of an electrochemical energy storage apparatus. The output end of the first DC/DC converter is to be electrically connected to an input end of an electrical load. The second DC/DC converter connects the first DC/DC converter in parallel.
