Problems solved by technology

However, as the number of battery strings increases, so does the system complexity
For example, due to the input capacitance of the load, the initial connection of the battery to the DC bus can generate severe inrush currents that can damage the vehicle's electrical components

Abstract

A method is disclosed for connecting a plurality of battery strings to a direct-current (DC) bus. The method may include sorting the plurality of battery strings in an order based on respective output voltage values of the battery strings. The sorted plurality of battery strings may include, in the order, at least a first battery string and a second battery string. The method may also include connecting the first battery string to a pre-charge circuit. The method may further include pre-charging the DC bus using the first battery string and the pre-charge circuit. The method may further include connecting the first battery string to the DC bus. The method may further include connecting the second battery string to the DC bus.

Description

technical field [0001] The present disclosure generally relates to systems and methods for connecting battery strings to a direct current (DC) bus, and more particularly, to a DC bus for connecting multiple battery strings to a vehicle when the multiple battery strings have different output voltages systems and methods. Background technique [0002] A battery powered vehicle, such as an electric vehicle or a hybrid vehicle, may contain one or more high voltage battery packs connected to a DC bus. A high voltage battery pack can be used as the vehicle's primary power source to drive various primary loads (eg, traction motors) and various auxiliary loads (eg, HVAC, lighting, pumps, etc.). To improve system stability and availability, the high voltage battery pack can be configured as multiple battery strings connected in parallel to the DC bus. However, as the number of battery strings increases, so does the system complexity. For example, due to the input capacitance of th...
