The invention relates to a power supply control system for switching battery configurations during driving. A power supply control system includes a battery system including N battery packs. The plurality of contactors selectively connect N battery packs of the battery system in a first configuration to supply a first voltage level, a second configuration to supply a second voltage level, and a disconnect configuration. The M power inverters connect the battery system to the M motors, respectively. The controller is configured to determine when to transition between the first configuration and the second configuration. The controller is configured to transition between a first configuration and a second configuration by causing one of a positive torque transient and a negative torque transient to be generated by at least one of the M electric machines; transitioning the battery system from one of the first configuration and the second configuration to a disconnected configuration; and transitioning from the disconnected configuration to the other of the first and second configurations.
本发明涉及用于在驾驶期间切换电池构型的电源控制系统。一种电源控制系统包括电池系统,该电池系统包括N个电池组。多个接触器以供应第一电压水平的第一构型、供应第二电压水平的第二构型、以及断连构型来选择性地连接电池系统的N个电池组。M个功率逆变器分别将电池系统连接到M个电机。控制器被构造成确定何时在第一构型和第二构型之间转变。控制器被构造成通过以下方式在第一构型和第二构型之间转变:引起由M个电机中的至少一个生成正扭矩瞬态和负扭矩瞬态中的一者;使电池系统从第一构型和第二构型中的一者转变到断连构型;以及从断连构型转变到第一构型和第二构型中的另一者。
