摘要:
Methods and apparatus for assembling a high voltage battery without exposing an operator to contacts having a voltage greater than a predetermined maximum are presented. A bus bar module has standard compartments equipped with integrated bus bars separated by break compartments without bus bars. The bus bar module can be coupled to a plurality of electrochemical cells to connect the cells in groups having a voltage less than a predetermined maximum Vmax. Compartment lids can be closed to prevent contact with connected posts. A separate non-integrated bus bar can be provided to a break compartment to connect a first group of cells with a second group of cells to form a series of connected cells that can provide a voltage greater than Vmax, to achieve a desired battery voltage. The bus bar module and methods of the invention can protect an operator during battery assembly or service.
摘要:
A vehicle power system includes an electrical power source, an electrical bus, and a contactor electrically connected with the electrical power source and electrical bus. The contactor includes first and second poles, dual plungers each operatively associated with one of the first and second poles, and an electromagnetic coil configured to cause at least one of the dual plungers to move if the coil is energized.

A vehicle may include an electric machine, a battery, a driver interface and one or more controllers. The one or more controllers may be configured to determine whether a battery imbalance condition exists, to cause an alert to be generated via the driver interface if a battery imbalance condition exists, to determine whether a response to the alert is received, and to cause the battery to be rebalanced in a single cycle if a response to the alert is received.
