In some embodiments, the VCM performs other actions. The lithium-ion battery pack can be configured to control the following functions: 28V or other voltage, and connects the power of the first voltage to an electric motor. The system operates to supply electric motors for driving utility vehicles. The vehicle 12 may include a second battery having a lower voltage than the first voltage, for example as part of a lithium ion battery pack. The DC / DC converter may be configured to output power at a voltage. In the embodiment, the second voltage is 12V. VCM is connected to a DC / DC converter. and configured to receive power from the DC / DC converter and operate at a second voltage. and is configured to control at least some operation of the utility vehicle 12.

The charger is connected to the lithium-ion battery pack under the control of the VCM. The device is configured to charge an UM-ion battery pack.
[0021] In electric utility vehicles, the VCM is a hardware-based discrete input. The charger is configured to detect the connection of the charger via the The VCM communicates with the motor controller to, for example, prevent vehicle motion while charging. The VCM detects that the vehicle is in charging mode and turns off power to the controller logic board. The battery control module is configured to notify the battery control module on a separate data bus of the charging mode. When the battery control module is in the Based on the algorithm, the device broadcasts the requested charging current value on the data bus. The VCM is a battery, e.g., a lithium-ion battery pack, in one form. The lithium ion battery pack includes one or more lithium ion battery cells. The charger outputs the requested charging current value via the data bus to charge the Issues a command to turn on the charger. The requested charging current value can be, for example, one or may vary at different points or times throughout the charging cycle based on further parameters. For example, a requested magnitude of current can be calculated using stored equations and stored rules. The power supply to the VCM or the charger is based on at least one of the lookup tables. The requested current can be based on one or more of several parameters. Also, for example, temperature such as battery temperature, how fully charged the battery pack is, The limiting current may be set based on the desired battery life or The battery life is determined based on charge cycle life and / or other parameters. When the charging current value of the module changes, the new or changed current value is broadcast on the data bus. The charger is broadcast and the VCM does not allow new charges to be applied until the VCM determines that charging is complete. The charger may be commanded to output a new or changed charging current value.
[0022] The VCM may be, for example, disposed as part of or considered as part of the motor controller. The present invention is configured to perform vehicle power bus pre-charging such that a capacitor back that can be used for charging the vehicle power bus is pre-charged.

For example, in some embodiments, the lithium ion battery pack is , which is used to precharge the motor controller's capacitor bank. After the contactors are disconnected, they are inspected to see if they have closed unintentionally, e.g., welded closed. For example, in regard to Figure 4, the main contactor is connected to the lithium-ion battery. This is checked by subtracting the Vout of the pack from the Vcap of the capacitor bank. If the delta or difference is greater than a threshold, e.g., a predetermined threshold, then the contactor is not welded closed. If Δ is not greater than the threshold, the weld check has failed, which means that the main This means that the contactor is welded. Next, check contactor B. The threshold is calculated by subtracting Vm from Vcap. This delta or difference is then equal to a threshold, e.g., a predetermined threshold. If Δ is not greater than the threshold, the contactor is not welded closed. The contactor check has failed, meaning that contactor B is welded.

The force may be used, for example and without limitation, to contact the contactors A, B and main contacts described above. Control alternative and / or additional components such as the BCM and MCU. It can be either directly or indirectly through other subsystems. In some operations, the VCM may be used to shut down the main power output, for example, when the main power output is disconnected or when a welded When the check is complete, the main DC / DC converter is disabled. The VCM can output commands to control the contactors and converters to and / or additionally, after the main power output of the pack is disconnected via a contactor, Turn on the main DC / DC converter to discharge the HV capacitor in the MCU. In some configurations, the VCM is driven by the MCU. The wheel speed can be monitored via an encoder that operates the If motion is detected while the motor is off, the VCM will operate the MCU in regenerative braking mode. It can output a command to control all contactors to the closed position so that Any control mode of the VCM requires direct I / O (separate and dedicated discrete or can occur either on a digital signal (analog signal) or on the in-vehicle network communication bus.
