Abstract: A circuit can include a CAN bus and multiple nodes. The multiple nodes can reboot at the same time so that a Time 0 is set at boot for each node. Each node can store an ID node and determine from its ID node one time slot of a plurality of periodic time slots starting from Time 0 in which to transmit on the CAN bus. Each node can transmit messages on the CAN bus in its determined time slot subsequent to Time 0.

Abstract: Embodiments of the present disclosure are directed to providing temporary, additional cooling to one or more elements of the vehicle on an as needed basis, e.g., under extreme conditions, when additional cooling is required or predicted to be needed, etc. According to one embodiment, the RC can be “overclocked” or “supercharged” to provide short-term, high output cooling performance under such conditions. For example, if the cooling system is a 10 kW system, it is increased to 15 kW for a short time period by increasing the electrical current and/or frequency to increase the torque and/or speed of the motor driving the RC. According to one embodiment, the cooling system can also be adapted to more effectively utilize the available cooling capacity, either the standard capacity to temporarily increased capacity, by directing the air or liquid coolant to one or more components in need of extra cooling.

Abstract: An electrical system includes a voltage bus, battery pack, power inverter module (PIM), electric machine, first contactor, and controller. The PIM is connected to the battery pack and has a capacitor, voltage sensor, and semiconductor switches. The electric machine having phase legs with a corresponding phase winding and resistive path. The first contactor connects the PIM to a positive rail of the bus. The controller opens the first contactor in response to a power-off event, commands a discharge of the capacitor through the resistive paths, diagnoses a state of health (SOH) of the first contactor using a first threshold decay rate of the capacitor output voltage upon opening the first contactor, and executes a control action with respect to the electrical system using the diagnosed SOH. The three possible SOH are unhealthy/hard-welded contactor, unhealthy/soft-welded contactor, and healthy/normally-functioning contactor condition. A vehicle and method are also disclosed.

Abstract: A method is provided for optimizing the operating lifetime of an energy storage system including a battery pack with a plurality of battery cells. The method includes: measuring the temperature of the battery pack by means of a sensor unit; and measuring at least one further parameter representing an indication of the operating lifetime of the battery pack. Furthermore, the method includes the steps of: detecting whether the parameter reaches a predetermined threshold value indicating that the battery pack is in a condition close to an end of its expected operating lifetime; and, in the event that the threshold value is reached, initiating heating of the battery pack, thereby increasing the temperature of the battery pack to a predetermined value so as to prolong the operating lifetime of the battery pack. A system for optimizing the operating lifetime of an energy storage system is also provided.

Abstract: A battery module includes a housing configured to hold prismatic battery cells within a space defined by four interior walls of the housing. The housing includes a first interior wall that includes partitions extending upwards from a bottom of the housing and a second interior wall that includes partitions extending upwards from the bottom of the housing. The first interior wall faces opposite the second interior wall. The partitions disposed on the first interior wall and the partitions disposed on the second interior wall define slots between adjacent partitions, where each of the slots increases in width between the adjacent partitions from the bottom of the housing upwards. Each of the slots is configured to retain one of the prismatic battery cells.

Abstract: Systems and methods for sensing internal states of vehicle batteries are described. From this internal state information, various physical characteristics of the battery can be measured, calculated or inferred. A vehicle can include an electric motor, a battery to store electrical energy for the electric motor, and a sensor connected to the battery to sense a battery state, to receive an input signal, and to wirelessly transmit an output signal indicating the battery state. The sensor may be passive and built into the structure of the battery. The sensor can be a surface wave acoustic sensor with a magnetic field sensor, which can be a magnetoimpedance sensing device and a temperature sensor.

Abstract: Methods, devices, and systems are provided that track details of power transfers made between power sources and electric vehicles. The power tracking system monitors the source of charges received, how much charge was provided, rates billed for the charging service and other information related to a charging transaction. The tracked power consumption may be used by the power tracking system server to anticipate future charging times, preferences, or locations, and even determine driving habits, and demand for charging in a region or area.
