摘要： Methods and systems provide for the manufacture of a cylindrical battery cell case that is changed from steel (or nickel-plated steel) to aluminum. With this change, spot welding the copper tab from the anode to the aluminum case will result in the copper and aluminum corroding over time—leading to early battery failure. To manufacture the battery with the aluminum case, one or more manufacturing changes are made including one or more of: 1. changing the polarity of the battery to spot weld the copper tab to a steel top of the battery; 2. coating the copper tab with a second material to prevent corrosion; and/or, 3. use a different welding method (e.g., a friction stir weld) to fuse the copper tab to the aluminum case.

摘要： A power module for a vehicle includes a first bidirectional voltage converter to convert a first voltage to a second voltage and convert the second voltage back to the first voltage. The power module includes a second bidirectional voltage converter to convert the first voltage to a third voltage and convert the third voltage back to the first voltage. The power module includes a first battery coupled to the first bidirectional voltage converter to receive the second voltage, and a second battery coupled to the second bidirectional voltage converter to receive the third voltage. The power module includes a controller to control the first and second bidirectional voltage converters and the first and second batteries. The first voltage is for supplying power to a powertrain of the vehicle. The second voltage and the third voltage are for supplying power to the first and second batteries, respectively.

摘要： A device for charging an energy storage device includes a controller to initiate a charging operation for the energy storage device and control, during a first stage of the charging operation, a thermal control system to direct a first volume of the thermal mass along a first flow path to heat the energy storage device to a first desired temperature. The controller controls, during a second stage of the charging operation, the thermal control system to direct a second volume of the thermal mass along a second flow path to cool the energy storage device from the first desired temperature towards a second desired temperature.

摘要： Methods and systems are provided for managing multi-battery systems, such as those utilized in an electric vehicle. Multi-battery systems comprise batteries providing power in parallel, thereby making each battery available to the vehicle and avoiding the weight of transporting a backup battery. The methods and systems provided allow for a fault in one battery, in a parallel configuration with at least one other battery, to be detected and managed.

摘要： 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.

摘要： Embodiments of the present disclosure are directed to dynamically and automatically adjusting a standard regenerative braking intensity. Roadway data, data from one or more sensors of the vehicle and data comprising parameter values for operating states of the vehicle regarding a roadway from a route being navigated by the vehicle are received by a processor of a control system of the vehicle. Standard regenerative braking intensity values based on a vehicle's acceleration is retrieved from memory. Adjusted regenerative braking intensity values are calculated based on at least one of the roadway data, the sensor data and the parameter values of the operating states of the vehicle and the standard regenerative braking intensity values. The adjusted regenerative braking intensity values are transmitted to the control system and an acceleration or deacceleration amount is applied to the vehicle based on the adjusted regenerative braking intensity values.
