System and method for predictive control of an energy storage system for a vehicle
A system and method for management of an energy storage system for a vehicle is disclosed. The energy storage system may comprise a battery system for a vehicle such as an electric vehicle or hybrid-electric vehicle. Vehicles may be in a group of fleet. The management system may be configured to use data and information available from data sources over a network or by instrumentation/sensors for vehicle systems. Data and information could be used in a system to manage the configuration and operation of the energy storage system and components, manage/control inventory and use/life-cycle of components, and/or aggregated/analyzed in analytics function for systems and components. Predictive control of the battery system may be implemented through a management system using data sources external to the vehicle. Inventive concepts and features of the systems and methods are indicated in the specification and FIGURES.
CONTROLLING BATTERIES FOR ELECTRIC BUS
An onboard charging system for an electric vehicle is configured to communicate with a power supply through exchange of control signals on a power supply line by modulating a charging current being supplied to the charging system. The charging system is capable of communicating fault and battery parameter data to the power supply, as well as a requested charging current used to regulate the power supply output. The power supply may convert high voltage AC power into a controllable DC output supplied directly to the electric vehicle, thereby providing a convenient means for the vehicle to initiate charging during operations. Connection between the electric vehicle and the power supply may be effected using an extendible and retractable electrical connection, such as a mechanical pantograph.

Data acquisition for operation of a vehicle
A vehicle has independent electric traction system (ETS) and internal combustion engine (ICE). A system controller, a data acquisition system, and a GPS system are added to the vehicle. A remote system has a data base of locations identifying emission non-attainment areas. The data acquisition system obtains the vehicle location along with parametric data related to operation of the vehicle. The remote system notifies the vehicle operator and the auxiliary control system of opportunities to obtain emission reduction credits in response to the vehicle location data and its operating status. The system controller or the operator switch between ICE operation and ETS operation in response to the vehicle location, emission reduction credit process, and parametric measurements of the vehicle operation to achieve an emissions credit result while optimizing fuel for the ICE and stored electrical potential energy for the ETS.

ELECTRIC VEHICLE (EV) CHARGE LOCATION NOTIFICATIONS AND PARKING SPOT USE AFTER CHARGING IS COMPLETE
A computer implemented method is provided. The method includes detecting, by a computer of a charging unit (CU), a connection of a charging connector of the CU to a vehicle charge port of an electric vehicle (EV). The detecting of the connection includes processing a data exchange between electronics of the EV and the computer of the CU. The method includes receiving, by the computer of the CU, charge status of the EV while the charging connector is connected to the CU. The received charge status of the EV changes as charge is provided from the CU to a battery of the EV. The method includes sending a notification by server to a user account that was used to obtain charge for the EV at the CU. The notification provides data for a graphical user interface that shows the charge status of the EV. The method includes receiving instructions from a device associated with the user account, to make payment of a fee or receive a fee charge, to instruct the CU to indicate an in progress or in-use state even when the EV is at a full level of charge while the EV is occupying the CU and is preventing others from access to the CU that is provided for public use of users with user accounts. The method includes sending data by the server to the computer of the CU to display an in progress or in-use state, wherein the server communicates over the internet with the device.
Methods and Systems for Electric Vehicle (EV) Charge Units and Systems for Processing Connections to Charge units after Charging is Complete
Methods, systems, charge units, computer readable media, and combinations thereof are provided. One example method includes receiving data, at a server, indicative that a user account has accessed a charging unit for charging an electric vehicle. The charging unit has an indicator that identifies an active charging status while the electric vehicle is connected to the charging unit for charging a battery of the electric vehicle using the charging unit. The charging unit is configured to identify a complete charging status when the electric vehicle is finished charging said battery using the charging unit. The method includes receiving data, at the server, indicative of a status of charge of the electric vehicle during the charging. Sending a notification to a device having access to the user account, regarding said status of charge during the charging of the electric vehicle. The notification identifies a current level of charge of the battery of the electric vehicle and optionally an estimate of a time remaining to finish charging the battery of the electric vehicle. The method includes receiving an instruction, from the device, to maintain the electric vehicle connected to the charging unit for a set period of time after the battery of the electric vehicle is finished charging. The server is configured to sends data to the charge unit to allow the electric vehicle to maintain connected to the charging unit even when the battery of electric vehicle has reached the complete charging status.
CHARGING STATION PROVIDING THERMAL CONDITIONING OF ELECTRIC VEHICLE DURING CHARGING SESSION
A vehicle includes an energy storage configured to store electric energy for at least propulsion of the vehicle, an energy storage thermal system configured to provide thermal conditioning of the energy storage, and a coupling configured to receive thermal conditioning of the energy storage from a thermal system external to the vehicle. The coupling provides thermal conditioning of the energy storage while charging when available from the thermal system external to the vehicle. The energy storage thermal system provides thermal conditioning of the energy storage while charging when the thermal system external to the vehicle is not available.
BATTERY DEGRADATION ACCUMULATION METHODS
A vehicle includes a traction battery subject to alternating cycling and storage modes and a controller. The controller is programmed to calculate an accumulated degradation for the traction battery based on a degradation profile for the traction battery. The degradation profile defines degradation accumulated over time and may differ based on the mode and temperature. The initial degradation value includes the accumulated degradation for the present mode and at least a portion of the accumulated degradation for the other mode. Degradation is then accumulated according to the degradation profile starting from the initial degradation value. The amount of accumulated degradation from the other mode that is included may vary based on the mode and the accumulated degradation.
Dual battery fuel cell system
A dual-battery fuel cell system is provided, including two supplemental batteries, each battery supporting/supplementing operation of a fuel cell stack in the system. Driving conditions associated with a fuel cell vehicle can be obtained. Based on the driving conditions, power sources of the fuel cell vehicle to provide power to fuel cell vehicle system can be determined, the power sources comprising the fuel cell stack and the two supplemental batteries. Operating conditions of each of the power sources can be assessed, and one or more of the power sources can be controlled to deliver power to the fuel cell vehicle system based on the operating conditions of each of the power sources.
