摘要:
A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). Locations of collection, charging and distribution machines having available charged portable electrical energy storage devices are communicated to or acquired by a mobile device of a user or a navigation system of a user's vehicle. The locations are indicated on a graphical user interface on a map relative to the user's current location. The user may select particular locations on the map to reserve an available portable electrical energy storage device at a particular collection, charging and distribution machine location. The collection, charging and distribution machine locations displayed may also be based on a physical distance or driving time from the current location of the user mobile device or vehicle.

A vehicle is equipped with a battery, an electric motor configured so as to generate the driving force of the vehicle by use of the electric power stored in the battery, a charger configured so as to supply the electric power outputted from the power supply outside of the vehicle to the battery, and an ECU configured so as to control the state of charge of the battery when the battery is charged. The ECU calculates an index value indicating the state of charge of the battery, and sets the control range thereof. The ECU raises the upper limit of the index value so that the possible travel distance of the vehicle becomes not less than the target distance when predetermined conditions on degradation of the battery are satisfied.

A battery includes a battery monitoring system for performing a battery self test. The battery monitoring system is integrated into the battery and configured to monitor a first health of the battery. The battery monitoring system is configured to receive an input signal from a wired interface or a wireless interface. The input signal is configured to instruct the battery monitoring system to provide feedback regarding the first health of the battery and/or a second health of the battery monitoring system. The wired interface consists of a positive terminal and a negative terminal of the battery.

A charge point notification system includes a center device and an in-vehicle device disposed in an electric vehicle. The system provides a notification regarding a charge point based on a comparison between a required energy for traveling to a nearby charge point from a node that is close to the nearby charge point, and a remaining energy of the electric vehicle. The system does not generate a notification when the remaining energy is greater than the required energy by an amount greater than a first threshold. The system generates the notification, which is to be provided to the user via the in-vehicle device, when the remaining energy is greater than the required energy by an amount that is in between the first threshold and a second threshold, which is less than the first threshold, and when the nearby charge point exists within a first distance range from the electric vehicle.

A vehicle is provided with a battery, a motor configured to generate the driving force of the vehicle by using electric power stored in the battery, a charger configured to supply the battery with electric power outputted from a power source outside the vehicle, and an ECU configured to control the charged state of the battery when the battery is charged. The ECU calculates an index value indicating the charged state of the battery, and sets the control range of the index value. When a predetermined condition relating to the deterioration of the battery is satisfied, the ECU raises the upper limit value of the index value.

An apparatus comprises a power electronic energy conversion system comprising a first energy storage device configured to store DC energy and a first voltage converter configured to convert a second voltage from a remote power supply into a first charging voltage configured to charge the first energy storage device. The apparatus also includes a first controller configured to control the first voltage converter to convert the second voltage into the first charging voltage and to provide the first charging voltage to the first energy storage device during a charging mode of operation and communicate with a second controller located remotely from the power electronic energy conversion system to cause a second charging voltage to be provided to the first energy storage device during the charging mode of operation to rapidly charge the first energy storage device.
摘要:
Provided is a system method for periodically charging a sub-battery for an electric vehicle. In this method, an SOC self-discharge rate of the sub-battery is calculated. An LDC output voltage and a charging time of the sub-battery are set using the SOC self-discharge rate of the sub-battery and information received from an IBS. It is determined whether or not an SOC of a main battery is equal to or greater than a set value. Periodic charging is performed on the sub-battery through an operation of an LDC when the SOC of the main battery is equal to or greater than the set value.
摘要:
An estimation apparatus of estimating a deterioration state of a secondary battery has a current sensor measuring an electric current of the secondary battery, a current estimating section estimating the electric current of the secondary battery by using a battery model, and a deterioration estimating section estimating a second deterioration component produced in association with a salt concentration imbalance in the secondary battery. The deterioration estimating section estimates the second deterioration component by using the measured current obtained from the current sensor, the estimated current obtained from the current estimating section, and a first deterioration component produced in association with wear of the secondary battery. The deterioration estimating section corrects the estimated current by using a ratio between a resistance change rate of the secondary battery when the second deterioration component is eliminated and a resistance change rate during charge and discharge of the secondary battery.
摘要:
A vehicle has an ECU, a battery being chargeable with off-board electricity and a motor driven by electric power of the battery. The ECU has a microcomputer to receive an operation time each time a user sets the ECU in an operation state, prepare a frequency of operation times for each time zone, and set a time of the time zone corresponding to the high frequency as a charging end target time. When the microcomputer receives a signal from an onboard charger connected with an off-board power source, the microcomputer sets a charging schedule such that the battery charged by the charger according to the schedule is set in a fully-charged state at the charging end target time. The microcomputer controls the charger to charge the battery according to the schedule and to set the battery in the fully-charged state at the charging end target time.
