摘要： An electrical storage system includes a main battery, an auxiliary battery, a bidirectional DC-DC converter and a controller. The bidirectional DC-DC converter is provided between the auxiliary battery and a power supply path from the main battery to a driving motor. The bidirectional DC-DC converter steps down an output voltage from the power supply path to the auxiliary battery, and steps up an output voltage from the auxiliary battery to the power supply path. The controller controls charging and discharging of the auxiliary battery. The controller, when an allowable output power of the main battery decreases and an electric power becomes insufficient for a required vehicle output, supplies an electric power to the power supply path by discharging the auxiliary battery by using the bidirectional DC-DC converter. The controller, when an allowable input power of the main battery decreases and a regenerated electric power generated by the driving motor is not entirely charged into the main battery, charges part of the regenerated electric power into the auxiliary battery by using the bidirectional DC-DC converter.

摘要： A battery system includes a chargeable and dischargeable secondary battery and a controller that estimates the deterioration state or the charge state of the secondary battery. When estimating the deterioration state or the charge state, the controller uses an average ion concentration between a positive electrode and a negative electrode. The average ion concentration varies depending on an electric current flowing through the secondary battery. The average ion concentration between the electrodes can be calculated with a computing expression that includes a surface pressure of the secondary battery as a variable. The surface pressure of the secondary battery can be detected by a pressure sensor. The surface pressure of the secondary battery can also be estimated from an electric current flowing through the secondary battery.

摘要： A ramp-equipped vehicle includes a ramp that is provided so as to be deployable from a side portion of a vehicle body to the outside of the vehicle body, a controller that controls the operation of deploying the ramp, and a sensor that senses moving bodies present in a certain area that is away from a ramp deployment area. The controller detects the moving bodies approaching the ramp deployment area and determines the moving velocities of the moving bodies based on the results of sensing by the sensor. The controller stops the operation of deploying the ramp when, after the start of the operation of deploying the ramp, it detects the approaching moving body having a moving velocity higher than or equal to a predetermined reference velocity with which the approaching moving bodies may reach the ramp deployment area during the operation of deploying the ramp.

摘要： A battery system includes a nickel hydride battery and an electronic control unit. The electronic control unit is configured to store data indicating a corresponding relationship between an elapsed time from start of use of the nickel hydride battery and a memory quantity. The data are data determined in a classified manner individually for each of conditions of use that are defined in such a manner as to include an open circuit voltage and a temperature. The electronic control unit is configured to sequentially calculate, with reference to the data, the memory quantity within a time when classification of the conditions of use does not change. The memory quantity is a quantity indicating an amount of change in voltage resulting from a memory effect. The electronic control unit is configured to estimate a current memory quantity of the nickel hydride battery by integrating the calculated memory quantity.

摘要： A system for determining fixation of a relay has an electricity storage device, an electrical apparatus, a relay, a first insulation resistor, a second insulation resistor, a detection circuit, and a controller. When the relay is controlled to OFF, the controller determines, based on the voltage value detected by the detection circuit (the detected voltage value), whether or not the relay is fixed. When the detected voltage value is a voltage value that is obtained by dividing the reference voltage value by a combined resistance value and the reference resistance value, the controller determines that the relay is fixed. When the detected voltage value is a voltage value that is obtained by dividing the reference voltage value by the first resistance value and the reference resistance value, the controller determines that the relay is not fixed.

摘要： In vehicle platooning, when road surface information is received from a preceding vehicle, an ECU determines whether a specific spot on a road included in the road surface information can be avoided. That is, the ECU determines whether avoidance control can be performed. When it is determined that the avoidance control can be performed, the ECU transmits the road surface information received from the preceding vehicle to a following vehicle, and performs the avoidance control to avoid the specific spot on the road. In contrast, when it is determined that the avoidance control cannot be performed, the ECU ends a process without performing the avoidance control.

The transformer includes a first coil and a second coil. The first coil is connected to the low-voltage battery. The second coil is connected to the high-voltage battery. An anode of the third diode is connected to one end of the first coil. One end of the reactor is connected to a cathode of the third diode, and the other end of the reactor is connected to a positive electrode terminal of the low-voltage battery.

摘要： [Problem] To provide a configuration for cutting off energization of an electricity storage block without interposing a controller.[Solution] The electricity storage system has: an electricity storage block including an electricity storage element (11) for performing charging and discharging; a relay (SMR-B, SMR-G) switched between an ON state in which the electric storage block is connected to a load (22, 23) and an OFF state in which a connection between the electricity storage block and the load is cut off; a controller (34) for controlling the ON state and the OFF state of the relay; and a current cutoff circuit (60) for switching the relay from the ON state to the OFF state, so as to cut off energization of the electricity storage block. The current cutoff circuit has: an alarm circuit (CMP, 62, 63) for outputting an alarm signal indicating that the electricity storage block is in an overcharged state by comparing a voltage value of the electricity storage block and a threshold; a latch circuit (64) for retaining the alarm signal; and a transistor (68) for receiving an output signal of the latch circuit and switching the relay from the ON state to the OFF state.
