Definitions
- the present invention relates to a vehicle power supply device to be mounted on a vehicle.
- lead-acid batteries Electric power is supplied from the lead storage battery to the starter motor and various electrical components.
- lead acid batteries are inexpensive, they have a characteristic that their cycle life is short compared to nickel metal hydride batteries and lithium ion batteries. In vehicles having an idling stop function, the number of times of charging / discharging increases, so the life of the lead-acid battery is particularly short.
- the above-described switch may be turned off at a normal time due to a defect in wiring for transmitting the control signal. There may be a case where the malfunction of the switch cannot be recognized from the controller outputting the control signal.
- the present invention has been made in view of such circumstances, and an object of the present invention is to provide a technique for accurately detecting a malfunction of a switch inserted between power storage units connected in parallel to be mounted on a vehicle.
- the in-vehicle power supply device is mounted on a vehicle having an idling stop function and a deceleration energy regeneration function.
- the idling stop function is a function that automatically stops the engine when the vehicle stops and restarts the engine automatically when starting.
- the deceleration energy regeneration function is a function that generates power intensively at the time of deceleration when the engine is rotating due to inertia regardless of fuel. That is, during normal driving, the operation of the alternator is suppressed as much as possible to reduce the engine load. Both functions have the effect of improving fuel consumption.
- the number of engine starts increases in vehicles equipped with an idling stop function.
- the engine is usually started by a starter motor driven by battery voltage. Therefore, as the number of engine starts increases, the power consumption of the battery increases and the number of discharges increases.
- a vehicle equipped with a deceleration energy regeneration function is intensively activated during deceleration, a battery capable of efficient charging with a large capacity is required.
- FIG. 1 is a diagram for explaining an in-vehicle power supply device 100 according to an embodiment of the present invention.
- an alternator 200 In a vehicle on which the in-vehicle power supply device 100 is mounted, an alternator 200, a starter 300, an electrical component 400, and an ECU (Electronic Control Unit) 500 are mounted as members related to the in-vehicle power supply device 100.
- an alternator 200 In a vehicle on which the in-vehicle power supply device 100 is mounted, an alternator 200, a starter 300, an electrical component 400, and an ECU (Electronic Control Unit) 500 are mounted as members related to the in-vehicle power supply device 100.
- an alternator 200 In a vehicle on which the in-vehicle power supply device 100 is mounted, an alternator 200, a starter 300, an electrical component 400, and an ECU (Electronic Control Unit) 500 are mounted as members related to the in-vehicle power supply device 100.
- an alternator 200 In a vehicle on which
- the alternator 200 generates power by the rotational energy of the crankshaft of the engine (not shown). In the present embodiment, power is generated mainly during deceleration. The alternator 200 supplies the generated power to the in-vehicle power supply device 100.
- the starter 300 is an engine starting motor.
- the starter 300 is rotated by the electric power supplied from the in-vehicle power supply device 100 and starts the engine.
- an ignition switch (not shown) is turned on by the driver's operation, power is supplied from the in-vehicle power supply device 100 to the starter 300, and the starter 300 is started.

- a vehicle such as a headlight, a power steering, an oil pump, a car navigation system, and an audio.
- the alternator 200, the starter 300, and the ECU 500 are drawn separately from the electrical component 400.
- the electrical component 400 is driven by electric power supplied from the in-vehicle power supply device 100.
- ECU 500 is connected to various auxiliary devices, sensors, and switches mounted in the vehicle, and electronically controls the engine and various auxiliary devices.
- ECU 500 stops the engine when it detects stop of the vehicle or deceleration to a set speed or less based on a signal input from a brake, a vehicle speed sensor or the like. Further, ECU 500 restarts the engine when it detects that the brake is released. At that time, control is performed so that electric power is supplied from the in-vehicle power supply device 100 to the starter 300, and the starter 300 is operated.
- the ECU 500 When executing the deceleration energy regeneration function, the ECU 500 basically stops the alternator 200 during normal driving. ECU 500 activates alternator 200 when it detects deceleration of the vehicle based on signals input from a brake, a vehicle speed sensor or the like. When the capacity of the battery in in-vehicle power supply device 100 is lower than the set lower limit capacity, ECU 500 operates alternator 200 even during normal travel.
- a lead storage battery is used for the first storage battery 10 and a nickel hydride storage battery is used for the second storage battery 20.

- Some electrical components 400 are reset when the voltage drops to about 10 V, such as a car navigation system.
- the starter 300 is operated, the potential of the charge / discharge terminal of the second storage battery 20 is stabilized by turning off the first switch S1, and a stable voltage can be continuously supplied to the electrical component 400.
- the diode D1 is provided in parallel with the first switch S1.
- the diode D1 is connected such that the cathode side is the second storage battery 20 side and the anode side is the first storage battery 10 side.
- Current flows from the alternator 200, the starter 300, and the first storage battery 10 side to the second storage battery 20 and the electrical component 400 side via the diode D1 in the state where the first switch S1 is off. It will not flow.
- the second storage battery control unit 40 manages and controls the second storage battery 20.
- the 2nd storage battery control part 40 is demonstrated more concretely.
- FIG. 2 is a diagram for explaining the second storage battery control unit 40 of FIG. 1.
- the second storage battery control unit 40 includes a key input detection circuit 41, a high side switch 42, a constant voltage generation circuit 43, a battery state detection circuit 44, a communication interface 45, a CPU 46, a memory 47, and a switch control circuit 48.
- the constant voltage generation circuit 43 generates a power supply voltage for the CPU 46 and the switch control circuit 48.
- the 12V voltage of the path P1 is stepped down to a voltage of about 3 to 5V.
- a three-terminal regulator can be used for the constant voltage generation circuit 43.
- the battery state detection circuit 44 acquires the voltage, current, and temperature of the second storage battery 20.
- the second storage battery 20 is provided with a shunt resistor (not shown), and the current flowing through the second storage battery 20 can be detected by monitoring the voltage across the shunt resistor.
- the second storage battery 20 is provided with a thermistor (not shown), and the temperature of the second storage battery 20 can be detected.
- the battery state detection circuit 44 notifies the CPU 46 of the voltage, current, and temperature of the second storage battery 20.
- the communication interface 45 is an interface for communicating with the second storage battery control unit 40 and other control circuits (first storage battery control unit 30 and ECU 500 in the present embodiment).
- the communication interface 45 transmits information received from the outside to the CPU 46 and transmits information output from the CPU 46 to the outside.
- the communication interface 45 transmits the abnormality detection of the second storage battery 20 or the second storage battery control unit 40 to the ECU 500.
- the state information for example, voltage, current, temperature
- the state information of the second storage battery 20 is transmitted to the ECU 500.
- on / off information of the first switch S1 is transmitted to the ECU 500.
- a power generation request by the alternator 200 is transmitted to the ECU 500.
- the switch control circuit 48 switches the first switch S1 on / off in accordance with an instruction from the CPU 46.
- the first switch S1 is a relay
- the energization / non-energization of the relay coil is controlled.
- the first switch S1 is a semiconductor switching element
- the gate voltage is controlled.
- the first switch S1 is a relay, an open failure may occur. Even when the first switch S1 is a semiconductor switching element, current may not flow even when a specified gate voltage is applied due to malfunction. Further, the control of the first switch S1 by the CPU 46 may be disabled due to a failure of the switch control circuit 48, a disconnection between the switch control circuit 48 and the first switch S1, or the like.
- the power supply to the electrical component 400 is maintained because the second storage battery 20 is connected to the path P1. Even if the first switch S1 breaks down, the electrical component 400 or the second storage battery 20 does not immediately have a malfunction, and therefore the failure detection of the first switch S1 may be delayed. If the failure is left unattended, the second storage battery 20 is likely to be overdischarged. Moreover, the efficiency of the electric power supplied from the alternator 200 or the first storage battery 10 to the electrical component 400 is lowered by the forward voltage drop Vf of the diode D1.
- FIG. 3 is a flowchart for explaining a failure determination process of the first switch S1 by the second storage battery control unit 40 according to the embodiment. This failure determination process is based on the premise that a signal for controlling the first switch S1 to be turned on is being supplied from the second storage battery control unit 40 to the first switch S1.
- the second storage battery control unit 40 acquires the voltage V1 of the first storage battery 10 from the first storage battery control unit 30 (S10). Moreover, the voltage V2 of the 2nd storage battery 20 is acquired. The second storage battery control unit 40 compares the differential voltage (V1-V2) with the forward drop voltage Vf of the diode D1 (S14). Since the on-resistance of the first switch S1 is negligible, when the first switch S1 is in the on state, the differential voltage (V1-V2) is substantially zero. On the other hand, when the first switch S1 is in the OFF state, the differential voltage (V1-V2) substantially matches the forward drop voltage Vf.
- step S14 when the differential voltage (V1-V2) and the forward voltage drop Vf substantially match (Y in S14), the second storage battery control unit 40 determines that the first switch S1 is normal (S16). When the differential voltage (V1-V2) and the forward voltage drop Vf do not substantially match (N in S14), the second storage battery control unit 40 determines that the first switch S1 or its control system is abnormal (S18), The abnormality is notified to ECU 500 (S20). Upon receiving the notification, ECU 500 performs stop control of alternator 200, alert notification to the driver, and the like.
- the failure determination process described above is basically executed when the second storage battery control unit 40 is activated. In addition, even after starting of the 2nd storage battery control part 40, you may perform regularly.
- the voltage of the first storage battery 10 was used as the terminal voltage on the anode side of the diode D1.
- the set output voltage value of the alternator 200 may be used, and when the DC-DC converter is provided at the subsequent stage of the alternator 200, the set output voltage value of the DC-DC converter may be used as it is.
- the failure of the first switch S1 inserted between the first storage battery 10 and the second storage battery 20 connected in parallel is detected by the diode D1 connected in parallel to the first switch S1.
- This can be accurately detected by using the forward voltage drop Vf. That is, the first switch S1 is turned on by comparing the difference between the voltage of the first storage battery 10 on the anode side of the diode D1 and the voltage of the second storage battery 20 on the cathode side and the forward drop voltage Vf of the diode D1. It is possible to accurately detect whether it is in the off state.
- the voltage detection circuit of the 1st storage battery 10 and the 2nd storage battery 20 can be diverted, it is not necessary to newly provide another voltage detection line. Therefore, the failure determination of the first switch S1 can be performed without increasing the cost.
- the second switch S2 is provided to prevent overcharge and overdischarge of the second storage battery 20. Moreover, it has the effect
- a nickel metal hydride storage battery or a lithium ion storage battery has a lower internal resistance than a lead storage battery and a current easily flows, and thus is easily overcharged or overdischarged.
- FIG. 5 is a flowchart for explaining a failure determination process of the first switch S1 by the second storage battery control unit 40 according to the modification.
- the flowchart of FIG. 5 is obtained by adding the process of step S19 to the flowchart of FIG. In this failure determination process, it is assumed that a signal for controlling the first switch S1 to be turned on is supplied from the second storage battery control unit 40 to the first switch S1, and that the second switch S2 is in the on state. .
- the second storage battery control unit 40 determines that there is an abnormality in the first switch S1 or its control system (S18), in the modified example, the second switch S2 is controlled to be turned off (S19), and the abnormality is notified to the ECU 500 ( S20). Upon receiving the notification, ECU 500 performs stop control of alternator 200, alert notification to the driver, and the like. According to the modification, by turning off the second switch S2, it is possible to suppress the second storage battery 20 from being overdischarged before the first switch S1 is replaced or repaired.
- a fuse may be inserted between the path P1 and the second storage battery 20 described above.
- the second storage battery 20 can be protected from a large current.
