- An assembled battery mounted on a device, a vehicle, or the like is configured by combining a plurality of storage batteries in series or in parallel in order to obtain a voltage or capacity required for the device.
- a load such as a semiconductor or a motor is connected to the secondary side of the assembled battery via a voltage converter or the like.
- the storage battery is connected in series to increase the voltage of the assembled battery.
- the capacity is increased by increasing the number of parallel devices. In this way, the combination of series / parallel is determined depending on the specifications of the device that is the load.
- Patent Document 1 describes that a battery having a minimum capacity is extracted and used as a representative storage battery for control in the process of forming a plurality of manufactured storage batteries into an assembled battery.
- the device of the early detection of the overdischarged storage battery is made
- One problem with assembled batteries is that when an external short circuit occurs in a device connected to the assembled battery, the storage battery is heated and damaged by the current.
- a thermistor or a voltage sensing circuit that performs a current interruption function for ensuring safety is mounted in a power storage system using an assembled battery, and a current interruption function that interrupts the current circuit by a signal. was configured.
- the switch that operates in the event of an abnormality is also small, and it is sufficiently possible to have the current interruption function as described above.
- the above-described current interrupting function causes a significant increase in the size of the device.
- the present invention has been made in consideration of such problems, and an object thereof is to provide an assembled battery for minimizing damage to a storage battery due to an external short circuit while suppressing an increase in size of the apparatus.
- the first storage battery and the second storage battery are connected in series, and the starting point of the diffusion-controlled region of the first storage battery is the start of the diffusion-controlled region of the second storage battery. Make it smaller than the point.
- a mechanism for minimizing damage due to an external short circuit can be constructed.
- Embodiment 1 FIG.
- FIG. 1 is a layout diagram in an assembled battery according to Embodiment 1 of the present invention.
- an assembled battery according to Embodiment 1 of the present invention includes a positive terminal 3 of the assembled battery, a conductive metal plate 4 in which copper is nickel-plated, a negative terminal 5 of the assembled battery, and one first A storage battery 6 and a plurality of second storage batteries 7 are provided.
- the storage batteries are connected in series by the conductive metal plate 4 and are stored in a line in the assembled battery case 8. Further, by arranging the positive terminals and the negative terminals of each storage battery so as to be alternately in the upper and lower directions in the figure, the current path by the conductive metal plate 4 that connects the adjacent storage batteries to the left and right in the figure is shortened.
- the storage battery with the smallest capacity reaches the lower limit end voltage at the time of discharge first, so that the capacity of the storage battery becomes equivalent to the capacity of the assembled battery.
- the assembled battery is composed of a storage battery having as much capacity and DC internal resistance as possible at the rated current.
- the first storage battery 6 according to the first embodiment of the present invention has no capacity difference with the second storage battery 7 constituting the assembled battery at the rated current, and is DC only when discharging with a large current as in a short circuit.
- the internal resistance becomes high resistance so that the capacitance becomes small. Further, the direct current internal resistance and capacity of the second storage battery 7 are not changed greatly by a change in current.
- the plus terminal 3 and the minus terminal 5 are short-circuited with a low resistance in the assembled battery having the configuration shown in FIG. 1, only the first storage battery 6 is greatly polarized, and the voltage changes from plus to minus. To the extreme. As a result, the current is stopped, and the voltage between the positive terminal 3 and the negative terminal 5 is almost zero due to the external short circuit. Therefore, the second storage battery 7 exhibits a positive voltage and flows only a current equal to or lower than the rated value. The state is stable, and damage to the second storage battery 7 is minimized.
- the first storage battery 6 was disposed at the end closest to the negative terminal 5 in the assembled battery case 8. In many cases, the recharged storage battery becomes unusable. Therefore, the first storage battery 6 to be reversed is disposed at the extreme end of the assembled battery case 8 so that the battery can be replaced even when the assembled battery is incorporated in the power storage system. It becomes easy. Even when the first storage battery 6 rarely generates heat, if the first storage battery 6 is disposed at the end, the influence on the second storage battery 7 is suppressed to the minimum.
- the DC internal resistance of a storage battery does not change greatly even if the value of the current flowing through the storage battery changes, but it is possible to manufacture a battery that increases when an extremely large current flows through the storage battery (high rate discharge).
- the extraction of the storage battery in which the DC internal resistance becomes high during high rate discharge includes a method of selecting from a plurality of manufactured storage batteries and a method of manufacturing a storage battery with high resistance during high rate discharge. Here, the latter will be described.
- the total number of batteries in the assembled battery including one first storage battery 6 and (n ⁇ 1) second storage batteries 7 is n, and the rated currents of the first storage battery 6 and the second storage battery 7 are I
- the resistance Rx when the first storage battery 6 is short-circuited is as follows: It is expressed by a formula.
- the direct current internal resistance R at normal time is generally very small. Therefore, if the direct current internal resistance at the high rate discharge of the rechargeable storage battery is n ⁇ V / I or more, the first reversal is performed as described above. It is suitable as the storage battery 6 of. Therefore, for example, when a 6 series assembled battery has a unit storage battery voltage of 4 V and a rated current of 30 A, the DC internal resistance at the time of an external short circuit is 0.8 ⁇ or more, which is suitable as the first storage battery 6.
- a lithium ion battery for the storage battery of the assembled battery which concerns on Embodiment 1 of this invention, This is a nickel hydride, an alkaline storage battery, a nickel cadmium battery, a lead storage battery, an electric double layer capacitor, a lithium ion It may be replaced with a capacitor.
- the positive electrode of a lithium ion battery is coated with a slurry of lithium cobaltate, acetylene black and PVDF binder dissolved and dispersed in an aluminum plate (or aluminum foil), which is a positive electrode current collector, and then dried and press-molded.
- the negative electrode is prepared by applying, drying, and press molding a slurry obtained by dissolving and dispersing graphite and SBR binder in a solvent on a copper plate (or copper foil) that is a negative electrode current collector.
- a solvent in which a polyolefin microporous film is sandwiched between these two electrodes, and EC (ethylene carbonate) and DEC (diethyl carbonate) in which the salt of LiPF 6 is controlled to a water content of 10 ppm or less are mixed in a volume ratio of 4 to 6.
- a battery element is produced by injecting the electrolyte solution dissolved in the battery. After this battery element is inserted into a stainless steel or aluminum container, it is precharged for gas generation at a current density of 3 A / cm 2 with respect to the electrode geometric area for 30 minutes, and then the container and the lid are sealed by laser welding in an inert gas. Is welded and sealed to produce a lithium ion battery.
- the lithium ion having a capacity of 20 Ah manufactured as described above was charged at a current of 1 C rate for 3 hours in an environment controlled at around 25 ° C., measured for a capacity value by 30 A discharge after 10 minutes of rest, and this measured value was defined as the rated current discharge capacity.
- the high-rate discharge capacity was measured under the same charging conditions, with the discharge current changed to 150A and 300A.
- FIG. 2 is a graph showing an example of capacity characteristics of a lithium ion battery measured under the above conditions.
- Curve 1 is a capacity characteristic of a lithium ion battery in which the capacity greatly decreases during a high rate discharge with a large current value, and this lithium ion battery is used as the first storage battery 6.
- the other curve 2 is a capacity characteristic of a lithium ion battery in which a capacity can be obtained even at a high rate discharge, and these lithium ion batteries are used as the second storage battery 7.
- the starting point of the diffusion-controlled region of the first storage battery 6 is smaller than the starting point of the diffusion-controlled region of the second storage battery 7, and the capacity of the first storage battery 6 indicated by the curve 1 If it becomes high, it will fall quickly from the capacity
- the first storage battery 6 is reversed due to a large current flowing when an external short circuit occurs, but the second storage battery 7 changes near an open circuit voltage.
- the capacity of the plurality of series assembled batteries is the capacity of the battery having the lowest capacity among them. Therefore, it is desirable to reduce only the capacity characteristics during high rate discharge without reducing the capacity characteristics at the rated current as much as possible.
- the internal resistance should be increased. Furthermore, as will be described below, the internal resistance during high rate discharge mainly reflects the mass transfer resistance inside the battery, and therefore the mass transfer resistance inside the battery may be increased.
- an electrode reaction and subsequent mass transfer proceed during charging or discharging.
- the main mass transfer is the movement of lithium ions in the negative electrode or positive electrode active material crystal and the movement of positive and negative ions in the electrolyte. Since the driving force for mass transfer is mainly the difference in concentration, the diffusion rate cannot catch up when charging or discharging with a large current, and the mass transfer resistance, which is an apparent resistance, becomes high. This is remarkable at the end of discharge. The region of the current value where such a phenomenon occurs is called a diffusion-limited region. Therefore, the high rate discharge capacity can be reduced by increasing the mass transfer resistance inside the battery.
- the first is a method of reducing the amount of electrolyte.
- the amount of the electrolytic solution of the first storage battery 6 is set to be smaller than the average of the amount of the electrolytic solution of the second storage battery 7.
- FIG. 3 is a table showing the capacity of the lithium ion battery with respect to the amount of electrolyte.
- the rated current discharge capacity is the capacity value when the discharge current is 30 A
- the high rate discharge capacity is the capacity value when the discharge current is 300 A.
- FIG. 3 also shows the resistance at the end of discharge. If the amount of the electrolytic solution of the first storage battery 6 is reduced to 90% or less, for example, the high rate discharge capacity can be sufficiently reduced as shown in FIG.
- the second method of increasing the mass transfer resistance inside the battery is a method of reducing the electrolyte concentration. That is, the electrolyte salt concentration of the first storage battery 6 is made lower than the electrolyte salt concentration of the second storage battery 7.
- the electrolyte of a lithium ion battery usually contains about 1 mol / L of a salt LiPF 6 as a charge carrier in an organic solvent.
- FIG. 4 is a table showing the capacity with respect to the salt concentration of the lithium ion battery.
- the rated current discharge capacity is a capacity value when the discharge current is 30 A
- the high rate discharge capacity is the capacity value when the discharge current is 300 A.
- FIG. 4 also shows the resistance at the end of discharge.
- the third way to increase the mass transfer resistance inside the battery is to increase the mass transfer rate by growing SEI (solid electrolyte interface layer) at the electrolyte interface in contact with the graphite negative electrode active material in addition to controlling the electrolyte characteristics. It can also be made.
- SEI solid electrolyte interface layer
- the manufactured battery is charged at a constant current to a charge level of 100%.
- a thick SEI layer is formed on the graphite surface layer intercalated with lithium. This increases the mass transfer resistance when lithium ions move from the active material phase to the electrolyte solution by diffusing in the SEI layer during discharge.
- the high rate discharge capacity of the first storage battery 6 can be reduced.
- the assembled battery according to Embodiment 1 of the present invention includes the specific battery 6 having a relatively low capacity-current characteristic, and the first storage battery 6 is reversed due to a large current flowing when an external short circuit occurs. The damage of the 2nd storage battery 7 can be avoided.
- the assembled battery cuts off the current independently, an external short circuit occurs when the poles at both ends of the assembled battery are short-circuited during the assembly process, when the system is assembled after assembly, when an external load is connected, or before the system is started. Even when the sensors do not function, for example, the storage battery can be prevented from being damaged or the connected device from being damaged due to self-heating due to the large current discharge.
- the power storage system to which this assembled battery is applied can be reduced in size and weight.
- first storage batteries 6 There may be a plurality of first storage batteries 6.
- the plurality of first storage batteries 6 are sacrificed when an external short circuit occurs, but the other second storage batteries 7 can be protected.
- FIG. FIG. 5 is a partial configuration diagram of a power storage system shown as a comparative example of the assembled battery according to Embodiment 2 of the present invention.
- 10 is a battery
- 15 is a voltmeter that measures the voltage of each battery
- 9 is a polarity detection unit that detects the polarity of each battery from a change in voltage based on a voltage signal from the voltmeter
- 17 Is a failure signal transmission / storage unit that transmits a failure signal and stores a failure history when a polarization signal sent from the polarization detection unit 9 is received.
- the assembled battery is incorporated in the power storage system and the assembled battery is supplied with power from an external auxiliary power source and is in an operating state, when the external battery is short-circuited, as shown in FIG. Can be measured.
- the voltmeter 15 sends a voltage signal corresponding to the measurement result to the inversion detector 9. Then, the reversal detection unit 9 can determine which storage battery has a reversal from the voltage signal.
- the failure signal transmission storage unit 17 can receive a signal for informing the polarity change from the inversion detection unit 9, thereby transmitting a failure signal for notifying the external device of the failure and storing the history of the inversion.
- power for monitoring the assembled battery such as transmission of a failure signal and storage of the history of reversal needs to be covered by the power of the assembled battery itself.

- the battery that reverses polarity in this assembled battery is the storage battery 6 that is arranged at a specific position and has high resistance during high rate discharge. Therefore, if this single cell voltage is representatively monitored, the presence or absence of inversion, that is, the presence or absence of an external short circuit can be detected. Further, since the second storage battery 7 other than the specific battery 6 does not invert when it is short-circuited, it can be used as a drive power source for detecting inversion and transmitting / storing a failure signal. Therefore, in this assembled battery, even if the system is not operating, it is possible to detect and store a short circuit.
- the voltmeter 16 that measures the voltage of the first storage battery 6 sends a voltage signal to the inversion detector 19 to notify the inversion.
- the inversion detection unit 19 detects the inversion and sends the inversion signal to the failure signal transmission / storage unit 17.
- the failure signal transmission / storage unit 17 transmits a failure signal for notifying the external device of the failure, and stores the reversal history.
