Definitions
- the present invention relates to a power supply system having a plurality of power storage units, a vehicle including the power supply system, and a temperature management method, and particularly includes a chemical battery while suppressing the influence on power exchanged with a load device.
- the present invention relates to a technique for realizing temperature management of a power storage unit.
- Such a vehicle is equipped with a chargeable / dischargeable power storage unit to supply electric power to the motor or to convert kinetic energy into electric energy and store it during regenerative braking.
- US Pat. No. 6,60,083,396 discloses an electric motor power management system that provides a desired DC high voltage level for a high voltage vehicle traction system.
- This electric motor power management system includes a plurality of power supply stages each having a battery and a boost Z-pack DC / DC converter and connected in parallel to provide DC power to at least one inverter. And a controller for controlling the plurality of power supply stages so that the plurality of power supply stages maintain the battery voltage to at least one inverter by uniformly charging and discharging the batteries of the power supply stages.
- a power storage unit including a chemical battery stores electrical energy using an electrochemical action, so its charge / discharge characteristics are easily affected by temperature.
- temperature management is performed on chemical batteries mounted on vehicles so that the temperature is maintained within a predetermined temperature range.
- Japanese Patent Laid-Open No. 09-0 1 9 0 74 discloses a charge control system that can maintain a battery temperature during charging at an appropriate temperature.
- This charging control system includes a charger that charges a battery whose endothermic reaction is an endothermic reaction, and a control unit that controls the charging current of the charger according to the state of charge of the battery.
- the means controls the charging current so that the temperature of the battery is maintained within a predetermined temperature range by absorbing or enduring the battery based on the discharge state, the temperature of the battery, and the charging conditions.
- the present invention has been made to solve such a problem, and the object of the present invention is to appropriately control the temperature of the power storage unit while suppressing the influence on the power exchanged with the load device.
- this Ryoaki is a power supply system having a plurality of power storage units each configured to be chargeable / dischargeable.
- a power supply system according to the present invention is provided between a power line configured to be able to exchange power between a load device and a power supply system, and a plurality of power storage units and a power line, respectively, And a plurality of charge / discharge control units configured to be able to control Z discharge.
- the plurality of power storage units include at least one first power storage unit that is a temperature management target and the remaining second power storage unit, and each of the first power storage units corresponds to a power storage state.
- the power supply system includes a temperature acquisition unit that acquires the temperature of the first power storage unit, a power storage state acquisition unit that acquires the power storage state of the first power storage unit, and the temperature acquired by the temperature acquisition unit
- a request generation unit that generates a temperature increase request or a cooling request for each of the first power storage units, and a storage unit that has generated a temperature increase request or a cooling request by the request generation unit.
- At least one first power storage unit among the plurality of power storage units is set as a temperature management target. Then, when a temperature increase request or a cooling request is generated for each of the first power storage units, a current is supplied to the power storage unit in either the charge side or the discharge side based on the thermal reaction characteristics. It should be decided. On the other hand, since the second power storage unit is not subject to temperature control, the charge / discharge current can be determined relatively freely. Therefore, the second power storage unit can perform charge / discharge control according to the power requirement of the load device. Therefore, the temperature management for the first power storage unit and the response to the power request from the load device can be realized at the same time.
- the power supply system according to the present invention is based on the temperature of the first power storage unit and is a target for flowing to the charge side or the discharge side determined by the current direction determining unit.
- a target current value determination unit that determines a current value is further provided.
- control command generation unit performs charge / discharge control corresponding to the first power storage unit so that the current value of the first power storage unit matches the target current value determined by the target current value determination unit.
- a control command is given to the unit.
- control command generation unit corresponds to the second power storage unit so as to supply power corresponding to a difference between the total charge / discharge power of the first power storage unit and a power request from the load device.
- a control command is given to each of the charge / discharge control units.
- the plurality of power storage units include one first power storage unit and one second power storage unit
- the control command generation unit is a target current determined by the target current value determination unit.
