Problems solved by technology

Therefore, sufficient temperature management cannot be performed in a vehicle (for example, a hybrid vehicle, etc.) that frequently switches the charging / discharging of the power storage unit according to the driving situation.
In addition, there is a problem that when the temperature management in the power storage unit is being performed, that is, during charging, the power demand from the load (motor, etc.) cannot be fully satisfied, and the driving performance of the vehicle is restricted.

Deformed example 1

[0132] According to the above-described power supply system 1 according to the embodiment of the present invention, control of the battery current Ib1 of the converter CONV1 to be temperature-managed and control of the electric power supplied to the driving force generating unit 3 can be compatible. Here, the electric power supplied to the driving force generating unit 3 corresponds to the sum of the electric power output from the converters CONV1 and CONV2. Therefore, by controlling the electric power supplied to the driving force generating unit 3 and the electric power output from the converter CONV2, it is also possible to The electric power flowing to the converter CONV1 to be temperature-managed, that is, the battery current Ib1 is indirectly controlled.

[0133] Then, in Modification 1 of the embodiment of the present invention, a configuration in which the battery current Ib1 of the converter CONV1 to be temperature-managed is indirectly controlled by controlling the ba...

Deformed example 2

[0169] The present invention is also applicable to a power supply system having three or more power storage units in addition to the aforementioned power supply system having two power storage units.

[0170] refer to Figure 11 , will describe a schematic configuration showing a main part of vehicle 100# including power supply system 1# according to Modification 2 of the embodiment of the present invention.

[0171] Vehicle 100# is in figure 1 In the vehicle 100 shown, power supply system 1# is installed instead of power supply system 1 , since driving force generating unit 3 and HV_ECU 4 are the same, and therefore detailed description thereof will not be repeated.

[0172] Power supply system 1# includes: the first group of power supply unit 200A, which will figure 1 The converter CONV1 in the shown power supply system 1 and the corresponding power storage unit BAT1 are expanded to N groups; and the second group of power supply units 200B, which is the figure 1 The conve...

Abstract

A request judging section (50) compares a battery temperature (Tb1) at a power storage section with a predetermined temperature management value (Tb1), and generates a temperature rise request or a cooling request if the difference between them is at least a predetermined threshold. A current direction determining section (54) determines in which direction a current is to be fed, to a charging side or a discharging side, for satisfying the temperature rise request or the cooling request based on the thermal reaction characteristics at the power storage section. A target current level determining section (56) determines a target current value (Ib1) associated with charging / discharging determined at the current direction determining section (54). A current control section (ICTRL1) generates a switching command (PWC1) such as the battery current (Ib1) at the power storage section matches a target current value outputted from a selecting section (60).

Description

technical field [0001] The present invention relates to a power supply system having a plurality of power storage units, a vehicle equipped with the power supply system, and a temperature management method, and in particular, to a power storage system configured to include a chemical battery while suppressing influence on power transfer to and from a load device. Department of temperature management technology. Background technique [0002] In recent years, vehicles using electric motors as a driving force source, such as electric vehicles, hybrid vehicles, and fuel cell vehicles, have attracted attention in consideration of environmental issues. Such a vehicle is equipped with a power storage unit capable of charging and discharging in order to supply electric power to an electric motor or to convert kinetic energy into electric energy for storage during regenerative braking. [0003] In such a vehicle using an electric motor as a driving force source, in order to improve ...
