Embodiment 1

[0054] in Figure 1~2 An example of application to a power supply device for in-vehicle use is described as the power supply device according to the first embodiment of the present invention. The power supply device 100 is mainly mounted on an electric vehicle such as a hybrid vehicle or an electric vehicle, and is used as a power source for supplying electric power to a motor of the vehicle to run the vehicle. However, the driven equipment connected to the power supply device of the present invention is not limited to this. It can also be used in electric vehicles other than hybrid vehicles or electric vehicles, and can also be used in applications requiring large output other than electric vehicles. .

[0055] figure 1 It is a block diagram showing that the power supply device 100 is installed in a hybrid vehicle that runs on both an engine and an electric motor. figure 1 The vehicle HV equipped with the power supply device 100 shown includes: an engine 96 for driving the vehi...

Abstract

The invention provides a power supply device, a vehicle and a storage battery device employing same, capable of specifying deterioration causes of a battery in a simpler structure. The power supply device comprises a plurality of chargeable secondary cell units; a temperature detection unit(31) for detecting temperature of a battery block (9) formed by secondary cell units in serial or parallel connection; a current detection unit (32) for detecting charging and discharging current of the battery block (9); and a voltage detection unit (33) for detecting the voltage of the battery block (9) or the secondary cell units. The power supply device further comprises a data collecting unit for obtaining temperature detected by the temperature detection unit(31), the current value detected by the current detection unit (32) and the voltage valve detected by the voltage detection unit (33) at regular time; and a storage unit (20) for recording data collected by the data collecting unit.

Description

Technical field [0001] The present invention relates to a power supply device capable of supplying electric power by incorporating a plurality of battery cells connected in series or in parallel, a vehicle including the power supply device, and a power storage device. Background technique [0002] A power supply device that has many built-in secondary battery cells to increase both output voltage and output current can not only be used in hybrid vehicles, electric vehicles, etc., but also used as a mounted type that accumulates electricity for household and industrial use. It is expected to be utilized in power storage applications such as the power supply device. [0003] In such a power supply device, the secondary battery cell is deteriorated due to various reasons. However, in power supply devices actually used under various environments and conditions, there are various causes, and it is not easy to specify the cause. [0004] In order to identify such a reason, a method of co...
