Title:
MANAGEMENT DEVICE AND ACCUMULATOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/042764
Kind Code:
A1
Abstract:
In order to realize a temperature control system for an accumulator unit at a low cost while ensuring safety, a first temperature detection unit (11) detects the temperature of a high-temperature area and the temperature of a low-temperature area in an accumulator unit (20) on the basis of output values from a first temperature detection element (T1) which is installed in a first location in the high-temperature area of an accumulator unit (20), and a temperature detection element (T3) which is installed in a prescribed location in the low-temperature area of the accumulator unit (20). A main control unit (13) controls charging and discharging of the accumulator unit (20) on the basis of the temperature of the high-temperature area and the temperature of the low-temperature area detected by the first temperature detection unit (11). A second temperature detection unit (12) detects the temperature of the high-temperature area in the accumulator unit (20) on the basis of the output value from a second temperature detection element (T2) which is installed in a second location in the high-temperature area of the accumulator unit (20). When a malfunction occurs in the main control unit (13), a secondary control unit (14) controls charging and discharging of the accumulator unit (20) on the basis of the temperature of the high-temperature area detected by the second temperature detection unit (12).
