Document Type and Number:
WIPO Patent Application WO/2022/244560
Kind Code:
A1
Abstract:
Provided is a control device 130 for an automotive energy storage cell, the energy storage cell 62 having, in terms of battery performance, a first region and a second region where the battery performance is lower than that in the first region. When the energy storage cell 62 transitions from the first region A1 to the second region A2, the control device 130 outputs a signal notifying a vehicle control unit 140 that controls a vehicle 10 of the transition of the regions A, and, after outputting the signal, maintains a current cutoff device 53 that cuts off a current I of the energy storage cell 62 closed for at least a prescribed time Tw to enable power supply to the vehicle 10.
