Title:
LITHIUM-ION BATTERY MODULE
Document Type and Number:
WIPO Patent Application WO/2022/186363
Kind Code:
A1
Abstract:
A lithium-ion battery module is provided which outputs an optical signal corresponding to the state of multiple laminated battery cells that configure a battery assembly. This lithium-ion battery module includes multiple optical transmitters (10) provided on multiple battery cells (30) that configure a battery assembly (50). Each optical transmitter is configured to be provided with a control circuit (40) which receives from a measurement circuit (90) a characteristic signal representing a characteristic of the corresponding battery cell and which outputs a prescribed control signal; and a light-emitting unit (20) which outputs an optical signal, corresponding to the control signal, to an optical waveguide (60) common to the multiple optical transmitters. The control circuit (40) is provided with a state determination circuit (42) which determines the state of the corresponding battery cells on the basis of the received characteristic signal, and is configured to control the light-emitting unit (20) so as to output different-pattern control signals in response to the determined state, and to output different-pattern optical signals in response to the determined state.
