Title:
BATTERY MONITORING SYSTEM
Document Type and Number:
Japanese Patent JP2022077901
Kind Code:
A
Abstract:
To stably sense a current value and a voltage value which are synchronized to each other with a simple configuration.SOLUTION: A control device 40 senses a current value of a battery pack at timing when a predetermined current sensing standby time T1 elapses after the generation of a voltage sensing instruction signal Svd. The control device 40 repeatedly carries out the transmission of the voltage sensing instruction signal Svd in a case that reception of the voltage sensing instruction signal Svd by a monitoring device 30 cannot be confirmed. Meanwhile, the monitoring device 30 acquirers a voltage sensing standby time T2 acquired by subtracting a retry time T3 taken by repeating the transmission of the voltage sensing instruction signal Svd from the current sensing standby time T1. After the reception of the voltage sensing instruction signal Svd, the monitoring device 30 senses a voltage value of each battery cell at timing when the voltage sensing standby time T2 elapses.SELECTED DRAWING: Figure 4
