Battery system
View Patent ↗This battery system includes: a plurality of batteries; a first monitoring unit that receives as input the output of the batteries, compares the output with a prescribed threshold value, and supplies a signal indicating the result; and a second monitoring unit that detects the voltage value of the batteries and supplies a signal indicating the detected voltage value. The battery system is provided with: a first operation mode during which the first monitoring unit and the second monitoring unit are halted; a second operation mode during which the first monitoring unit operates and the second monitoring unit is halted; and a third operation mode during which the first monitoring unit and the second monitoring unit operate.
1. A battery system comprising:
a plurality of batteries;
a first monitor unit that receives as input the outputs of said batteries, compares said outputs with a predetermined threshold value, and supplies a signal indicating the result; and
a second monitor unit that detects the voltage values of said batteries and supplies a signal indicating the detected voltage values;
wherein said battery system is provided with:
a first operating mode in which said first monitor unit and said second monitor unit are halted, a second operating mode in which said first monitor unit operates and in which said second monitor unit is halted, and a third operating mode in which said first monitor unit and said second monitor unit operate.
2. The battery system as set forth in claim 1 , further comprising:
a charge/discharge switch that is provided on wiring that connects said batteries and an object that is to be connected to said battery system and that turns ON or OFF according to at least one of a signal supplied from said first monitor unit and a signal supplied from said second monitor unit.
3. The battery system as set forth in claim 1 , wherein the second monitor unit has a greater average power consumption than the first monitor unit.
