Abstract
Disclosed is a battery management system (BMS) power supply management apparatus and method. The BMS power supply management apparatus includes an optoelectronic element configured to generate a current in response to an optical signal, a conversion element configured to convert the current into a wake-up voltage, and a first switch configured to switch a wake-up signal for a BMS, in response to the wake-up voltage.
Claims18
A battery management system (BMS) power supply management apparatus, comprising:
- an optoelectronic element configured to generate a current in response to an optical signal;
- a conversion element configured to convert the current into a wake-up voltage;
- a first switch configured to switch a wake-up signal for a BMS, in response to the wake-up voltage;
- a second resistor connected to the conversion element and a battery such that the wake-up voltage is applied thereto,
- wherein the first switch is configured to switch the wake-up signal based on the wake-up voltage, and
- wherein the wake-up voltage is a drive voltage to drive the first switch, and the wake-up signal wakes up a controller to turn on the BMS.
