Does the shared rechargeable battery consume power in the store?

In fact, the amount of power consumption of each machine is determined by the rated power of the machine, the machine’s power is high, the power consumption is high. Take the DuDu brand advertising machine as an example.

Small cabinet is 40w, one hour 0.04 degrees; large cabinet 180w, one hour 0.18 degrees.

40w cabinet an hour 0.04 degrees of electricity, but more than 60% of the time the rechargeable battery is in standby mode. According to 1 day 24 hours 0.04 * 24 * 0.4 = 0.38 (degrees / day), standby mode when only functional modules in power consumption, basically negligible (1 degree / month)

180w cabinet 0.18 degrees per hour, but more than 60% of the time the rechargeable battery is in standby mode. According to 1 day 24 hours 0.18 * 24 * 0.4 = 1.7 (degrees / day). Standby mode when only functional modules in power consumption, basically negligible (1 degree / month)

And the rechargeable battery is in standby mode 70% of the time in daily use. Only the functional module is powered there. The power consumption elsewhere is almost negligible. So the power spent by the shared rechargeable is far less than the power calculated above.
