UNDERSTANDING THE HOT-SWAP BATTERY PLATE

Post by Sam on Fri Nov 29, 2013 11:13 am

As many of the staff know, we have the ability to provide a "Hot Swap Battery Plate" to customers at an additional cost. The standard WMT units come with a single v-mount or gold-mount battery plate. Many customers like the idea of being able to change batteries while the unit is running, without the need to shut down the unit. Please understand that this is exactly what the hot-swap plate was designed for. There is a misconception that the dual battery plate allows for both batteries to power the unit at the same time. This is not the case. Placing 2 batteries on the plate at the same time does not provide any additional power or voltage to the unit. The unit only draws what it needs and will select the battery with the greater charge initially. As the unit runs and the battery starts to drain, there will be a minimum power threshold at which the unit will no longer function due to the lack of power and the battery will shut off or stop producing enough power for the unit to function. It is at this moment that the plate will allow for a switch to the second battery and start consuming the power from the second battery.

Therefore, having 2 batteries attached at the same time, does not necessarily double the power but essentially it doubles the transmission time. When one battery, dies, the second battery will kick in and take over and keep the unit running until it also has drained below the minimum threshold for which the unit can function and unless the first battery is replaced prior to this point, the unit will shut down.

Thanks Mike....

But I saw many times after 3-4 hour some SIMS went in dialing mode. So how is it possible.

3-4 with the hot swap? My understanding is that the battery life will be 3-4 on a single battery. Maybe the connectivity issue is unrelated to the power; I'm not sure that I've noticed SIMs losing connection toward the end of the battery life.

I think there is no connection between battery life and connectivity . I just need to know why after 3-4 hour some sims went to connecting and dialing. but according to you we can give live for +/- 8 hours continuously.

The Battery Power or Device running is nothing to do with SIM Connections. The disconnection of SIM could be for different reasons like Network Congestion, Data Low or it could be some other network related issue. Our units are designed to work 24 X 7 however in real field application they are not used as such and coverage is done on small intervals.

Just ran into something interesting that made me think of this topic:

After the battery dying on the unit, it was swapped for a fresh battery. At this point, all SIM connections failed, cycling between "config" and "tmpdisabled." It was rebooted 4 times using the power button en route back to me. Upon its return, I booted it and it immediately connected across all SIM connections.

My initial thoughts would be a dead-zone or an error resulting from the sudden shutdown. But, it failed to reconnect over a distance of 10km (with 3 different carriers, with 2.5mbps BW prior to shutdown) and 4 power cycles, which seems strange. Perhaps it just needed a longer cool-down period?

What brand batteries are you using?
