Nasa BM-1 Bluetooth Battery Monitor
Nasa Marine BM-1 Bluetooth Battery Monitor
The NASA BM1(BT) Bluetooth battery monitor is supplied complete with a 100 Amp 50mV shunt and all necessary cables to connect to the main service battery. It is intended to monitor a 12 volt lead-acid battery, or bank of batteries, with a total capacity of between 5 and 600 Ampere-hours (Ahr). The current consumption of the device is typically 2 mA which represents a tiny discharge of less than 1.5 Ahr per month.
The unit monitors the main battery voltage, the current flowing into or out of the battery and calculates the best approximation of the state of charge and the time to charge or discharge. An alarm alerts the user if the charge gets dangerously low when load shedding or charging becomes necessary. A second input measures the voltage on the starter battery. As that battery is not normally under load its
open circuit voltage gives a good indication of its condition.
The information is transmitted using Low Energy Bluetooth (Bluetooth4) and can be viewed on any compatible device with a suitable App. An Android App can be freely downloaded from the Nasa Marine website while a third party more sophisticated Apple App, with additional features, can be found on the apple App store.
