The BCM Battery Monitor from Philippi is a state-of-the-art, highly accurate instrument that employs digital data transfer between the Shunt and Monitor. To achieve this, the Shunt is equipped with a 16 bit micro processor that converts the current reading to digital data before then transferring it to the Monitor. The result is high overall accuracy and reliability, especially accumulatively over time, as the measurements are made at the Shunt and not at
the end of a pair of wires extended to the Monitor, which are susceptible to induction, interference or losses.
The BCM 1 is ideal for full monitoring of one main battery plus voltage indication of two auxiliary batteries. It requires one Shunt installed in the battery negative line, for a maximum continuous current of either 300 amp or 600 amp. The BCM 2 can fully monitor two main batteries and show voltage of two auxiliary banks, and requires two shunts. Both the BCM 1 and BCM 2 are available in flush mount (standard), or with an optional built-out housing. A high voltage version, the BCM 48, is available for battery systems of 36 to 48 volts, and the BCM-R version incorporates relays for remote generator start and stop at user-defined capacity levels. BCM-R relay outputs are either on-off or pulse on-pulse off.
The large, easy to read, illuminated LCD screen shows main battery volts and discharge/charge current, while a large battery graphic indicates the charge level and shows State of Charge in amp/hours. Also shown is time-to-go at the present rate of current draw. A separate, smaller battery symbol shows the voltage of a second or third battery, if connected. The exceptionally low current draw (2.5 mA at 12v) allows for continuous operation.
A visual and audible (buzzer) alarm can be set for the main battery, with a user-adjustable capacity threshold, and adjustable low voltage alarms can be set for second and third batteries, if connected.
Other features include provision for the Peukerts number to be entered according to the type of battery connected, plus indication of: Charge Efficiency Factor, Number of Cycles, and Number of Deep Discharges.
