Energy - MAX1704x¶
Sparkfun Fuel Gauge Sensor
Status: ENERGY, COLLECTION B
Used libraries: https://github.com/sparkfun/SparkFun_MAX1704x_Fuel_Gauge_Arduino_Library
The MAX1704x are ultra-compact, low-cost, host-side fuel-gauge systems for lithium-ion (Li+) batteries in handheld and portable equipment.
MAX17043: single lithium cell
MAX17044: dual-cell 2S pack.
MAX17048: single lithium cell
MAX17049: dual-cell 2S pack.
The MAX17048 & MAX17049 are more sophisticated versions, which support a number of extra features like measuring the change rate in percent per hour to measure load or charge rate.
Device: Select the version of the MAX1704x:
MAX17044- 2-cell version of the MAX17043 (full-scale range of 10V)
MAX17049- 2-cell version of the MAX17048
Alert threshold : Set the MAX1704x’s percentage threshold that will trigger an alert.
Send Event on Alert : Send an event, to be used in rules, when the alert is set. This can be cleared with
Voltage: The measured voltage of the cell(s).
State of Charge (SoC): The percentage left of the cell.
Alert: Whether or not an alert was triggered (e.g. SoC below set threshold)
Rate: The change rate of the SoC in percent per hour. Negative value is a discharge, positive is charge rate. (MAX17048 & MAX17049 only)
Alert is triggered for a task running
Clear the alert state. An alert event will only be sent when the alert state is set. Clearing it allows for new events to be set.
