With accurate information, military personnel can make informed decisions. When combined, their accuracy is so great that DataCell II provides SoC within 2% and SoH within 1%. Neither amp hour counters nor model based monitors can calculate SoH in isolation. The Battery Monitoring ChallengeĭataCell II combines the accuracy of amp hour counting and a proprietary battery model that never needs synchronization. military casualties in Afghanistan are due to improvised explosive devices many of these devices are placed in the path of supply convoys carrying fuel1. Pentagon officials have told the House Appropriations Defense Subcommittee a gallon of fuel costs about $400 by the time it arrives in remote regions of Afghanistan. Due to lack of confidence in power availability, crews continuously idle their engines to ensure battery banks are charged. Vehicles typically carry 2 to 8 batteries which can cost $4,000 each when logistical costs are accounted for.
Inadequate power management such as excessive discharge, improper charging, and inadvertent abuse leads to premature battery failure. Massive costs are incurred to supply the US military with batteries and fuel. The consequences of inadequate electrical systems for today’s warfighter manifest themselves in many ways including economic costs, decreased capability, and ultimately lives put at risk. The original design of electrical systems did not account for the power storage, generation, monitoring, and management required to operate electronic counter measures, communications, computers and displays, sensors, remote weapon systems, and other electronics. The US military’s ground and maritime mobility platforms in Iraq and Afghanistan have experienced significant problems generating and distributing enough power for on-board systems. SoH is the measure of the capacity decrease and the battery is said to be at 90% SoH. The capacity of the 100Ah battery in our example may decrease to 90Ah after regular use. For this battery Merlin defines 50Ah remaining as 0% SoC 100Ah remaining is 100% SoC so for example 75Ah remaining would be 50% SoC. Ideally, a 100 Ah battery should not be discharged below 50Ah. SoC is often thought of as the equivalent of a fuel gauge for a battery bank in this analogy, SoH would be the size of the gas tank.ĭischarging a lead-acid battery to less than half of its capacity is not recommended because it begins to cause internal damage to the battery. The purpose of battery monitoring is to obtain accurate State of Charge (SoC is a percentage of battery capacity remaining) and State of Health (SoH is the capacity of the battery as a percent of its original capacity) readings.
