Isolated with Fault Detection

The isolation fault detection circuit can identify break downs in wire insulation.

In designs using high voltage or high power lithium ion batteries, it is often necessary for battery packs to be isolated from the chassis for safety reasons.  In these situations, active monitoring is necessary to ensure that no breakdowns of insulation have occurred.

The Orion BMS provides 2.5kV isolation between the chassis and voltage taps, as well as between groups of 36 cells for safety disconnects and fuses. 2kV Isolation is provided between the total pack voltage sensor and the control electronics / chassis.

The Orion BMS features real, active isolation fault detection that can alert the user to very small breakdowns in insulation before they become a larger problem. Unlike with other systems on the market, this feature is standard on the Orion BMS and is integrated into the central unit.
