Battery Management Systems

The new Hardy BMS boxes are here!

FLEX BMS is now available.

The Flex BMS-48 provides a complete Battery Management and Monitoring System solution for Lithium based electric vehicles. This version of the Flex BMS product is designed to support 25-48 cell Lithium-ion based electric vehicles which are typically DC powered, highway capable vehicles (80v-192v). The Flex BMS is not chemistry specific and can be programmed for almost any type of Lithium chemistry cell.

The BMS architecture has a centralized data collection system and a small dash mounted display Console. The data collection system monitors the voltage on each battery and provides a battery balancing function. The dash console provides a simple user interface to provide the primary battery condition information to the user. The dash Console does not have to be constantly monitored; it will provide alerts when there is a battery problem or when batteries have reached their low voltage point.

The features of the Flex BMS are:

• Dash mounted status display, provides simple viewing of battery system.
• Centralized Monitoring of individual cell voltages, up to 48 Lithium cells.
• Up to 2 external temperature probes, and internal temperature probes.
• Fully configurable Upper voltage threshold, Low Voltage Threshold, and Balance voltages
• Configurable temperature threshold for alerts.
• Automatic battery balancing, up to 1A per cell
• Integrated, isolated charger cutoff switch, up to 240V, 25A, (Supports Zivan NG-3)
• Balance at the end of each charge cycle and a separate Balance mode to balance cycle the batteries.
• Fully isolated architecture requires no vehicle 12v power or connections to controller components.
• Built-in logging function allows viewing of recent BMS activity and alerts.

Production is underway for the standard configuration.

BMS Pricing:

• 48 Cell system, including BMS Box, connectors, Basic display and display cable: $998
