BCU-NEV EV Power Lithium Battery Control Unit

$385.00

BMS-BCU-NEV+04C – 12V
BMS-BCU-NEV+08C – 24V (2 x EV PowerPak in series)
BMS-BCU-NEV+12C – 36V (3 x EV PowerPak in series)
BMS-BCU-NEV+16C – 48V (4 x EV PowerPak in series)

A powerful device in a small package this battery control unit is designed to work with 12V EV PowerPaks to deliver trouble free power for portable power applications. The BCU-NEV provides two additional functions over the BCU-PPAK.
1) Pre-charge capability for inverters and capacitive loads.
2) Remote mountable Monitor showing battery state of charge and other information.

BMS (Battery Management System).

Our EV PowerPak systems have half of the BMS on the battery (Cell Modules) and half in the BCU (Battery Control Unit). It is the BCU that will switch off the battery if you try to do something bad. The battery cells themselves are not protected except for balancing and monitoring. One BCU-PPAK or BCU-NEV can handle up to three batteries in parallel and will isolate the batteries from each other and the load when switched off.

Description

The BCU-NEV has an attached current shunt that allows it to monitor total battery current and make State of Charge estimations. Note that it is not possible to tell the state of charge of a LiFePO4 battery from the terminal voltage.

Features:

  • Remote mount Monitor display for easy to read battery information at a glance.
  • Low power consumption (<15mA) even when discharge contactor is on.
  • Monitors overall battery voltage minimum and maximum.
  • Monitors the battery management system (BMS) loop.
  • 240A (3 x 80A) contactor isolates the batteries from the load and each other if there is a problem.
  • 12V (4C), 24V (8C), 36V (12C) and 48V (16C) versions available.
  • Can control up to three EV PowerPak strings in parallel.
  • Australian Designed and Manufactured.

Note: Our BCUs employ an internal latching relay/contactor. As such they have very low internal resistance compared to Mosfet BMS’s. They can tolerate very high transient currents. This means that they always isolate current flow in both directions when off.
