The LV-BMS is a part of our Intelligent range of products meaning it incorporates many advanced features as standard that are required for modern complex energy storage systems such as CAN Bus communications, state of charge calculation, state of health calculation, charger control, configurable GPIOs and contactor drivers with pre-charge control.
All of Altertek’s Intelligent Battery Management Systems can be configured using our proprietary AlterVU software which is free to all users who have purchased an Altertek Battery Management System. Find out more about AlterVU and how it can decrease the cost and speed of your next project.
AlterVU allows a user to change just about every parameter conceivable of the BMS, allowing the BMS to be completely tailored to the product without hard coding decreasing time to market and overall engineering costs.
The BMS also has a powered expansion header allowing custom modules to be purchased or developed and easily integrated. The expansion header can support additional features such as (but not limited to):
The expansion header can also be expanded upon its-self – up to three times providing further ease of integration into even the most complex of systems.
Security has been built in from the very beginning. The BMS has both hardware and software security features to prevent accidental or malicious changing of the configuration or theft of the data being generated. The BMS has multi level security including:
If updates need to be made periodically, then a set of header pins are provided that can be connected to a key switch which can be mounted externally on the product. This allows a technician to make configuration changes while the key switch is active, but then once removed, user or remote configuration changes are prevented.
