1PS BMS is a complete solution for management of high-voltage and low-voltage battery energy storage installations. It provides precise cell monitoring and balancing as well as overall battery protection against overcurrent, short circuit failures, overdischarge and other common problems. All presented in a modern UI and expandable to your needs.
The 1PS BMS is designed for both high and low voltage battery storage installations and supports a wide range of battery cells and combinations. Designed for voltages from 24 to 1000V DC and discharge currents up to 775 Amps.
1PS BMS consists of three basic components:
PCM-2
Power compute module
This is the real brain of the system. Powerful ARM based computer with modern and sleek UI and dual IsoSPI bus for up to two independent battery connection.
BGP-9
Battery gas gauge and protection module
Safely connects your battery and protects it against most common problems, such as overcharge, overdischarge, short circuit failures. It also measures every wattsecond of charged and discharged energy to or from the battery.
CMS-12
Cell management and balancing module
This module provides precise realtime cell voltage monitoring and balancing of up to 12 cells. Can be daisy-chained up to 240 cells (20 modules with 12 cells each).
Features
- Smart passive battery balancing
- Cell overvoltage and undervoltage protection
- Battery overvoltage, undervoltage, overcurrent protection
- Temperature monitoring
- Communication with inverter with SunSpec protocol via RS485
- Lead-acid and Lithium-based chemistry compatible
Typical usage
Turn EV batteries into home or commercial energy storage devices
Our clients have successfully converted their BMW i3 and Chevrolet Volt battery modules into home energy storage units using 1PS BMS.
For BMW i3 battery packs we offer a complete conversion of the battery to an energy storage device.
