The Altertek Battery Management System (BMS) is the flagship product with multi voltage capability, 1A per cell passive cell balancing and CAN Bus communication.
This has been designed from the ground up by our engineers and has proved to be a great foundation product for custom solutions all manufactured and supported in the UK.
This Battery Management System can work as a standalone battery pack, or can be connected together to form higher voltage (or capacity) systems, which can communicate with one another for optimum system performance.
It is designed as a general purpose BMS and has an optional solid state switching module for the full battery power management. This allows selective control of the charge, discharge and pack current. When connected in parallel with other packs, it also provides reverse current protection and can disconnect a pack when a fault is detected.
The system has a 3 LED onboard voltage based State of Charge to give an approximate SOC reading and fault LED which can be simply connected to an external location from one of the headers for external monitoring.
The system has been designed to be scaled up to XXXV in series and has ZZZohm insulation for protection and will communicate automatically over CAN Bus for complete pack balancing and fault indication.
The system has two 500mA relay drivers which can be used to drive cooling fans or a heating element or any exterior device that can be activated by a relay.
The system has been designed to be draw as little power as possible and as a result has a quiescent current of only YYYYYA making it ideal for long term storage.
The system has been designed with primary software controlled under and over voltage protection with secondary hardware back giving complete redundancy.
