Charge-M8 Libra
Dynamic Load Balancing for Commercial EV Charging Infrastructure
What is Libra?
Libra is Charge-M8's dynamic load balancing device, designed for commercial EV charging sites.
In conjunction with OCPP-compliant CPMS platforms, bi-directionally manages power between the building and connected EV chargers via OCPP, dynamically reallocating available capacity to maximise charging infrastructure without increasing supply limits.

Live Data to Your OCPP Platform
Integrated with Tap Electric, Nemiah, Clenergy EV, SaaScharge and other OCPP platforms to deliver intelligent energy management across commercial charging sites.
In 2025, our Libra and Tap Electric solution received nominations at both the EVIES Awards and the ECN Awards.
Real-Time OCPP CPMS Tracking
The Charge-M8 Libra is a pre-configured dynamic load balancer that continuously monitors a building's power consumption and redistributes available capacity across multiple charge points in real time.
Charge Points Stay Up to Date
Maximises existing supply and enables more chargers without expensive infrastructure expansion, reducing total project costs significantly.
Supports OCPP-compliant EV chargers from a wide range of manufacturers on the market.
