Battery Management System - safe and efficient control of lithium battery technology

The BMS ensures a long lifetime, safe handling and high-accuracy State of Charge calculations.

The Battery Management System (BMS) monitors in- and output currents at all times.

Active cell balancing does not guarantee equal charging of individual cells - the BMS from Clayton Power does.

The BMS knows that the difference between a fully charged and nearly empty cell is only 0,125V.

The BMS interrupts charging before any one cell is overcharged.

The BMS knows that the difference between a lithium cell in idle mode and one discharged with 0,5C is only 0,2V.

Most accidents involving lithium batteries happen because of overcharging - the BMS from Clayton Power prevents this.

The BMS knows that values depend on time and temperature.

The BMS automatically reacts to shorts by turning off and restarting to prevent hazardous situations.

The BMS uses complex algorithms to calculate high-accurate State of Charge (SOC) levels.

The BMS monitors internal cell temperatures and detects critical changes.

Through accurate SOC calculations the BMS protects the cells against deep discharge.

All Lithium Ion Batteries from Clayton Power has an integrated Battery Management System. Learn more about the Lithium Ion Batteries ›

At Clayton Power we develop products and systems with integrated computerised Battery Management Systems (BMS) with intelligent chargers as integral parts.


BMS 4C - Battery Management System for lithium battery based power systems.

All the Battery Management System models allow for charge and discharge control of every single cell, cell-temperature control and cell balancing of each single cell in charge, discharge and idle mode.

The Battery Management Systems use a triple security system based on a combination of software and hardware security. 

An integrated MOSFET based safety breaker prevents shorts. CP Battery Management Systems ensure you the safe and convenient use of intelligent lithium battery technology. 

Our BMS models may be configured to alarm signals in case of over- or undervoltage, critical cell temperature, and/or critical charge/discharge levels.
As an extra feature, Clayton Power BMSs are equipped with a diagnostic output system that is accessible via your laptop. It offers you an extensive update on the system, the condition of battery packs, charge cycle statistics, and various other features.
