Any standard battery charger can charge a battery and it will charge it to the point where boiling will take place. Our system is unique in that it will maintain the batteries and determine and adjust the state of a battery at any given time. Each panel will control the battery state of up to 255 charging systems. The system is completely controlled by a PLC with touch panel HMI. As it is part of a normal vehicle storage regime to run engines periodically, we will also design, manufacture and install an exhaust extraction system for the vehicle storage building.
