The BC-TC range is a series of highly programmable modular battery chargers. The units are available in 10kW, 16kW, 20kW and 32kW modules. Up to 64 modules can be arranged in series, parallel or matrix array configurations to 2MW. Each module is able to operate independently, so that systems can be reconfigured, expanded or broken up to charge different sizes of energy storage devices.

Constant voltage, current and power operating modes are provided. Remote sense is a standard feature which allows users to compensate for the voltage drop in long load lines. All regulation, monitoring and communication tasks are conducted by high performance micro-controllers and digital signal processors. This provides exceptional accuracy and long term stability.

These chargers can be fitted with front panel control and an LCD display. Analogue and RS-232 interfaces are provided as standard. GPIB, RS-422, USB and CAN are optionally available. An easy to use, stand alone software program is also included. LabVIEW and C/C++ is supported by reference libraries provided. A host of protection features allows the output relays of the BC-TC to be automatically activated when specific conditions are met, protecting the battery from any potentially damaging conditions.

Reverse Polarity Protection (RPP) is recommended for energy storage devices without a pre-charge circuit. With the BC-TC energised but output off, the RPP senses the voltage of the connected energy storage device. A contactor is closed after matching the voltage, to prevent large inrush currents and arcing on start up.

An optional embedded function generator allows exact DC waveforms to be implemented at user defined time for pulsed charging. The technique is thought to improve battery discharge capacity and help facilitate longer cycle life.

A special ruggedised variant of the BC-TC is available. The charger operates from an AC generator and provides a DC output. The unit can withstand up to 30g of mechanical shock across X, Y and Z axes. The system operates from temperatures as low as -10°C all the way up to 55°C. Common applications areas include surface boats, submarines and military vehicles.
