EVAL_2KW_48V_CHAR_P7 48 V lead-acid/Li-ion battery charger 2 kW high efficient natural convection cooled evaluation board based on CoolMOS™ P7
The 2 kW lead-acid / Li-ion industrial battery charger targets LSEV applications. The evaluation board uses a dual-boost PFC + half-bridge LLC power supply solution. Infineon’s latest CoolMOS™ P7 Superjunction MOSFETenables natural convection cooling. The design has a battery management control system capable of charging both lead-acid and Li-ion based 48 V batteries in the different charging modes. The charging profiles correspond to the latest trends of battery charging. Furthermore, the evaluation board offers the possibility to set the nominal battery capacity in order to adjust the charging currents of different battery sizes. In addition to this, it grants a parallel operation of two modules that can extract 4 kW maximum charging power. This enables fast charging for Li-ion batteries.
The 2 kW evaluation board is designed to operate at a wide range input from 90 VAC up to 265 VAC to charge lead-acid and Li-ion batteries of 48 VDC. The charger also gives the possibility for a battery capacity selection (from 40 Ah up to 250 Ah). The design comes with an integrated error indication and handling system. It is programmed not only to de-rate output power at PCB temperature of 105°C and shutdown at 115°C, but it also adopts the charging profile by sensing the battery voltage and temperature.
Furthermore, the design can be modified to support higher output voltage (72 V and 144 V). For detailed information, please refer to the application note.
