TM4 Expands its Product Offering with the Launch of a Bi-Directional Charger Inverter


In a strategic move to broaden its product offering, TM4 has launched a Bi-directional Charger Inverter, the BCI20. TM4 has developed this product in collaboration with Convertronix, a Quebec-based company specialized in the design and manufacturing of power conversion equipment.

The TM4 BCI20 is a Bi-directional Charger Inverter that functions as battery charger and inverter for use in a variety of electric and hybrid vehicle applications. It is designed to use the full current range from the AC mains as defined in SAE J1772 for a maximum charge power of 18 kW on 240 VAC.

When the vehicle is in use, the charger becomes a dual inverter that can provide two independent three-phase outputs of 9 kVA each to power various AC auxiliary loads.

“The charger combined with two inverter outputs is very beneficial for our customers. It simplifies the vehicle integration by combining multiple functionalities in one box, moving TM4 closer to our one-stop shop approach,” said Eric Azeroual, sales and customer service director at TM4.

The BCI20 satisfies the IP67 rating for reliable operation in harsh under-hood vehicle environments. It allows for a flexible installation in multiple mounting locations due to its compactness and lightness. On the longer run, TM4 aims to expand this new series of product and offer to the North American and European markets both a single-phase and three-phase bidirectional charger inverter in 450 VDC and 750 VDC options.
