Diamond Electric Develops "3 in 1" 6.6 kW Onboard Charger
OSAKA, Japan, Nov. 19, 2020 /Kyodo JBN-AsiaNet/ --

- Integration of Multiple Systems Seen Contributing to Spread of EVs -

Diamond Electric Mfg. Co., Ltd. announced on November 19 that it has developed 
a "3 in 1" onboard charger (OBC) which integrates into one package the 
following three functions: a 6.6 kW charger, a 2.1 kW low-voltage DCDC 
converter (LDC) for auxiliaries, and a power delivery unit (PDU) to switch into 
fast charging. This feature enables system-level downsizing, reducing the 
weight of electric vehicles (EVs and PHEVs) and expected to contribute to the 
spread of EVs.


As a countermeasure for global warming, EVs and PHEVs are spreading worldwide 
as CO2 reduction becomes more significant. EVs and PHEVs adopt more electronics 
components such as OBCs, and demand for downsizing and weight reduction of 
those components is growing.

In response, Diamond Electric has developed a "3 in 1" 6.6 kW OBC. The 
company's transformer design and thermal management enabled the 30% downsizing 
of the product compared to the existing products (*1) (*2). Furthermore, the "3 
in 1" feature of the OBC, LDC and PDU integration into one package can 
substantially reduce the size and weight in the vehicle system and reduce the 
number of electronics components in EVs.
