Diamond Electric Develops "3 in 1" 6.6 kW Onboard Charger

OSAKA, Japan, Nov. 19, 2020 /PRNewswire/ -- 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.

Notes:
(*1) As of October 2020, investigated by Diamond Electric
(*2) Calculated by the enclosure size excluding connectors
