Design Considerations for On-Board Battery Charger (OBC)

2020-09-21

In the era of industrial development, humans have extensively used fossil fuels such as coal, oil, and natural gas as the power sources of many tools. However, fossil fuel waste accumulation has brought about drastic changes to the earth’s environment. Not only have air pollution and acid rain resulted, but the ecological catastrophe caused by global warming has affected the health and lives of all species on Earth.

 

With a global rise in environmental awareness, more and more countries are demanding fossil fuel use reductions, which have prompted transportation vehicles and large machines to resort to powered operations. This type of equipment requires an on-board battery charger (OBC) to conveniently charge devices at any time. At present, the common tools include electric vehicles, electric buses, electric boats, industrial/mall dust collectors, floor scrubbers, cargo-carrying robot, electric forklifts, etc.

 

The full name of an OBC is an On-Board Battery Charger, which refers to a battery charger fixed on an electric device. According to the data provided by the internal Battery Management System, BMS, the battery charger can dynamically regulate the current or voltage parameters while the device is charging, execute corresponding actions, and complete the charging process.

 

Since the OBC is directly installed in various large electric vehicles or industrial devices, it is often operated under dirty, humid, and bumpy environments. Therefore, a built-in battery charger should have waterproof, dustproof, and shockproof mechanical designs. It is recommended that products higher than IP65 grade be selected to reduce the device charging failure rate.

 

When choosing an OBC, customers can discuss with battery charger manufacturers who have battery charger design capabilities regarding products that meet the device input current, output wattage, output voltage, and other specifications based on the requirements of the terminal application device. At the same time, whether the following conditions are met should also be taken into consideration:
