On-Board Battery Charger

However, the accumulation of fossil fuel waste has brought about rapid changes in the earth's environment, not only generating air pollution and acid rain, but also causing ecological havoc due to global warming, affecting the health and lives of all species on earth.


 


With the rise of global environmental awareness, more and more countries are demanding a reduction in the use of fossil fuels, which has led to the conversion of many transportation vehicles and large machines to electric power supply. Such equipment must have built-in on-board battery chargers to facilitate the charging of equipment at any time. Currently, electric cars, electric buses, electric boats, industrial/mall dust collectors, floor scrubbers, unmanned trucks, electric forklifts and other tools are common.


 


The full name of On-Board Battery Charger (OBC) refers to the charger that is fixed on the electric equipment. The charger can dynamically adjust the current or voltage parameters when charging the equipment based on the information provided by the internal Battery Management System (BMS) to perform The charger dynamically adjusts the current or voltage parameters during charging and performs the corresponding actions to complete the charging process.


 


Because the vehicle-mounted battery charger is directly installed in various large electric vehicles or industrial equipment, its work is often in a dirty, humid and upside down environment, so the built-in charger needs to have a waterproof, dustproof and shockproof design, and it is recommended to select products that meet the IP65 rating or above to reduce the charging failure rate of the equipment.


 


When selecting a vehicle-mounted battery charger, customers can discuss with a battery charger manufacturer who has the ability to develop products that meet the specifications of input current, output wattage, and output voltage of the device, depending on the needs of the end-use device. A quality on-board battery charger must also consider whether it has the following conditions:


 


Adjustable output voltage

Temperature/voltage/current monitoring design

Heat sink design according to the working environment (fanless natural heat sink, air-cooled heat sink design or water-cooled heat sink)

High power conversion efficiency

Unidirectional and three-way voltage input design options

High-speed CAN network communication with BMS (to determine the correct battery connection status; to obtain battery system parameters, and to obtain instant information about the whole battery and individual batteries before and during charging)

Multi-protection circuit design : Input over-voltage / under-voltage warning / input over-current / output over-current / output short circuit / charging over-temperature

Multi-stage charging curve : Automatically adjust the charging current dynamically according to the battery information from BMS.

Automatically determine whether the charging connector and charging wire are properly connected.

Wire and body with flame retardant function
