Dilong Provides On Board Charger Efficient Solutions for EV

On-Board Charger (OBC) is a device that converts AC power into DC power. It is installed in pure electric vehicles and plug-in hybrid vehicles, converting AC voltage from residential power grids or public AC piles into the DC voltage required by vehicle batteries to charge these vehicles.

The output power of OBC varies depending on the configuration of the vehicle, mainly between 2 kW and 40 kW. It can be divided into single-phase and three-phase according to the different input voltages. The standard single-phase on-board charger has a power of 3.3 kW, 6.6 kW, or 11 kW, mainly used in passenger cars, small commercial vehicles, and special-purpose vehicles. The three-phase on-board charger has a power of 11 kW, 22 kW, or 40 kW, mainly used in large commercial and special-purpose vehicles such as buses and trucks.

In recent years, with the explosive growth of the new energy passenger car market, OBC has become an important component of pure electric vehicles and plug-in hybrid vehicles. Why does almost every passenger car need to be equipped with an on-board charger? This is because there are three core advantages.

Increased flexibility and convenience in charging electric vehicles

The advantage of equipping electric vehicles with on-board chargers is that it increases the flexibility and convenience of charging. In addition to using public DC charging stations for charging, vehicles equipped with on-board chargers can also use AC power sockets at home for charging, as well as private or public AC charging stations for charging, increasing the diversity and selectivity of charging.

Charging electric vehicles with on-board chargers is safer

Compared to using DC fast charging with high voltage or high current for about 30 minutes to fully charge the vehicle, the charging method of AC slow charging through OBC is gentler, more friendly to the vehicle battery, and safer during the charging process. In addition, the on-board charger can intelligently adjust the charging voltage and current according to the needs of the electric vehicle, which can minimize battery decay and effectively extend the service life of the battery.

Bidirectional on-board charger enriches the application scenarios of vehicles

With the continuous entry of electric vehicles into thousands of households and the development and application of bidirectional on-board charging technology, the usage scenarios of electric vehicles are becoming increasingly diverse. Bidirectional car chargers can not only convert AC power to DC power for vehicle charging, but also convert DC power from the vehicle battery to AC power, supporting outdoor discharge for load power supply during camping (V2L), vehicle to vehicle charging during rescue (V2V), feedback to the grid when the grid load is high (V2G), and even home power supply (V2H).

Dilong New Energy Technology Hebei Co., Ltd. has been focusing on the research and development, production, and sales of car chargers. After more than 20 years of technological accumulation and precipitation, the Dilong brand car charger has gained a high reputation in the global electric vehicle industry. It can provide highly reliable and high-performance car charger solutions for various types of electric vehicles (micro cars, passenger cars, commercial vehicles, buses, trucks, engineering machinery vehicles), as well as electric boats, yachts, etc. For example, single-phase car chargers with powers of 2kW, 3.3kW, 6.6kW, and 11kW, three-phase car chargers with powers of 11kW, 22kW, and 40kW, 22kW high-power bidirectional car chargers, OBC+DCDC 2 in 1 and OBC+DCDC+PDU 3 in 1 integrated solutions, as well as other customized demand solutions.

Nowadays, for most electric vehicle users, using AC power sockets or AC piles at home or in the office to charge the vehicle at the destination through a car charger is more common and economical. It not only avoids the trouble of queuing up for DC charging stations frequently, but also reduces the damage caused to the vehicle battery by frequent use of DC fast charging.

So the development and progress of car charging technology are of great significance for electric vehicles to enter thousands of households and become a means of transportation for people. Dilong New Energy has always focused on the research and innovation of forward-looking technologies for electric vehicle on-board chargers, committed to providing high-quality on-board charger solutions for global customers and providing sustained value for promoting the rapid development of the electric vehicle industry.
