Recently, the Avita 11 jointly built by Changan, Huawei and CATL was released online. This model is equipped with Huawei's intelligent electric DriveONE high-voltage on-board charging system, bringing users a safe, reliable, convenient and fast AC charging experience.

Huawei's high-voltage on-board charging system includes an 11kW on-board charger OBC, a 2.5kW DCDC, and a PDU high-voltage power distribution box, bringing consumers a safe and reliable AC charging experience. The high-voltage 11kW on-board charging system can output ultra-high voltage of 480-750V to charge the battery pack. This is also the first product in China that can achieve OBC ASIL B and DCDC ASIL C functional safety levels under high voltage conditions (current industry product functional safety level requirements). Low or even no requirements), truly achieve "high voltage" and "safe" AC charging; and the whole vehicle can achieve "speed compatibility" of AC charging, compatible with AC charging from 3.3kW to 11kW, to achieve more convenient purposes ground charge. Based on the 90kWh battery pack of the Avita 11 model, the 11kW AC charging takes only 8.5 hours to fully charge the battery, and the charging speed is 3.3 times that of the 3.3kW AC slow charging.

Consumers are often faced with car usage scenarios in humid areas and with large temperature differences between day and night. Huawei's in-vehicle charging system is fully equipped with a patented anti-condensation connector, which can achieve "zero" condensation risk of products and ensure safe and reliable charging in humid environments. Thanks to the high-strength explosion-proof design, the product can also withstand the 31% hydrogen explosion test without bulging or explosion, ensuring reliability during charging. And the whole machine adopts multiple signal shielding structure design, reaching the level of EMC LEVEL3 (generally lower than LEVEL3 in the industry), and there is almost "zero" signal interference to the work of other components in the car.

In addition, Huawei's in-vehicle charging system can also bring consumers a convenient and fast power consumption experience. For external power supply scenarios such as camp picnics that consumers love, its high-power inverter function can support V2L external power supply up to 3.5kW, meeting all the power requirements of daily camp electricity. At the same time, Huawei uses higher-precision insulation inverter detection technology to ensure the safety of external power supply and prevent consumers from risking electric shock when using the external discharge function.

Huawei's in-vehicle charging system uses vehicle-grade components in the selection of key components, which can meet the unique driving power supply requirements in strong vibration scenarios. For 12V DC power consumption scenarios, the DCDC-based conversion can provide users with power supply functions such as 2 50W high-power wireless mobile phone charging in the car, on-board refrigerator, and 150W power supply in the front trunk, providing consumers with safe and fast low-voltage power consumption experience.
