Abstract

The invention discloses a vehicle-mounted battery charger and a DCDC integration method for an electric automobile. According to the method, a battery charger DCDC integration module and a cooling pipe are included. The vehicle-mounted battery charger module and a DCDC module are made into an integrated module through integrated circuit design, and compared with separated type arrangement of an existing vehicle-mounted battery charger and a DCDC module, innovative improvement is achieved. According to the method, the module is controlled through a battery management system (BMS) for power batteries, safety and reliability are achieved, the method is easy to control, the requirements that a high voltage power battery and a storage battery inside the automobile are charged are met, by means of the method, the integral space structure of the electric automobile is greatly saved, and therefore good market application prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle charging, and in particular relates to an electric vehicle on-board charger and a DCDC integration device. Background technique [0002] Compared with traditional fuel vehicles, electric vehicles have incomparable advantages such as environmental protection, energy saving and low noise. Under the background of energy crisis and environmental pollution, electric vehicles have become a research hotspot in all countries in the world, and they are the next round of automobile industry revolution. It is of great significance to vigorously develop electric vehicles for my country to occupy a place in the future automobile industry. [0003] At present, the popularity of electric vehicles is still very low, there are many design defects in various aspects, and the standards are not uniform. The charging devices introduced by some manufacturers are expensive and inefficient. In addition, electric...
