Embodiment Construction

[0018] Embodiment of battery management system wake-up system

[0019] Such as figure 2 As shown, the battery management system wake-up system includes a DC / DC converter and a battery management system. The invention of the wake-up system lies in the DC / DC converter, which includes a DC / DC power unit, which is the most basic component of the DC / DC converter and is composed of power tubes to realize on-off Function and voltage transformation function, the power battery is connected to the battery management system through the DC / DC power unit to supply power for the battery management system. Since the DC / DC power unit belongs to conventional technology, this embodiment does not describe the power unit in detail, and the power battery can also be connected to other vehicle-mounted equipment through the DC / DC power unit, such as monitoring equipment GPS, etc. A part also does not belong to the protection point of the present application, and will not be described in detail in...

Abstract

The invention relates to a battery management system wake-up system and a DC / DC converter. Except for a power unit, the DC / DC converter also includes a control module which is connected to a battery management system and controls and connects the DC / DC power unit. When the battery management system needs to be woken up, the control module controls the DC / DC power unit to be turned on, so that a power battery can supply power to the battery management system. Otherwise, the control module controls the DC / DC power unit to be disconnected, and then the power battery does not supply power to the battery management system. The battery management system wake-up system can reduce the software and hardware cost of the battery management system and can improve the operational reliability of the battery management system. Besides, the DC / DC power unit does not need to work for a long time, so that the service life of the DC / DC power unit is prolonged, and as a power line between the DC / DC powerunit and the battery management system is no longer charged for a long time, the potential safety hazard for the whole vehicle can be reduced.

Description

technical field [0001] The invention relates to a battery management system wake-up system and a DC / DC converter. Background technique [0002] With the continuous improvement of the national new energy policy, the market ownership of electric vehicles continues to increase. While the sales of electric vehicles continue to increase, passenger car, car manufacturers and power battery manufacturers are concerned about the safety, reliability and energy saving of power batteries. It is also constantly optimized and improved. In order to meet the timing wake-up mechanism of the power battery system, it is currently working through the high-voltage to low-voltage DC / DC constant-time working mechanism. Such as figure 1 As shown, the power battery supplies power to the battery management system (BMS) through high-voltage to low-voltage DC / DC, specifically, the power unit in the DC / DC converter supplies power to the battery management system. The battery management system is provi...
