Abstract

The invention provides a new energy automobile double-source output power battery pack. The new energy automobile double-source output power battery pack comprises a power battery module, a starting power source module, a bidirectional DC / DC (direct current / direct current) module and a battery management module, which are all arranged in one power battery pack box; the power battery module is electrically connected to the high-voltage end of the bidirectional DC / DC module; the starting power source module is electrically connected with the low-voltage end of the bidirectional DC / DC module; thebattery management module is used for detecting stored energy of the power battery module and the starting power source module; when the stored energy of the power battery module is lower than a first preset value and the stored energy of the starting power source module is higher than a second preset value, the battery management module controls the bidirectional DC / DC module to discharge electricity from the starting power source module to the power battery module to achieve rapid charging of the power battery module with the starting power source module.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and more particularly relates to a dual-source output power battery pack for new energy vehicles. Background technique [0002] In the design and manufacture of new energy vehicles, because the whole vehicle consists of a large number of sensors, power systems (power battery, drive motor, motor controller) and vehicle accessories (PTC, air conditioner, oil pump, air pump, T-BOX, VCU, BMS) , BCM, etc.) and other electrical components, these electrical components all require rated 12V, 24V and other low-voltage power supplies as starting and working power supplies, so the vehicle needs to install a starting power supply as the vehicle's low-voltage power supply source. The vast majority of the market uses lead-acid batteries as the starting power source. The starting power supply requires the DC / DC module to be integrated inside the distribution box or arranged on the vehicle separatel...
