Problems solved by technology

[0003] However, the selection of battery cells and the way of grouping are limited, and the voltage after series connection should meet the voltage range requirements of the power system; and the output voltage of the power battery pack is in a linear range, so that the motor controller cannot always work in the most efficient area. Increased energy consumption; when charging, the output voltage of the charging device must meet certain conditions, otherwise it may cause the situation that it cannot be charged or not fully charged, and the applicability is poor

Abstract

The invention discloses a power battery package of a vehicle and the vehicle with the power battery pack. The power battery package comprises battery packs, a DC voltage conversion module and a controller, wherein each battery pack comprises a plurality of single batteries; the plurality of single batteries are connected in series and / or in parallel; and the controller is connected with the battery packs and a DC / DC module separately, provides the vehicle with electricity through the DC voltage conversion module during discharging, and charges the battery packs through the DC voltage conversion module during charging according to a charging request of the power battery package. According to the power battery package, the battery packs and the DC voltage conversion module can be flexibly controlled to work through the controller, so that the applicability and the reliability of the power battery package are effectively improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle power battery pack and a vehicle having the same. Background technique [0002] In related technologies, according to the output voltage range of the vehicle power system, the platform voltage range (for example, the characteristics of other high-voltage electrical components such as motor controllers and air conditioners) and energy requirements, a single battery with a suitable type and capacity is selected. Cores are connected in series and parallel into groups. [0003] However, the selection of battery cells and the way of grouping are limited, and the voltage after series connection should meet the voltage range requirements of the power system; and the output voltage of the power battery pack is in a linear range, so that the motor controller cannot always work in the most efficient area. Increased energy consumption; while charging, the output voltage of the c...
