Abstract

The invention discloses a vehicle power source managing system and an electric vehicle with the same. The vehicle power source managing system is connected with a vehicle control system and comprises an energy storage unit, a current control level connected with the energy storage unit and a controller connected with the energy storage unit and the current control level. The controller comprises a battery managing system and a communication interface connected with the vehicle control system. The vehicle power source managing system is further provided with a change-over switch connected with the current control level in parallel, and the change-over switch is connected with the controller. The vehicle power source managing system guarantees normal operation of a battery under the instant high current output condition, and overcurrent protection is achieved.

Description

Technical field [0001] This application relates to the field of electric vehicles, in particular to a vehicle power management system for electric vehicles and an electric vehicle installed with the system. Background technique [0002] In the prior art, in the field of electric vehicles, lithium-ion batteries are gradually used to replace traditional lead-acid batteries to make energy storage systems (or “batteries”). Generally, the rated working voltage of the vehicle power management system is 6V, 12V, 24V, etc. Compared with lead-acid batteries, lithium-ion batteries are more sensitive to the physical environment and power load conditions. For example, in a low temperature environment, the power input and output capabilities of lithium-ion batteries will be limited by their increased internal resistance. In this case, an excessively high current will cause the critical voltage to exceed or fall below the normal value, which will damage the battery or even damage the battery...
