Intelligent multi-type battery hybrid energy system and energy supply method

Abstract

The invention relates to an intelligent multi-type battery hybrid energy system and an energy supply method. The system comprises a plurality of energy batteries, a power battery, a high-voltage power management and distribution module and a plurality of current conversion assembly control modules, and the power battery is provided with an output control module used for controlling the output power of the power battery; the output control module is connected with the high-voltage power supply management and distribution module, the energy batteries are connected with the commutation assembly control modules in a one-to-one correspondence manner, the commutation assembly control modules are connected with the high-voltage power supply management and distribution module, the high-voltage power supply management and distribution module and the power batteries are connected with the motor power system, and the current conversion assembly control modules are connected in parallel. The method comprises a vehicle driving function method and a single-energy battery high-power function method, and has the advantages that different endurance requirements can be met, so that the electric vehicle has long endurance and high power; and a battery changing mode and a charging mode coexist, so that energy supplementation is facilitated; Various types of energy batteries can be compatible; and vehicle power is not affected by the number of energy batteries.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an intelligent multi-type battery hybrid energy system and an energy supply method. Background technique [0002] At present, the new energy vehicles on the market mainly consist of the following types. The first type is a single-cell battery fixed non-replaceable battery; the second type is a single-cell battery-chassis battery-replacement mode; the third type is a single-cell modular battery replacement mode ;The first two types of modes are based on a single energy storage battery for application promotion, and the battery capacity is large, it cannot be divided, and it is impossible to assemble application batteries on demand; the third mode, already under the premise of the first two modes, The standard modularization of the battery can realize the application of a single battery type covering multiple models, which is more versatile and convenient for battery cascade utiliz...
