Abstract

The invention belongs to the technical field of hybrid vehicles, and discloses a control system and method for a power battery of a plug-in hybrid vehicle. The system comprises: an engine cooling loop which is provided with an engine and a radiator III; a motor cooling loop which is provided with a power motor body and a radiator III; a battery cooling loop which is provided with a power battery, a radiator III and a radiator II; a warm air loop which is provided with a radiator III, a radiator IV and a fan II; an air conditioner refrigerating circuit which is provided with a radiator II, a radiator V and an air conditioner compressor assembly, wherein the radiator V is connected with the fan II; and a passenger compartment, wherein the temperature is adjusted through the fan II. According to the system, an electric heating device of a high-voltage electric component is omitted, the power battery and the passenger compartment are heated under the condition that an engine is not started, and the system cost is reduced.

Description

Technical field [0001] The present invention relates to a control system and method for hybrid vehicles Field, particularly to a plug-in hybrid vehicle battery. Background technique [0002] Plug-in hybrid electric vehicle combines low fuel consumption and a traditional fuel car length advantage continued driving mileage is a necessary transitional product traditional fuel vehicles to new energy vehicle development. However, due to the plug-in hybrid electric and pure with traditional fuel car two drive systems, cost more than traditional fuel vehicles, which limits the promotion and application plug-in hybrid cars. Thus reducing cost is an important means to promote plug-in hybrid's. The cost of hardware plug-in hybrid is basically not affected sales, but may increase the cost of software sales sharply lower. Thus, by software developers to develop alternative control method that is certain hardware features are plug-in hybrid important means to reduce costs. [0003] Plug-in hy...
