Embodiment Construction
[0038] The technical solutions of the present invention will be described in detail by the following examples. The following examples are only exemplary, and can only be used to explain and illustrate the technical solutions of the present invention, but cannot be construed as limitations on the technical solutions of the present invention.
[0039] The present application aims at thermal management of a power battery for a hybrid vehicle. When the temperature of the power battery is too low in winter, the waste heat of the engine coolant is used to heat the power battery, so that the power battery can be quickly and actively heated to the full power operating temperature range. When the temperature of the power battery is high, the battery radiator and fan are used to cool the power battery to keep it within the full power operating temperature range.
[0040] The present application adds a battery radiator, a fan, a three-way electronic valve, an electronic water pump, a wat...

The invention relates to a power battery thermal management system and a control method of a hybrid electric vehicle. The power battery thermal management system of the hybrid electric vehicle comprises an engine cooling water jacket, a power battery provided with a cooling water path, a three-way electronic valve, a battery radiator and an electronic water pump. According to the power battery thermal management system of the hybrid electric vehicle, the temperature can rapidly rise to a full-power operation range, so as to avoid that a hybrid system cannot be used normally due to continuous low-temperature; and when the battery works normally, in order to avoid the temperature rising to the area of power reduction, a cooling circuit, including a fan, a radiator and an electronic water pump, is used to cool the power battery, so as to maintain the battery in the full-power operation temperature range and maximize the use of hybrid power.
Description
technical field [0001] The invention belongs to the technical field of new energy vehicles, in particular to a hybrid vehicle power battery thermal management system and a control method. Background technique [0002] On the basis of ensuring the cruising range of traditional fuel vehicles, hybrid vehicles can provide additional power output through power batteries and motors or adjust the operating area of the engine to achieve clean driving and save fuel consumption. [0003] Hybrid vehicles generally have more than two sets of power systems, including internal combustion engines, power batteries, a number of dual-purpose motors for power generation and driving, as well as transmission connection devices and control systems that coordinate the output of each power system. [0004] There are different types of power batteries such as ternary and lithium iron phosphate. Different hybrid vehicles have different requirements on the charging and discharging performance of po...
