The Chevrolet Volt CoolingHeating Systems ExplainedadpostadThe Chevy Volt is equipped with four fully independent cooling systems or loops. The power electronics cooling system loop is dedicated to cooling the battery charger and the power inverter module. The battery cooling system cools or in some cases heats the 3. V high voltage battery. The engine cooling system and heater loop is specific to cooling the gasoline engine and when required, provides heat for the passenger compartment. The electric drive unit cooling system is designed to cool the two motor generator units and electronics within the 4. ET5. 0E drive unit transaxle, and provides lubrication for the various gears, bearings, and bushings. All four systems each utilize their own separate radiator or rad partition for heat exchange, and are sandwiched together and mounted in the traditional location at the front of the engine compartment. These radiators and internally routed coolants are primarily cooled by undercar airflow directed by an air dam, through the radiators. Airflow is augmented by a pair of variable speed, electrically powered 1. V cooling fans controlled by the Engine Control Module ECM. Within all but the electric drive unit cooling system, a precise mixture of premixed Dexcool coolant is used as a heat transport medium. The electric drive cooling and lubrication system utilizes Dexron VI. WarningDue to potential issues with high voltage safety, the Chevy Volts engine cooling, heater, power electronics and battery cooling systems should only be serviced by a qualified factory trained Volt technician. Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the surge tank pressure cap even a little they can come out at high speed. Never turn the cap when the cooling system, including the surge tank pressure cap, is hot. Install 7Zip Without Admin'>Install 7Zip Without Admin. Wait for the cooling system and surge tank pressure cap to cool if you ever have to turn the pressure cap. Patch Dirt 3 Ps3 3 55 And Older there. You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine. The electric cooling fans under the hood can start up even when the engine is not running and can cause injury. Keep hands, clothing, and tools away from any underhood electric fan. WOT Says When topping up or replacing coolants, always use pre mixed Dexcool coolant and NEVER add regular green anti freeze or tap water to ANY of the Volts cooling systems. This premix coolant available at your GM dealer is essentially a 5. GM Dexcool or other GM6. M compliant coolant and filtered low silicate, deionized water. The use of deionized water in hybrids, EREVs, and EVs is a necessity to ensure high voltage isolation and to prevent the internal corrosion of cooling system components. The Power Electronics Coolant Loop. The power electronics coolant loop is designed to ensure the main underhood electronics do not overheat during use. The Power Inverter Module PIM utilizes high power Insulated Gate Bipolar Transistors IGBTs in order to convert DC current from the high voltage battery into 3 phase AC motor drive signals for the motor generator units. These same devices also convert AC to DC for charging operations during regenerative braking. The normal operation of the IGBTs creates a significant amount of heat. The plug in battery charger also rectifies 1. It is essential that the heat developed by these devices while operating the Volt or when plugged in be dissipated in order to prevent damage to the components. The Chevrolet Volt uses a high flow 1. PIM, and the and then back to the pump. The power electronics cooling system radiator is the upper half section of a dual radiator assembly that is common with the high voltage battery cooling system. The power electronics cooling system also uses an air separator device to prevent air bubbles from affecting cooling performance and utilizes a surge tank that acts as a coolant reservoir, and facilitates the routine addition of coolant via a pressure cap. See arningsThe Hybrid Powertrain Control Module 2, controls the coolant pump as well as radiator fan speeds based on a temperature sensors mounted in the radiator. To operate the fans the HPCM2 communicates a FAN SPEED COMMAND to the Engine Control Module ECM via the GMLAN DWCAN network. The electronics coolant pump will be activated whenever the Volt is ON and during 1. VAC plug in charging. The High Voltage Battery Cooling Heating System. The Volts T shaped Lithium Ion battery 3. V is mounted underneath the car and runs down the center tunnel and beneath the rear seating positions. A pair of quick coupler fittings create the coolant INOUT connections to the high voltage battery housing. I/51xOWXJcmlL._SR600%2C315_PIWhiteStrip%2CBottomLeft%2C0%2C35_PIStarRatingTWO%2CBottomLeft%2C360%2C-6_SR600%2C315_ZA(6%20Reviews)%2C445%2C286%2C400%2C400%2Carial%2C12%2C4%2C0%2C0%2C5_SCLZZZZZZZ_.jpg' alt='Fundamentals Of Signals And Systems Third Edition Solutions' />Inside the battery housing there are thermal passages that permit coolant to flow in between the Lithium Ion battery cells. These passages permit the cells to be cooled or heated depending on operational requirements. The coolant inlet to the battery housing includes a debris filter, and a variable high voltage heating element that operates directly off the 3. V Lithium Ion battery, and able to accurately heat the coolant when the battery cells are too cold. As mentioned previously, the battery cooling system shares a radiator assembly and twin 1. The lower section of this dual radiator is used for battery system cooling. The battery cooling system has its own 1. There is also an AIR separator and surge tank that is integrated with the electronics reservoirtank a single housing but with 2 separate tanks. The Hybrid Powertrain Control Module 2 and other networked modules monitor ambient conditions, the battery INOUT coolant temperatures, various Li Ion cell temperature probes, as well as refrigerant temperatures and pressures to establish battery heating or cooling requirements. The HPCM2 will then selectively turn the coolant pump ON or OFF, positions the coolant flow control valve, and depending on whether cooling or heating is required, request either the electric AC compressor to operate cooling, or turn ON the high voltage battery heaterheating. The battery coolingheating system can be activated when the vehicle is ON and if necessary during charging operations. As shown in the diagram, when battery HEATING is required the 3 way coolant flow control valve will be in position A and permits fast heating of the Lithium Ion cells to quickly permit them to attain a desirable operating temperature in cold weather. Position B will be commanded whenever the Li Ion battery cells are too hot. By operating the electric air conditioning compressor, R 1. A refrigerant will be throttled by the thermal expansion valves and permit super cooling of the battery coolant as it passes through the chiller unit. During more temperature stable operating conditions, the flow control valve will typically be commanded to position C circulating the flow of battery coolant out to the battery cooling radiator and back to the pump. This route permits temperature stability by controlling cell temperatures through pump control. The Engine Cooling System and Heater Loop. The engine cooling system and heater loop uses the engine radiator, two 1. V variable speed radiator fans, an electric coolant heater pump 1. V, a coolant flow bypass valve, a high voltage 3.
