Why does the hybrid battery need a cooling system?
The On-Board Charging Module (OBCM), which manages the charging of the high voltage battery pack with an AC current. The combined current draws of these components generate significant amounts of heat, hence the modules’ need for a dedicated cooling circuit.
How is the hybrid high voltage battery cooled?
The HV battery on the Volt uses a single coolant loop with an external coolant chiller (a mini-evaporator connected to the A/C system), and a 1.5 kW internal heater, coolant hoses, cooling manifolds, and cooling plates. These cooling plates have tiny coolant passages.
What happens when a hybrid battery stops working?
If that battery fails, then you could still drive the Prius, but it will be weaker and a lot less smooth. Other hybrid systems that require a 12-volt battery might not work if the hybrid battery dies. Even if your car does start, you run the risk of your car losing power or dying on the road.
Do hybrids need Antifreeze?
The coolant system is one of the most important elements of keeping your hybrid vehicle at peak performance. A hybrid cooling system works similarly to traditional systems, but requires a different type of care because some of these vehicles have more than one system to worry about.
Do hybrids use special coolant?
Cooling Systems Most hybrids have a separate cooling system for the inverter and electric motors/generators in the transmission case. These cooling systems typically have their own electric pump, heat exchanger and special coolant.
What is the average life of a hybrid battery?
80,000 to 100,000 miles
Most hybrid vehicle manufacturers say that, on average, a hybrid battery pack will last from 80,000 to 100,000 miles.
Can a hybrid engine overheat?
The engine compartment may be very hot, causing serious injury such as burns. Wait until the hybrid system has cooled down before adding engine/power control unit coolant. When adding coolant, do so slowly. Adding cool coolant to a hot hybrid system too quickly can cause damage to the hybrid system.
Why does a hybrid car have a fan?
Hybrid cars have a blower fan which blows air through the hybrid battery to prevent it from getting too hot. Heat kills batteries, so it is essential that the hybrid battery gets a supply of air. Over time dust and general junk will build up on the fan, reducing its ability to push air through.
How can I get my battery cooling fan to work?
The fan needing cleaning and a re-flash of a Computer. Try Googling you make model year and Hybrid Battery Cooling Fan. 1 people found this helpful. The fan and duct ware clean. The fan wasn’t working until I swapped the fan relay with another relay. Now the fan runs all the time plus all the warning lights stay on. 1 people found this helpful.
Why do I need to clean my hybrid battery fan?
we highly recommend to perform battery fan cleaning as it prevent battery cells overheating, because fan is the only service item that can affect Prius battery life. based on our experience with Toyota Prius Without proper maintenance the hybrid battery will surely die prematurely
Is the battery cooling fan running on my Prius?
Hybrid battery cooling fan running constantly, lots of warning lights! Discussion in ‘ Gen 2 Prius Care, Maintenance and Troubleshooting ‘ started by Kinsemfarms, Mar 15, 2014 .
