For me, my V60 D6 AWD PHEV is more of an electric car, because I have the pleasure of constantly charging it, and a full charge is almost always enough to move between charges. The diesel engine runs so rarely that once I contemplated an interesting inscription from the on-board computer, which said that it was required to start the engine, because fuel is out of date

I recently ran into an incredibly stupid situation: after returning from vacation, I found that the car did not start, just like a normal car. In this case, the battery of the hybrid power plant was fully charged. I didn’t come up with any other solution how to “light the cigarette” and went for help to the service for a booster. As a result, the standard sequence of actions. There is a battery under the hood, in the same place as in all V60s (and S60, S80, XC60, XC70), terminals were installed on this battery, the booster mode was turned on and voila - the car started, just like any ordinary car with an internal combustion engine on board.


And the funny thing in this situation is not at all that a fully charged battery cannot help the battery to start the engine, but that I could not go anywhere. Yes, a fully charged electric car (PHEV stands for a chargeable electric car) did not go anywhere due to insufficient charge of the small "onboard" battery.

Usually, a diesel engine won't even start, it just detects when the start button is pressed, and I start driving on electric traction.

And what do you think happened after "lighting"? Didn't even have to start the engine! The car, having received the required current in the system, simply offered to continue driving on electric traction without starting the engine!


So what's the problem here?

I guess the fact is that the V60 was not originally conceived as a PHEV, this is the most common Volvo station wagon, modified to suit the company's requirements. Those. engineers "attached" electric motors, batteries and the control of this entire system to the most ordinary car. Simply put, a car with a diesel engine and an electric part live separately from each other and, if necessary, can work together, but it is the "classic" part of the car that is responsible for the work.

Of course, in such a situation it was impossible to foresee all the options, I am sure that the Swedes did not even imagine a situation in which the car's "on-board battery" would run out, and the car itself would be fully charged, and if they did, they decided that the owners of such cars will prefer to wait for help. By the way, before self-rescue, I used Volvo On Call. It's funny that the operator had no idea about PHEV and just replied with learned phrases, eventually canceling the request at my request. Unfortunately, you don't have to be an engineer to realize that there are solutions to these kinds of problems. So, for example, the engine control module and the ignition control unit could receive two types of power supply, or it would even be possible to lay an additional circuit to "boost" the "onboard battery" from the main battery.


Now I'm wondering what happens if the car runs out of fuel and the battery is fully or partially charged? Will I be able to get to the gas station or will I have to walk the old fashioned way with a canister? It will be necessary to check somehow.

PS In fairness, after contacting the dealership, the battery was found to be faulty and the "small on-board battery" "went" "for a replacement.
