Ford Fusion Hybrid 2015 won't start after a jump start

[qtra]

Hi all, we tried to jump start a Ford Fusion Hybrid 2015 according to this video https://www.youtube.com/watch?v=lp0TLfxu3ws&ab_channel=DURANOUSA-PHILIPPINES

 

The lights turned on briefly for about 1 second without me starting the car. But when I inserted the key into the ignition and attempted to turn it on, nothing happened. The car was completely dead, no sound, no lights, etc. Could it be a starter problem? Are there any other ways to start the car I could try before towing it to a mechanic?

 

Thanks for you help!

The car doesn't have a starter or an alternator.  It is started by one of the high voltage traction motors.

It sounds like a permanently damaged 12 volt battery or a jump starter that is not charged.

All the jump starter has to do is provide enough current to activate the contactors that connect the HVB to the car.

Once connected the DC to DC converter provides the 12 volts to run the car.

At the end of the life of my first 12 volt battery, at 117K miles, all I did was charge it with a 3 amp charger overnight, it started up fine the next morning and I drove it to the Ford Dealer who installed it a new 12 volt battery which is still working fine at 150K miles.  Once it is started, the hybrid system will keep the 12 volt battery charged while the car is on.  

 

These charger and surge starters are designed to supply about 80 amps for a very short time 1-2 seconds, long enough for a conventional non-hybrid car to start one time.  But as Murphy says, you don't need hardly any amps out of the 12 volt battery to start, because the HVB starts the car.  I would not even try one of those surge chargers, I would not be sure how the whole hybrid electric system would respond to that misplaced voltage/amp surge.
