I don't think that's bad really. Seems practical if you consider just this data.
But obviously, if the energy isn't transferred suitably in the engine and blows up your engine instead, it's useless.
Let's do a comparison, as it touches one of the cores of the problem.

A Hyundai Ioniq electric has a 28 kWh battery and a range of over 200 km.
So it has 5 times the range from less than 3/5 of the capacity.
The running costs on electricity alone would be just 12% of your setup.
In other words, yours is 8 times as expensive to run.

If you have a battery the best way to transfer the power within to motion is by using an electric motor and motor controller. The efficiency of that is typically way above 50%.

And it would be fun.
I've driven all kinds of vehicles on gas, diesel, hybrid and electric. Of those the EVs were by far the best when it comes to comfort and power delivery (no gear changes, instant delivery, constant torque, very fast acceleration).

The thought you would have a big battery on board and just use that to make a diesel engine tick over goes against logic. Like if in the time of the first real cars you'd build a mechanical horse to pull carts instead.
