Re: Electric Ford Transit - How will this work?

Well, let's do some maths ...
68kWhr battery into 300km implies a consumption of 0.226kWh per kilometre (which sounds about right).
Doing 600km per week suggests a power consumption of 136kWh per week. Plug in your current electricity bill rate (mine is $0.20 per kWh) and this comes up with a fuel bill of $27.2 per week. Given that this cost is relatively fixed, the employer might choose to simply give one an extra $30 weekly pay. But, I am sure unions will come up with something creative.
As an aside, the diesel is around 10l/100km. Assuming 600km per week (60 litres of diesel), currently around $2 per litre, gives a fuel bill of $120 per week.
As for recharging, a standard socket outlet gives 2.3kWh. Assuming that the vehicle is sitting in the garage 10hrs per night, this gives around 23kWh of recharge per night.
Assuming 600km per week implies a daily run of 120km, which needs 26.4kWh (say 27kWh to keep the maths cleaner).
Running through a weekly recharge schedule ...
Monday morning, fully recharged (over the weekend), capacity is 68kWh.
Monday evening, the battery capacity will be 68-27kWh = 41kWh.
Tuesday morning, the battery has recharged by 23kWh. The battery capacity will be 41+23= 64kWh.
Tuesday evening, the battery capacity will be 64-27=37kWh.
Wednesday morning, the battery has recharged by 23kWh overnight. The battery capacity will be 37+23=60kWh.
Wednesday evening, the battery capacity will be 60-27=33kWh.
Thursday morning, the battery has recharged overnight by 23kWh. The capacity will be 33+23=56kWh. Thursday evening, the battery will be 56-27=29kWh.
Friday morning the battery has partially recharged overnight by 23kWh. The capacity will be 52kWh. By Friday evening the battery capacity will be 25kWh.
Assuming the vehicle has some down time over the weekend, it will need around 19 hours to fully recharge.
As for recharging in the home, yes, I agree that a significant proportion of the population does not have ready access to an additional power outlet for EV recharging or even space in the yard / unit complex. Reading through the information on the Ford web site, it appears that the vehicle will take 42kWh of charge in just over 30 minutes at a fast charging site. Might have to try and slip a charge in over lunch or smoko.
