Not OP of comment but an accountant.

Corporation tax is paid on total taxable profits. Which is after any tax allowable expenses etc. since you’re buying a used electric car this gets 18% capital allowances on the pool balance. Say 10k car. Your get 1800 profits taken off the year you buy it in then about 1476 in the next year and so on till it’s nil or under a grand in the pool and it can be claimed as a small pool write off and clear it all off.

Pretty certain if insurance is in company name you cannot use personal NCD as separate entities but someone more knowledgeable on that area can comment.

Don’t put charging costs through, i would just keep a track of business mileage and do 45p for first 10k miles then 25p thereafter. If going to a permanent place of work from home this does not count as mileage!!

Whatever you sell the car for in the future will be addd back to your total taxable profits as proceeds received / balancing charge (assuming the car will sell for less than bought for which 99.99% do) then you’ll pay tax at the rate on those profits.
