Electric Vehicle (EV) Glossary

Share on


The Advisory Electricity Rate (AER) is a government-set tariff that businesses can use to reimburse employees for their EV energy usage. Currently, the rate is 5p per mile.


An Advisory Fuel Rate (AFR) is proposed by the government for businesses to use when reimbursing their employees for their fuel usage whilst driving a company car or commercial vehicle, or when a business requires reimbursement when employees use a company vehicle for private use.


Battery Electric Vehicle - further shortened to Electric Vehicle - run on battery power as opposed to an Internal Combustion Engine (ICE) found in petrol/ diesel vehicles.


Benefit-in-Kind is a tax payable by employees when they receive benefits from their employer, on top of their salary. A company car used for private and work purposes is liable to Benefit-In-Kind. Once the tax has been worked out, the amount owed is usually taken in monthly instalments from wages through Pay as You Earn (PAYE).

Bill shock

Bill shock is an issue that occurs with reclaiming the cost of home charging. When an employee gets an EV and starts charging at home, their direct debit amount is unaffected. It isn’t until further down the line that their increased consumption is taken into account that their direct debit amount increases. By this time, it’s likely that the reimbursement from the employer has been spent by the driver. 


Track, analyse and reduce your business carbon footprint with our unique carbon reporting tools. Through the charging data we hold in the Mina Fleet Portal, combined with our integration with the National Grid, we’re able to show the true carbon intensity and emissions produced for each charge. This information can be seen in ‘real time’ on the Mina Fleet Portal, broken down by employee, or visualised across the entire business and is available for download in our set of reports on a monthly basis. 

Charge points

Charge points refer to the locations EV drivers can go to charge their cars in public. Mina has the largest dedicated network of charge points in the UK, so EV drivers will have access to a choice of charge points close to their location.


Mina Chargepass® is the UK’s largest public roaming network, dedicated to businesses. Part of the Allstar network alongside the InstaVolt network, our single RFID card gives employees access to thousands of public charge points across the UK. The best thing, employees don’t pay a thing. Instead, Mina issues one monthly invoice to the business for all charging costs and makes accurate payments direct to suppliers.

Company car

Although self-explanatory, a company car specifically refers to an employee who drives a car provided by their employer as a perk, as opposed to using the car exclusively for work purposes.

Commercial vehicles

These are vehicles that haul at least one tonne of cargo for business purposes. This includes lorries, vans, tractors, pickup trucks, and “car-derived vans”. They are also exclusively used for work purposes as opposed to being an added perk for driver's personal use.

Expense claims

Expense claims are requested by employees who want to be reimbursed for work expenses they have personally paid out for. This could be for food or travel, but most likely, fuel and electric charge costs.

Energy crisis

Also referred to as an energy shortage, an energy crisis means a considerable lack of available natural energy resources to an economy, for instance, petrol/diesel.

Energy price cap

A price cap is the maximum unit price a supplier can charge for their resources, for instance, energy suppliers can not exceed the price cap when charging their consumers for their energy usage.

Energy supplier

An energy supplier refers to the company that provides energy to a driver's home. It’s also where payments for energy consumption should be sent, for example, Shell Energy, EDF or E.ON Energy.


EV is the short-form version of ‘electric vehicle’.

Fleet Approved®

The Mina Fleet Approved® scheme highlights charge points which perform well in a business setting, evaluating a number of factors: Ease of install (E.g. need for separate earthing protection, important given large fleets may be installing hundreds of home chargers), quality of and frequency data (Mina compatibility, strength of internet connectivity, storage and accuracy), smart charging features (to ensure charging for lowest cost and lowest carbon), service (strong support if things go wrong).


Fleets refer to the range of vehicles a business may have. A fleet could be as little as two company cars/ vans up to 1000s.

Fleet Portal

See costs, consumption and carbon for every charge in our easy-to-use dashboard. Have workplace and home charge points too? Our Portal lets electric fleet managers compare the mix and cost of charging across home, workplace and public for each driver.


Hybrid Electric Vehicles use a combination of an internal combustion engine and an electric motor that draws power from a battery to operate. However, HEV users charge their batteries through regenerative braking, unlike other electric car users.


A Hybrid electric vehicle is powered by both an Internal Combustion Engine and an electric motor. A hybrid can’t be plugged in to charge like a fully electric vehicle, instead, the battery is charged whenever the driver breaks as well as through the ICE engine.

Home charging

Exactly what it sounds like, charging your electric vehicle at home with a charge point installed on your property. This is usually classified as the most efficient and cheapest method of EV charging.


Mina Homecharge® is the UK’s only solution which pays for employees’ charging costs accurately at home, direct to supplier. We integrate with employees’ home chargers and energy suppliers to calculate the exact cost of charging their company EV at home. Employees don’t pay a thing. Instead, Mina issues one monthly invoice to the business for all charging costs and makes accurate payments direct to each employee’s energy supplier. 


Internal Combustion Engines can be found in most road vehicles that run on petrol/ diesel in any capacity. They can be found in Hybrid vehicles too, and work by burning whatever fuel the vehicles use with air, generating power.


This is simply the umbrella term used for the installation process for electric vehicle charge points, whether at home, in public or workplace. We know installing hardware at employees' homes can be a complex process, but it doesn't have to be. Mina makes it simple by offering full coordination of installing EV chargers, Mina Fleet Approved™ hardware, prices from as little as £812 per charger and a no obligation free quote.


A kilowatt hour (kWh) is the measure for the amount of energy used within an hour, specifically, electricity. 

Large fleets

This definition of a large fleet isn’t set in stone, however, a fleet with more than 50 company cars/ commercial vehicles would usually fall within this category.


Mild Hybrid Electric Vehicles host an electric motor, however, unlike a normal hybrid vehicle, the motor doesn't drive the car, it only supports the combustion engine.


That’s us! Mina was founded to accelerate the transition to electric vehicles by making paying for EV charging radically simple. Offering a range of EV charging payment solutions, including Mina Homecharge®, Mina Chargepass® and Mina Workplace® as well as our other offerings like Carbongrid® and FleetAprroved™ there’s something for every EV fleet.

One Fleet®

Mina One Fleet® subscription service offers businesses Mina Homecharge®, Mina Chargepass®, Mina FleetApproved® hardware and installation, ongoing service and maintenance of hardware plus the option to charge in public, for free, during any hardware downtime periods - All for a fixed monthly fee per driver. This product is NOT available through Mina’s trusted reseller or introducers.


A Plug-in Hybrid Electric Vehicle improves on normal Hybrid vehicles. They have an electric motor as well as an Internal Combustion Engine. This lowers gas usage and enables the battery to store enough energy to run the electric motor.

Public charging

For EV drivers who don’t have off-street parking or just find that they need to charge on the road, public charging is the way to do so. There’s an ever-expanding amount of locations across the UK where electric vehicle drivers can park up to top up.Range anxiety - A driver looking into purchasing an electric vehicle may be worried about the distance an EV can go before running out of charge. Most EVs have a considerable range now, and this will only increase as technology advances. 

Rapid charger

Rapid chargers can charge electric vehicles very quickly. There are two types of rapid chargers, AC and DC. AC chargers speed up charging by using more power. DC chargers, or ultra-rapid chargers, offer an even faster charging speed, significantly reducing charge times.


To reimburse someone is to pay them back for the money they are owed. In this case, EV drivers would be reimbursed by their employer for charging costs. Mina, however, bypasses the need for employers to do this. Mina Homecharge®, Chargepass® and Workcharge® DONT reimburse drivers, instead, they roll all changes made by drivers into a monthly invoice that is paid directly to drivers' energy suppliers, therefore, drivers never have to pay a thing in the first place, cutting out the risk of them being short-changing, as well as hours of admin.


Radio-frequency identification utilises electromagnetic fields to identify and track tags on objects. Our Mina Chargepass® uses RFID to keep track of each driver's charges, including information such as charge times, locations and even carbon usage.


An abbreviation of small and medium enterprises or businesses. These would be small fleets with fewer company cars/ vehicles, usually less than 49.


Tariffs, or tariff rates, signify the amount a driver's energy consumption will cost when charging their EV. These can fluctuate often, with some even charging more than a few times a day, therefore, a business reimbursing these costs through the AER will likely be short-changing drivers.

Workplace charging

Just as EV drivers can charge at home and on the road, businesses are now installing charge points at workplaces to encourage employees to use EVs, or to support their drivers with charging their work vehicles.


Installing and managing office and depot electric vehicle chargers has never been more simple, now with Mina Workcharge®. Through introductions to our trusted installation and back office partners, businesses can choose from the latest EV smart chargers, OZEV grant funding if qualified, set different charging prices for employee and visitor charge sessions - or offer for free, and easily see employees charging behaviours through RFID authentication.
