Kilowatts measure charging speed. Kilowatt-hours measure the energy delivered. A plain-English explainer with a conversion table for sizing depot charging.

How batteries, EV chargers and generation get aggregated into one dispatchable grid asset, and why fleet depots are ideal candidates.

Depot charging means charging fleet vehicles centrally at a home base between shifts, not at public chargers. How it works, and how to plan power for it.

Group charging shares one power supply dynamically across many chargers, so a depot can run more bays without a bigger grid connection.

HGV charging needs far more power and much bigger batteries than car charging. Here's what UK fleets need to plan for.

Dynamic load balancing monitors a site's total power draw in real time and adjusts EV charging speed automatically, avoiding trips and grid upgrades.

Tariff management schedules EV charging into cheaper electricity price windows automatically, so charging finishes on time without paying peak-rate prices.

Load management balances EV charging against a site's other electricity loads so total demand never exceeds the available grid connection.

Vehicle identification lets a charger recognise the connected EV's unique ID over the charging cable, enabling Plug & Charge and per-vehicle billing.

Solar-compatible chargers prioritise on-site solar generation for EV charging before drawing from the grid, cutting cost and grid dependency.

Intelligent charging schedules and adjusts EV charging around tariffs, site load, or grid signals instead of running at full power the moment a cable is plugged in.

ISO 15118 is the international standard for digital communication between an EV and a charger, enabling Plug & Charge and future bidirectional charging.

OCPP is the open standard that lets chargers from different manufacturers connect to the same management platform for monitoring, control and billing.

OTA updates push new firmware to a charger remotely over its network connection, so new features and fixes arrive without a site visit.

V2G lets energy stored in an EV battery flow back to the electricity grid, turning the vehicle into a distributed energy resource that can earn revenue.

V2H lets an EV's battery power a home's electrical circuits directly, typically used as backup power during an outage or to avoid peak-rate electricity.

V2L lets equipment plug directly into an EV's battery via a standard socket, powering tools, camping gear, or emergency backup without any grid connection.

A BESS stores electricity for later use: peak shaving, backup power, EV charging support, and energy arbitrage.

Energy arbitrage means buying electricity cheap and selling or using it when it's expensive. Here's how battery storage and automated trading make it work.

DC fast charging bypasses a vehicle's onboard charger to deliver power directly to the battery, cutting charge times from hours to minutes.

Overnight charging is a long, low-power top-up between shifts. Opportunity charging is a short, high-power burst during the day.

Fleet electrification means replacing diesel or petrol vehicles with EVs across an operator's fleet. What drives it, and the roadmap that works.

EV fleet TCO covers every cost of running electric vehicles over their life, not just the purchase price.

A CT meter clips onto a site's incoming power supply and measures total electrical load in real time.

Peak shaving cuts a site's highest demand spikes, usually with battery storage, to lower demand charges.

A demand charge bills a site for its single highest power draw in a period, not total energy used.

Behind-the-meter assets sit on the customer's side of the utility meter, like on-site batteries and EV chargers.

UK government support for grid upgrades that enable rapid EV charging at motorway service areas and strategic locations.

A UK government grant covering part of the cost of installing EV chargers at commercial and depot sites.

CCS combines AC and DC charging pins in one connector, and is the standard fitted to nearly every EV, van, bus, and HGV in the UK and Europe.

An EV's charging curve shows why charge speed isn't constant: it peaks mid-charge and tapers near full.

State of charge (SoC) is a battery's remaining energy as a percentage of full capacity.

Round-trip efficiency is the share of energy a battery returns after a full charge-discharge cycle.

C-rate describes how fast a battery charges or discharges relative to its total capacity.
