Charging strategy & the 80-percent rule
Which charging range is kind to the battery, when an HPC stop pays off, and how to plan the sequence — the basics on which every good charging tip is built.
Charging your EV: how it works — the hands-on service for companies
The B2B service at a glance
The four guide areas — Ecosystem & market, Charging tech, Charging & costs, Service — are turned here into an offer for companies: an employee training for your team (fleet, sales, customer advice) and a voucher that you can give to your customers for their new EV. For private EV buyers the hands-on service, of course, also exists — personally, on site or remote.
Employee training: “Charging your EV: how it works”
You run EVs in your fleet, you advise customers on electric vehicles — or you want your sales team to confidently master the topic of charging? The full-day training covers all four LadeGuide topics.
Price range & process
€3,500 per day — the benchmark on which your individual offer is based. We agree with you on scope, the number of participants, and the practical share (e.g. a charging demo on a fleet vehicle), and we document the workload transparently.
Foundational knowledge
Charging types & charging time
AC (wallbox) vs. DC fast charging vs. HPC: output, duration 0–80 % and the fitting plugs (Type 2, CCS2, NACS) — so you can explain it to customers in two minutes.
Understanding the charging curve
Why the charging output does not stay constant: a plateau up to about 80 %, tapering after that — and how to use this to plan charging times and costs realistically.
Stations & cards in everyday life
Station types & operation
Wallbox, DC fast charger, HPC, Supercharger: area of use, typical operation (card, QR code, app) and the stumbling blocks in everyday use.
The German charging network
Charging-point numbers, HPC corridors on the motorway, and what comes to you in 2027 with AFIR — that keeps your company on course.
Charging cards & tariffs
Which charging card fits which driving profile — an occasional driver, a frequent driver, a Tesla vehicle, or ad-hoc? Including roaming logic, so no settlement surprises.
CPO, eMSP & roaming
Who operates (CPO), who sells (eMSP) and who settles? The 8 roles at the charging session — the language that every sales team should understand.
Costs & revenue
Charging costs & cost traps
Idle fees, roaming surcharges, ad-hoc subscriptions: the price ranges of 2026 (AC €0.39–0.59 / DC €0.59–0.89 / HPC €0.79–1.29 per kWh) and the tariff switch that is really worth it.
THG quota & THG premium
Why the oil majors pay EV owners: UBA certification, eligibility requirements, and the real value of the THG premium — around €300 per year and vehicle is generally reachable.
Auditing your EV fleet — optimizing infrastructure & tariffs
A training conveys knowledge. Even more valuable is it when your own charging infrastructure and ongoing contracts are systematically checked for efficiency. The EV-fleet audit analyzes your current fleet and derives concrete optimization steps.
Charging tech & local infrastructure in multi-family residential buildings
Since 1 December 2020, the installation of a wallbox in a multi-family residential building (for tenants § 554 BGB, for owners § 20 WEG) is legally secured: everyone has a claim to consent — the applicant bears the cost. We assess the charging volumes, the types of plug, check the load management, and prepare the necessary tenant information in line with the statutory requirements.
Analyzing charging cards & contracts
Do you have the optimal tariff combination for your driving profile? Are your charging card(s) working against each other, or are you paying unnecessary roaming surcharges? We compare the current contracts with the tariffs from our LadeGuide database.
Strategy & lifetime analysis
How do you implement LadeGuide strategies (the 80-percent rule, tapering) consistently? Which charging times are cost-optimal — and how can the daily routes be tuned for efficiency? We create an individual strategy recommendation.
Consulting offer for fleet operators
- You share the most important data: fleet size, vehicle types, the current charging infrastructure, and your main contracts.
- We analyze the numbers and prepare an audit report with concrete savings potentials and actions.
- Together we discuss the optimization: switch tariffs, adapt the infrastructure, or add training.
A customer gift: the LadeGuide voucher
Give your customers support when they drive your EV for the first time. A voucher for personal charging support keeps the promise you make: charging, setting up the app, and charging cards become part of the buying experience, instead of the first hurdle after delivery.
Example voucher text
“Your customer gets a personal LadeGuide appointment — on site or remote —, in which they charge on their own for the first time, use their charging card, and understand their tariff. Validity: 12 months from purchase.”
Voucher request →Why it pays off for you
LadeGuide support raises the perceived value of the purchase, reduces complaints over the “first charge”, and keeps you in the customer's memory, when they are near you again in 12 months — not at your competitor's.
Discuss the concept →For private customers — this way →
The practical part as personal charging support for private EV buyers: at the wallbox, at the charging station, or remote.
To the private offer →Your individual offer — request it
Whether a training in the fleet, the sales, or a customer gift: you briefly describe what runs at your company, and we send you your concrete offer — with scope, date options, and transparent workload.
