# Battery swapping explained: why swap beats plug-in for African fleets

> Working motorcycles cannot wait hours to charge. Swap cabinets turn a 4–6 hour charge into a 45-second stop and move the battery problem from the rider to the operator.

## The problem with plugging in

A commercial electric motorcycle with a 2–3 kWh pack has a real-world range of 60–90 km. A boda rider covers 100–200 km a day. Charging at home overnight does not cover the day, daytime charging means lost income, and most riders rent rooms without a reliable socket or a safe place for a battery. For private cars in Europe plug-in charging works; for a working two-wheeler in Nairobi or Dar es Salaam it does not.

## How a swap network works

1. The rider pulls up to a **swap cabinet** — a steel locker with 8–16 bays, each bay charging one battery.
2. They authenticate (RFID, app or phone number), open a bay, insert the depleted pack and take a full one. Under **45 seconds**.
3. Mobile money charges the swap (typically 30–60 KES per pack in Kenya) or the daily subscription.
4. The cabinet charges the returned pack at a controlled rate, monitors temperature and balances cells; data flows to the operator's platform.

MargTor's reference cabinet has **12 bays and a 16 kW** grid/solar connection and can cycle roughly 24 packs a day — enough for 12–20 riders at two swaps each.

## Why swapping suits Africa specifically

- **Grid quality.** Many areas have unreliable or no grid. A cabinet with a solar array and an ESS buffer charges slowly all day and dispenses energy instantly — it decouples charging speed from the rider's time.
- **Battery cost and safety.** The battery is 30–40% of the vehicle price. If the operator owns it, the vehicle becomes affordable and the battery is charged under supervision instead of in a bedroom.
- **Standardisation.** One pack format across 2W and 3W platforms lets the same cabinet serve boda motorcycles, cargo trikes and even boats or homes.
- **Density beats size.** A cabinet every 10–15 km inside a 30 km operating radius removes range anxiety more cheaply than doubling battery size.

## Economics of a cabinet

A cabinet earns on energy margin: solar electricity costs a fraction of the swap price, and grid electricity in Kenya (~20–25 KES/kWh) still leaves a healthy spread on a 30–60 KES swap. In the MargTor model a swap network **returns its investment in 8–10 months**, and a network becomes self-sustaining at roughly **300 active bikes**. Each hub also creates around 20 local jobs — attendants, technicians, security, shopkeepers who host cabinets.

## What can go wrong

- Non-standard packs from mixed vehicle suppliers.
- Under-sized solar or ESS leading to empty cabinets at evening peak.
- No telematics — operators cannot see where demand is or which packs are degrading.
- Siting cabinets by convenience instead of rider flow (stages, markets, fuel stations).

A technical partner's job is to design the pack, the cabinet, the energy supply and the data layer as one system — which is why MargTor engineers them together.
