Rwanda’s hilly terrain reduces electric vehicle (EV) range by up to 20%, but smart driving techniques, route planning, and terrain-suited EV models can help. Steep climbs demand more energy, while regenerative braking on downhill stretches recovers some power. With charging costs 50% lower than diesel and growing infrastructure, EVs are increasingly practical in Rwanda. Here’s how to navigate the challenges:
- Efficient Driving: Smooth acceleration and steady speeds save energy.
- Route Planning: Choose gentler slopes, pre-map charging stops, and drive during cooler hours.
- Terrain-Specific EVs: Models like the Radar RD6 (410 km range) and OX Truck (170 km range) perform well on rugged roads.
- Charging Network: Affordable rates (Rwf 94/kWh) and stations at strategic points make long trips viable.
With the right strategies and vehicles, EVs are proving reliable even in Rwanda’s demanding landscape.

3. Effects of Hills on EVs
Rwanda’s hilly landscape creates unique challenges for electric vehicles (EVs), influencing their range, power demands, and battery health over time.
3.1 Battery Range and Hills
Navigating steep hills in Rwanda requires extra energy, which can cut an EV’s range by as much as 20%. However, regenerative braking on downhill stretches helps recover some of this energy. While it doesn’t completely balance out the energy used during climbs, it does improve overall range efficiency by reducing the net energy loss.
3.2 Power Output and Battery Health
Climbing steep inclines puts additional strain on an EV’s battery, requiring more energy output. To handle this, effective battery management becomes crucial. This includes managing temperature, optimizing power usage, and taking advantage of energy recovery systems during descents.
Frequent deep discharges caused by climbing can speed up battery wear if not carefully monitored. Regular battery maintenance and proper operation are key for EVs to perform well and maintain longevity in Rwanda’s demanding terrain.
3.3 EV Case Studies in Rwanda
Real-world tests have shed light on how EVs perform on Rwanda’s roads. The Radar RD6 electric pickup, with a range of 410 km, has shown strong performance across varying elevations [1]. It also proved to be cost-effective, with charging expenses significantly lower than diesel fuel costs for long-distance trips.
The Radar RD6’s success highlights that, with the right vehicle and careful operation, EVs can be a reliable transportation choice even in hilly areas. These findings emphasize the need for strategies that optimize EV performance in Rwanda’s unique environment.

4. Improving EV Performance in Hilly Areas
Driving smart, planning ahead, and picking the right vehicle are key to getting the most out of electric vehicles (EVs) in Rwanda’s rugged landscape.
4.1 Efficient Driving Techniques
Driving smoothly can cut energy use by as much as 15% compared to aggressive acceleration and braking [1]. For example, gradual acceleration and maintaining a steady pace during uphill climbs can make a big difference in efficiency. This was evident during the Radar RD6’s East African journey, where smart driving techniques proved effective [1].
But driving habits aren’t the only factor. Careful planning can also boost an EV’s range in hilly regions.
4.2 Route Planning for Better Range
Planning your route can make a huge difference in how far your EV can go. A 2,400-kilometer trip from Kigali to Nairobi highlighted the importance of this approach [1]. Key tips include:
- Choosing routes with gradual elevation changes
- Pre-mapping charging stops before steep climbs
- Driving during cooler parts of the day
- Considering alternative routes with gentler slopes when possible
These simple strategies can help maximize your EV’s range in challenging terrains.
4.3 Choosing Suitable EV Models
For Rwanda’s steep and demanding roads, picking the right EV is crucial. The OX Truck, tailored for Rwanda, delivers a range of 170 km [4], while the EKON bike by Spiro offers up to 100 km in urban areas like Kigali [2].
To tackle hilly terrain effectively, look for EVs with high-capacity batteries, strong regenerative braking, powerful motors, and GB/T charging compatibility. Models like the Radar RD6, boasting a 410 km range, show how modern EVs are well-suited to Rwanda’s tough topography [1].
5. EV Infrastructure and Support in Rwanda
Rwanda is making strides in electric mobility with a growing network of charging stations and policies designed to tackle the challenges of its hilly landscape.
5.1 Expanding Charging Network
Rwanda’s charging infrastructure is being developed with careful planning to meet the needs of EV users navigating its rugged terrain. Companies like Kabisa are setting up charging stations at strategic points, such as hilltops and valleys, to help with energy recovery during drives. At just Rwf 94/kWh, charging an EV like the Radar RD6 is far more affordable than fueling diesel vehicles, with a full charge costing roughly Rwf 6,016 [1] [3].
5.2 Role of Local Platforms
Local platforms are essential in supporting EV adoption and addressing terrain-specific challenges. AutoMag.RW acts as a key resource, offering real-time updates on charging locations and tips for maintaining EVs in hilly areas. Partnering with dealers like AUTO24.rw, they also help connect buyers to EV models tailored for Rwanda’s landscape.
These efforts align with Rwanda’s broader push toward electric mobility. For instance, Spiro’s EKON electric bike, priced at $500, is playing a part in Kigali’s shift to an all-electric public transport system, blending affordability with eco-friendly benefits [2].
The success of Rwanda’s charging network was showcased during East Africa’s first EV road trip in September 2024. This event highlighted how well-placed infrastructure and strong local partnerships can make long-distance EV travel possible, even in tough terrains [1].
6. Conclusion: Tackling Terrain Challenges for EVs
Rwanda’s hilly landscape poses challenges for electric vehicle (EV) range and performance, but steps are being taken to make electric mobility a practical option. For instance, OX Delivers has introduced electric trucks specifically designed for Rwanda’s rugged roads, highlighting the potential of terrain-focused EV designs.
Several strategies can help improve EV performance in Rwanda’s demanding terrain:
| Strategy | Benefit | How It Works |
|---|---|---|
| Smart Route Planning | Conserves battery life | Use navigation tools to identify energy-efficient routes |
| Infrastructure Expansion | Enables longer trips | Install charging stations at strategic high-altitude locations |
| Terrain-Compatible Vehicles | Improves reliability | Choose EVs designed to handle steep and uneven roads |
The success of electric mobility in Rwanda depends on a joint effort from the government, private companies, and the public. With operating costs up to 60% lower than diesel vehicles and a growing charging network offering affordable rates of Rwf 94/kWh [1], EVs are becoming an increasingly practical solution. As charging infrastructure expands and more terrain-suited EV models become available, Rwanda’s hills are becoming less of an obstacle to the adoption of electric transportation.
