Leaving your electric scooter charging overnight is a common question among users. The direct answer: yes, in most cases it is safe, as long as you use the original charger and the battery is lithium-based with overcharge protection. Modern models automatically stop charging when they hit 100%, preventing damage.
However, there are important precautions. Lithium batteries can degrade faster if exposed to extreme temperatures or if the charger is low quality. It is recommended to charge in a dry place, away from flammable materials, and to verify that the scooter has a Battery Management System (BMS).
In Maringá, Municipal Law No. 11.981/2025 and CONTRAN Resolution 996/2023 establish rules for scooter use. Knowing these regulations helps avoid fines and ensures safety. Let's break down each point below.
What Maringá's 2026 Regulations Say
In Maringá, Municipal Law No. 11.981/2025 defines limits: a maximum speed of 20 km/h on bike lanes and cycle paths, and 6 km/h on sidewalks, squares, and parks. Wearing a helmet is mandatory.
It is also forbidden to ride on expressways or roads with a speed limit above 40 km/h. The scooter must have a speed indicator, a bell, and nighttime lighting. These rules apply to electric scooters and other micro-mobility devices.
Federal Rules: CONTRAN 996/2023
CONTRAN Resolution 996/2023 classifies electric scooters as motorized individual mobility devices. The maximum speed is 60 km/h (equipment technical limit).
No driver's license (CNH) is required for scooters up to 32 km/h. For mopeds above 50 cc, a category A license is obligatory. The minimum age to ride without an accompanying adult is 16.
Market Data: Range, Cost, and Charging
On average, an electric scooter covers 20 to 40 km per charge, depending on model and rider weight. The cost to recharge the battery is low: between R$ 0.10 and R$ 0.30 (approx. USD 0.02 to 0.06) per full cycle, considering Maringá's electricity tariff of approximately R$ 0.85/kWh (about USD 0.17/kWh).
Charging time varies from 3 to 6 hours, depending on battery capacity (standard 36V/10Ah to 48V/13Ah). Models with larger batteries take longer but offer better range.
Scooter Prices in the Market
Prices vary by category. Entry-level scooters cost between R$ 1,800 and R$ 3,500 (approx. USD 360 to 700). Premium models, with longer range and suspension, fall in the range of R$ 4,000 to R$ 8,000 (approx. USD 800 to 1,500).
When buying, consider your use case (daily commute, leisure) and the available charging infrastructure. Opt for brands that offer technical support and warranty, like the ones we sell at Patinep Store.
How to Charge Safely Overnight
Use only the original charger, or one with safe charging certification. Turn off the scooter before plugging in. Avoid charging on surfaces that retain heat, like carpets or sofas.
If your battery lacks overcharge protection (older models), it is better not to leave it charging all night. In that case, charge under supervision and unplug once fully charged.
Extra Battery Care Tips
Keep the battery between 20% and 80% charge to extend its lifespan. Avoid frequent full discharges. If you will not use the scooter for days, store it with about a 50% charge.
Periodically clean the metal contacts with a dry cloth. Protect the scooter from rain and excessive moisture. If you drop the scooter or it suffers an impact, inspect the battery and charger.
