YIHU electric tricycles are engineered for heavy load transportation, powerful climbing, and all-scenario adaptation in urban and rural areas. The core of daily maintenance is to hold the four bottom lines of battery life, power output, braking safety and body durability. Combined with the load and climbing characteristics of YIHU models, this guide provides a differentiated and actionable maintenance plan, abandoning one-size-fits-all general maintenance tips and precisely adapting to the usage scenarios of YIHU tricycles.
I. Battery Maintenance: The Power Foundation for YIHU’s Heavy Load & Climbing
(Core Keywords: YIHU Special Charger, Heavy Load Range, Low-Temperature Climbing, Anti-Low Voltage)
YIHU electric tricycles often operate under full load and continuous steep slope driving conditions. The battery is the core of power, and its maintenance directly determines climbing power and load range.
- Charging: Only use YIHU original/matched chargers, never mix
- Must use YIHU standard chargers with parameters strictly matching the vehicle’s battery (e.g., 48V/60V lead-acid/lithium battery). Mixed chargers may cause overcharging, bulging, undercharging and range reduction. Especially after heavy load driving, mismatched chargers will aggravate battery loss.
- Charging timing: Charge immediately when the remaining power is 30%-40% after load/crossing slopes to avoid storage with low voltage; for daily short-distance load transportation, charge as you use to keep the power in the 50%-80% range and reduce the impact of high-current discharge on the battery.
- Seasonal charging tips: In summer, cut off the power immediately after the charger turns green to prevent high-temperature overcharging; in winter (low temperature affects climbing power), float charge for 3-4 hours after the green light to activate battery activity and ensure climbing torque output; choose a ventilated and dry place for charging, away from direct sunlight and water accumulation, and prohibit charging in the carriage.
- Charging sequence: Plug in the battery end first, then the power end; unplug the power first after full charge, then disconnect the battery connection to avoid battery and electric control damage from current impact.
- Usage: Adapt to YIHU’s heavy load & climbing, reduce battery load
- When starting with heavy load or driving on steep slopes, twist the throttle gently and accelerate slowly, cooperate with pedal assist to avoid instantaneous high-current discharge and protect the battery and motor; prohibit overloading (the rated load of YIHU models is 300kg, overloading will keep the battery under high load for a long time and shorten its service life).
- After driving in rainy/muddy roads with load, wipe the battery surface and terminals in time to prevent short circuit; for long-term storage (e.g., off-season), charge once a month to maintain battery activity and avoid scrapping due to low voltage.
- Regular inspection: Clean battery terminals monthly to remove oxide layer; if there is a sudden drop in range or overheating during charging, send it to YIHU after-sales service for testing immediately to troubleshoot battery faults.
II. Power System Maintenance: The Core Guarantee for YIHU’s Climbing & Heavy Load
(Core Keywords: YIHU Brushless Motor, 12-Tube Controller, Climbing Torque, Heavy Load Power)
YIHU is equipped with a high-power brushless motor + 12-tube anti-rollback controller, specially designed for heavy load and climbing. The maintenance focus is to ensure stable power output and avoid weak climbing and stuck during heavy load.
- Motor Maintenance: Guard the core climbing power
- Daily inspection: Check the motor appearance weekly for bumps, water ingress and abnormal noise; after climbing with heavy load, check the motor temperature, and stop using it if it overheats abnormally until it cools down.
- Cleaning and protection: Do not rinse the motor with a high-pressure water gun, wipe the surface dust with a damp cloth; after driving on muddy roads, clean the soil around the motor to prevent blocking the heat dissipation port and affecting heat dissipation efficiency during climbing.
- Regular overhaul: Check the motor fixing screws every 3 months to ensure tightness; if there is weak climbing or increased noise, troubleshoot the motor bearings and coils in time, and replace YIHU original parts if necessary.
- Controller Maintenance: Stabilize climbing torque output
- Protection: The controller is the “brain” of YIHU’s power, installed in a concealed part of the body to avoid direct sunlight and rain; after driving in rainy days with load, wipe the controller surface and wiring ports in time to prevent short circuit.
- Operation: Avoid frequent violent throttle twisting and sudden braking when carrying heavy loads/climbing to reduce current impact on the controller; if there is stuck climbing or power interruption, check the controller wiring and retighten loose parts.
- Overhaul: Send to YIHU after-sales service to test controller parameters every 6 months to ensure stable climbing torque output and adapt to heavy load conditions.
III. Braking & Chassis Maintenance: The Safety Bottom Line for YIHU’s Heavy Load & Climbing
(Core Keywords: Heavy Load Braking, Steep Slope Braking, Chassis Fastening, Load Stability)
YIHU often runs at full load and goes up and down steep slopes. Braking and chassis are directly related to safety. The maintenance focus is on sensitive braking, stable chassis and load-adapted tires.
- Braking System: No brake failure during heavy load/steep slope driving
- Daily inspection: Check the front and rear brakes (drum/disc brakes) weekly, replace YIHU original parts immediately when the brake pad wear exceeds 1/3; adjust the brake cable tightness to ensure moderate brake stroke and stable braking when going down steep slopes with heavy load.
- Cleaning and maintenance: After driving in rainy/muddy roads, wipe the brake drum/disc to remove soil and avoid brake failure; add lubricating oil to the brake rotating shaft and brake lever monthly to reduce jamming.
- Special scenarios: When going down steep slopes with heavy load, gently step on the brake to decelerate in advance to avoid sideslip caused by sudden braking; if there is abnormal brake noise or reduced braking force, overhaul immediately and prohibit climbing with faults.
- Chassis/Frame: No loosening under heavy load, no bumping during climbing
- Fastening inspection: YIHU frame is specially designed for heavy load. Check the connecting screws of frame, carriage and rear axle weekly, and focus on fastening after heavy load bumping to prevent body deformation caused by loosening.
- Rear axle/gear oil: Replace YIHU special gear oil every 6 months to ensure good lubrication of the rear axle differential, reduce wear during heavy load climbing and ensure stable power transmission.
- Tire maintenance: Use YIHU original tubeless tires (3.00*8 specification), check tire pressure monthly, keep the pressure slightly higher under heavy load (5%-10% higher than the standard) to enhance load-bearing and grip; clean tire surface debris to avoid puncture and affect climbing stability.
IV. Body & Electrical Maintenance: The Key to YIHU’s Durability in All Scenarios
(Core Keywords: Load Anti-Rust, Climbing Waterproof, Urban & Rural Scenario Adaptation)
YIHU covers street vending, delivery, farm, rural mountain roads and other scenarios. Body and electrical maintenance need to adapt to complex environments and extend service life.
- Body Maintenance: Rust-proof under heavy load, durable in complex scenarios
- Cleaning: Clean up debris and soil in the carriage after each load transportation, wipe the body with a neutral cleaner to avoid paint corrosion; a waterproof film can be pasted inside the carriage to reduce corrosion from fresh food, building materials and other goods.
- Anti-rust: Apply anti-rust paint to the welding parts of the frame and carriage every quarter, especially in humid scenarios such as rural muddy roads and coastal areas, to prevent rust and cracking; repair the paint surface in time after heavy load bumps to avoid expanding rust.
- Carriage inspection: Regularly check the carriage bottom plate and side panels for deformation after heavy load, and reinforce loose parts in time to ensure load safety.
- Electrical Wiring: No short circuit during climbing/wading, stable in complex scenarios
- Inspection: Check the whole vehicle wiring monthly for aging, damage and loosening, and wrap damaged parts with insulating tape; focus on checking the headlight and turn signal wiring to ensure normal lighting during night load transportation and climbing in urban and rural areas.
- Waterproof: Avoid wading too deep when driving in rainy days (exceeding the motor base) to prevent short circuit; after wading, wipe the wiring interfaces in time and turn on the lights to dry moisture.
- Spare parts: When replacing electrical parts, choose YIHU original parts to ensure matching the vehicle’s power and load requirements and avoid compatibility faults.
