Arctic weather affects charging efficiency for pure electric buses

Under extremely cold conditions, charging facilities may be affected by freezing and icing, which decreases charging speed or even induces fault. Charging efficiency will also be affected as a result of prolonged charging time and energy consumption. The reliability and efficiency of charging facilities are also faced with challenges.

Arctic weather affects reliability for pure electric buses

Extremely cold weather imposes extra challenges on mechanical components, which are prone to damages, performance and durability drop.

How does Yutong pure electric bus meet the challenges of arctic weather?

How does Yutong keep the battery at a suitable working temperature?

Yutong adopts an integrated battery thermal management system. It meets the fast heating demand at -40°C by using a high-efficiency battery liquid heater and matching suitable heating power. Besides, to ensure battery work within an appropriate temperature range, Yutong improves the thermal conductivity of the heat-conductive adhesive in the battery pack, reduces the thermal resistance between the cell and the cooling plate, and sprays thermal insulation materials at the bottom of the pack.

How does Yutong pure electric bus ensure the passenger comfort?

Yutong has made an effort in vehicle heating. Yutong buses are equipped with a low-temperature heat pump air conditioner and an efficient auxiliary heating system. It quickly warms up the vehicle, largely reduces energy consumption, and therefore prolongs battery lifespan. The design, an ideal solution for balancing all aspects, combines passenger comfort with energy efficiency.

How does Yutong pure electric bus guarantee reliability and stability?

Yutong adopts enhanced anti-corrosion technology in the core components such as bearing structure, chassis frame, and the bottom area prone to corrosion. The technology prevents structural corrosion for vehicle whole life cycle. The comprehensive chassis armor protects key components from tear and wear under severe road conditions, meeting the operation requirements and protecting the passenger safety in arctic regions.
