8KW Low-Temperature Resistant Off-Board Charger

The 8KW Low-Temperature Resistant Off-Board Charger is a high-power independent charging device specially designed for low-temperature environments. Its core function is to convert three-phase AC power into stable DC power, efficiently charging the power batteries of industrial equipment such as electric forklifts and stackers.

Serving as an “energy supply station” in low-temperature environments, it operates stably under extreme cold conditions. It adjusts charging parameters through intelligent algorithms, balancing fast charging efficiency and battery protection, making it an essential supporting device for logistics, warehousing, and outdoor operations in cold regions.

Core Advantages

This 8KW Low-Temperature Resistant Off-Board Charger adopts low-temperature-adapted chips and an efficient thermal insulation & heat dissipation structure. It can operate stably in a wide temperature range of -40℃ to 50℃ in scenarios like outdoor warehouses in northern winters and cold-region ports, with a 100% startup success rate.

Compared with ordinary chargers, its low-temperature charging efficiency is improved by 25%, avoiding operation interruptions caused by low-temperature power loss.

To meet the high-frequency outdoor operation needs of electric forklifts and cleaning equipment, it is equipped with an IP41 dustproof & waterproof shell to resist rain, snow, and dust. The lightweight aluminum alloy body weighs only 55KG, 18% lighter than competitors, making it easy to move and deploy.

It supports intelligent BMS communication and multiple protection functions, matching battery status in real time, preventing overcharging and overheating, and extending battery life by 30%, combining excellent low-temperature adaptability and operational reliability.

Specifications

Applications

1. Electric Forklift / Stacker

Customized models developed for a Russian cold-chain logistics company. Over 800 units exported to Siberian warehouses, working stably for more than 12 hours per day at -35℃, with written praise from the customer: “Excellent low-temperature performance”.

2. Electric Handling Vehicle

Cooperated with automakers in Northeast China, supplying 2,000 units to automotive parts factories in cold regions, suitable for cross-scenario operations in workshops and outdoors.

3. Cleaning Equipment

Served 15 municipal authorities in northern China, suitable for outdoor low-temperature sweepers and snow removal vehicles. Dustproof, waterproof, and low-temperature resistant design adapts to complex cold-region working conditions.

Certification & Quality

Products are certified with CE, ISO9001, GB/T 34131-2015, and have passed special low-temperature performance tests.

The factory is equipped with fully automatic production lines and precision low-temperature test chambers. Each unit undergoes 36 quality control procedures, including 100-hour full-load aging test at -40℃, insulation voltage resistance, and sealing tests.

Certification documents, production line photos, and low-temperature quality control inspection records are available. Defect rate is controlled within 0.2%, meeting global cold-region procurement standards.
