48V Bi-directional IP67 High-Efficiency EV DC/DC Converter

The 48V Bi-directional IP67 High-Efficiency EV DC/DC Converter is a core electronic control component designed for 48V system electric vehicles and small electric operation equipment. Its core function is to realize bi-directional power conversion: it can not only efficiently convert the high-voltage DC power of electric vehicle power batteries into 48V stable low-voltage DC power to supply power to on-board instruments, central controls, auxiliary motors and other electrical equipment, but also reversely transmit the energy recovered from braking to the power battery for storage, realizing energy recovery and energy saving. 

As a "bi-directional energy-saving full-protection power conversion center", it focuses on IP67 full dustproof & waterproof and 48V bi-directional conversion, adapts to dusty and watery harsh scenarios such as electric vehicle outdoor driving and construction site operations, ensures stable power supply and energy recovery through intelligent voltage stabilization algorithms, balances high efficiency and reliability, and is also compatible with electric forklifts, stackers and other equipment, an indispensable core supporting component for multi-scenario new energy electric equipment.

Core Advantage

This 48V Bi-directional IP67 High-Efficiency EV DC/DC Converter adopts bidirectional resonant conversion technology and IP67 fully sealed protection process. In scenarios such as outdoor long-distance driving of electric vehicles, heavy-load operation of construction site electric forklifts, and maintenance of outdoor cleaning equipment, it can achieve complete dust and water protection, with no damage after being submerged underwater at 1 meter for 30 minutes. It effectively resists the erosion of rain, dust, and sand, has excellent protection performance, and reduces the equipment failure rate by 80%. The 48V bidirectional power conversion is combined with an ultra-high conversion efficiency of over 97%, which is 22% more energy-efficient than similar products. The braking energy recovery can increase the range of electric vehicles by about 15%. At the same time, it can efficiently meet the power supply requirements of industrial equipment. 

The body is made of lightweight and high-strength aluminum alloy material, weighing only 7.2KG, which is 13% lighter than similar products of the same specification. The volume is compact, making it easy to install and deploy in the engine compartment of electric vehicles or in the narrow spaces of small equipment, without increasing the equipment's load. It is equipped with intelligent bidirectional adaptation and multiple protection technologies, which can quickly respond to the bidirectional needs of vehicle power supply and energy recovery. It also has overvoltage, overcurrent, overtemperature, reverse connection, and short-circuit protection, avoiding electrical control failures caused by harsh environments. It combines IP67 full protection, 48V bidirectional conversion, high efficiency, and stability, perfectly adapting to the long-term and high-frequency usage requirements of 48V system electric vehicles, electric forklifts, stackers, cleaning equipment, and other electric equipment.
