What does PDU mean in new energy vehicles?
1 Answers
Electric vehicle PDU refers to the high-voltage power distribution box of electric vehicles. Its function is to electrically connect high-voltage components through busbars and wiring harnesses, providing charging and discharging control, power-on control for high-voltage components, circuit overload and short-circuit protection, high-voltage sampling, low-voltage control, etc., for the high-voltage system of new energy vehicles, protecting and monitoring the operation of the high-voltage system. Below is extended information about PDU: 1. Module functions: PDU can also integrate functions such as the BMS main control, charging module, DC module, PTC control module, etc. Compared with traditional PDUs, it includes more vehicle function modules, is more integrated in functionality, more complex in structure, and has cooling structures such as water cooling or air cooling. PDU is flexibly configurable and can be customized according to customer requirements, meeting the needs of different customers for various vehicle models. 2. Advantages: The entire distribution box adopts sheet metal or aluminum alloy housing with excellent heat dissipation and vibration resistance, with high safety and waterproof sealing levels. It also has significant advantages in lifespan, power consumption, size, and weight.
