Problems solved by technology
[0002] At present, electric vehicle controllers mainly include power interface, control circuit board and motor signal interface. Among them, electric tricycles and electric vehicles need to use relatively high-power electronic components for the control circuit board due to their high power, so that the control circuit board generates heat when it is working. The controller is relatively large and requires high heat dissipation for the controller. At present, the usual practice is to increase the volume of the controller and install a cooling fan inside to improve the heat dissipation effect; the controller is generally installed at the bottom of the vehicle, and the vehicle will be bumped during driving. If the controller is installed inside the vehicle, it will be inconvenient for maintenance, and if the volume is too large, there will be no installation space inside the vehicle. For various reasons, the output power of the existing controller is limited, or the controller’s low reliability

The invention relates to an oil cooling electric vehicle controller. The oil cooling electric vehicle controller is characterized in that seal structures are arranged among housings and among housings and all interfaces, a power wiring terminal not only achieves the function of connecting a control circuit board with a power source and a motor, but also simultaneously achieves the function of fixing the control circuit board, the housings are filled with cooling oil, an oil cooling mode is used for heat dissipation, and therefore heat dissipation efficiency of the oil cooling electric vehicle controller is greatly improved. The oil cooling electric vehicle controller has the advantages of being reasonable in setting, compact in structure, convenient to connect and use, and safe and reliable.
Description
technical field [0001] The invention relates to an electric vehicle controller technology, in particular to an oil-cooled electric vehicle controller with good sealing, waterproof and heat dissipation effects.
