The invention discloses a PTC controller for achieving online software updating through a PWM port. The PTC controller comprises a PTC controller body, a voltage collection part, a temperature collection port and the PWM communication port are formed in the PTC controller body, and a main control board is arranged in the PTC controller body; a processor module, a voltage collection module, a temperature collection module, a current collection module, a driving control module and a PWM communication module are arranged on the main control board, the processor module is connected with the voltage collection module, the temperature collection module and the current collection module separately, and the voltage collection module is connected with an external high-voltage input power source. The PTC controller is simple in structural principle and high in intellectualization degree, on the premise of not changing the system design of a whole vehicle, with the help of the PWM signal input port, online software upgrading is achieved by additionally arranging a communication circuit in the PTC controller, and the PWM collection function of the controller is not influenced. Accordingly, thefunctions which can be achieved merely by adopting communication ports such as CAN communication ports are achieved.
Description
technical field [0001] The invention relates to the technical field of PTC controllers, in particular to a PTC controller which realizes online updating of software through a PWM port. Background technique [0002] At present, in order to reduce the cost of new energy vehicles, PWM signals are mostly used to directly control the output power of the PTC controller. In the later period, due to function updates or design changes, the software of all PTC controllers in the vehicle needs to be upgraded. At this time, only the controller can be replaced or the controller can be disassembled to update the software through BDM. The disassembly process takes 7 to 8 hours, and because the controller has no communication function, it is impossible to effectively distinguish which cars have updated software. The cost of the entire upgrade project was as high as more than 800 yuan. Contents of the invention [0003] The object of the present invention is to provide a PTC controller w...
