The invention discloses a safety protection control system for an electric heater of an electric vehicle, and relates to the technical field of electric vehicle safety control. The invention includes a first temperature acquisition unit, a second temperature acquisition unit, an MCU, a voltage acquisition unit, a voltage control execution module, an electric heater control drive unit, a current sampling unit, a temperature switch execution module, an MCU anti-crash protection unit, an overcurrent flow comparison unit, signal integrated processing unit, and protection signal output unit; the first temperature acquisition unit is used to collect the operating temperature information of the electric heater, and transmit the operating temperature information to the MCU; the second temperature acquisition unit is used It is used to collect the circuit board temperature information of the electric heater drive control circuit board; the present invention can effectively ensure the reliable operation of the electric heater, timely and effectively shut down the electric heater control drive unit and cut off the power supply of the electric heater when a fault occurs, and timely and effectively protect The life safety of drivers and passengers and the safety of vehicles.
Description
technical field [0001] The invention belongs to the technical field of safety control of electric vehicles, and in particular relates to a safety protection control system for electric heaters of electric vehicles. Background technique [0002] In winter, the battery life of new energy electric vehicles will generally be greatly reduced, mainly because the electrolyte viscosity of the battery pack increases at low temperatures and the charge and discharge performance of the battery pack decreases. New energy electric vehicles can solve the problem of preheating the battery pack of new energy vehicles at normal operating temperature by installing a car parking heater, so as to solve the problem of the decline in battery life of new energy electric vehicles in low temperature environments in winter, and avoid low temperature charging on the battery pack. damage. [0003] However, the heating and heating system of new energy electric vehicles has the failure of the control cir...
