Abstract

The present invention discloses a PTC heater for a novel electric car, and an integrated control system. The PTC heater comprises a heater body and a radiator. The heater body is disposed inside a shell of the heater. The shell of the heater is provided with at least one a temperature sensor and a ground line, wherein N is a natural number greater than 2. According to the radiator, the heater body is provided with a fluid vessel, wherein the fluid vessel is provided with a fluid inlet and a fluid outlet; or the radiator is array heat sinks disposed on the heater body. The control system comprises a controller, a temperature collection module, an insulation detection module, a switch drive module, a voltage collection module, a current collection module, and a control and power supply wiring terminal. The controller is connected with the temperature collection module. The temperature collection module is connected with a temperature detection wiring terminal. The switch drive module is connected with a switch device. The switch device is connected with the heater body. The PTC heater has the advantages of providing a hot air source, sharing a piece or a device with a battery heat dissipation system, being efficient and saving energy. The whole system is stable, is highly integrated, is convenient to use, and is easy to maintain.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a novel PTC heater and integrated control system for electric vehicles. Background technique [0002] At present, in the field of new energy vehicle technology, electric vehicles generally use a power battery pack (usually a lithium battery pack) as a power source; the power battery needs to be heated at low temperature to ensure that the battery can be used normally; To generate a heat source, the electric vehicle itself does not have a power device to generate a heat source, so it cannot provide a heat source to the power battery pack; at the same time, it cannot provide a warm air heat source required for air conditioning, defrosting, etc. [0003] At present, the heaters used in power battery heating systems in the industry are mainly PTC heaters or resistive heating films; the two heaters are simple in structure and function, and are only used as a single heater. device, ...
