[0025] Reference figure 1 with figure 2 As shown, the present invention provides an electric vehicle power battery temperature controller 1, which is arranged near the battery 2. The temperature controller 1 includes a number of temperature probes 10, a microprocessor 12, a heating device 13, and electrical connections therewith The temperature probe 10 and the heating device 13 are electrically connected to the microprocessor 12 and the battery 2, respectively. When the current battery temperature measured by any of the temperature probes 10 is less than the set lower limit temperature, the microprocessor 12 Send a heating control command to start the heating device 13 to heat the battery 2. When the current battery temperature measured by any temperature probe 10 is greater than the set upper limit temperature, the microprocessor 12 sends a heating control command to stop the heating device 13 Heating of battery 2. In the present invention, the battery temperature controller...
