Electric vehicle battery box with overheat protection function

The utility model discloses an electric vehicle battery box with an overheat protection function. The electric vehicle battery box comprises a low-temperature temperature control switch (001), a high-temperature temperature control switch (002), a battery (003), a diode (004) and the like. The low-temperature temperature control switch (001) and the diode (004) are connected in parallel to form a low-temperature temperature control module and then are connected in series with the high-temperature temperature control switch (002) and the battery (003); the low-temperature temperature control module is used for protecting the battery (003) from suffering from overheat damage in the charging process; the high-temperature temperature control switch (002) is used for preventing the condition that due to a short circuit, a wire or the battery (003) is instantaneously overheated to cause a fault of an electric vehicle and even a fire accident.
