Problems solved by technology
[0002] Existing electric vehicles usually require the battery temperature to be controlled within a small range, such as 10 to 50 degrees. This range is very narrow and is very close to the ambient temperature. It is difficult to exchange heat with the air using only cooling water. accomplish
Generally, electric vehicles use a compressor to drive the coolant to additionally cool the water circuit to achieve temperature control, but for racing cars, the compressor and coolant bring about an increase in system complexity and a decrease in system reliability

The invention discloses a battery cooling device of an electric racing bicycle. The battery cooling device comprises an ice water tank, a battery pack heat dissipation device and a motor heat dissipation device, wherein the ice water tank is communicated with an electronic thermostat through a water pipe and is connected with the battery pack heat dissipation device through the electronic thermostat; the battery pack heat dissipation device is communicated with the ice water tank through a three-way pipe; the three-way pipe is connected with a DCDC water inlet / outlet; the DCDC water inlet / outlet is connected with an electronic water pump and is communicated with the electronic thermostat through the electronic water pump. According to the battery cooling device disclosed by the invention,a working water path can be effectively controlled through the electronic thermostat arranged on the battery cooling device and the complexity of a cooling system is reduced; a condition that extra pipeline, compressor and the like are needed, caused by the fact that cooling water and a second medium are subjected to heat exchange, is avoided; meanwhile, one cooling medium is adopted and ice waterand other cooling water can be mixed, so that the system does not need to be separated, unnecessary sealing requirements are reduced and the reliability of a vehicle system is improved.
Description
technical field [0001] The invention relates to the technical field of battery cooling, in particular to a battery cooling device for an electric racing car. Background technique [0002] Existing electric vehicles usually require the battery temperature to be controlled within a small range, such as 10 to 50 degrees. This range is very narrow and is very close to the ambient temperature. It is difficult to exchange heat with the air using only cooling water. accomplish. Generally, electric vehicles use a compressor to drive the coolant to additionally cool the water circuit to achieve temperature control, but for racing cars, the compressor and coolant bring about an increase in system complexity and a decrease in system reliability. How to efficiently cool batteries for racing applications without using additional compressors and coolants has become an urgent problem to be solved. [0003] According to the problems existing in the temperature control of electric vehicles...
