Abstract

The invention belongs to the field of instrument test, and further relates to a tester for testing battery packs. The tester comprises a temperature control device and a cold and heat supply source, wherein the temperature control device is connected with a to-be-tested battery pack; the cold and heat supply source is connected with the temperature control device; and a cold and heat switching device is arranged between the temperature control device and the cold and heat supply source to supply cold to the temperature control device when the temperature of the to-be-tested battery pack is greater than a threshold and supply heat to the temperature control device when the temperature of the to-be-tested battery pack is smaller than the threshold. The tester is capable of effectively solving the technical problems that the outer thermal control temperature consumption is high, the temperature control precision is low and durability test cannot be carried out.

Description

technical field [0001] The present application belongs to the field of instrument testing, and further relates to a testing machine for testing battery packs. Background technique [0002] With the increasingly serious energy crisis and environmental pollution problems, electric vehicles have gained opportunities for rapid development. High and low temperature testing of battery packs is widely used in the industry. However, due to the constraints of existing refrigeration technology, the current routine use of high and low temperature testing machines for battery packs can only use external heat to control the temperature. Defects in the existing external heat control: 1. The external heat control method needs to generate heat by consuming additional electric energy to achieve a balance with the cooling capacity, so as to achieve the purpose of temperature control; and in order to achieve the purpose of temperature control, the heating power needs to be Much larger than th...
