Abstract

The present invention discloses a battery temperature feature test method, device and system. The system comprises: a battery heater connected with the battery and configured for heating the battery; a data collection unit connected with the battery and configured to collect the temperature parameters and the electrical parameters of the battery; and a control terminal connected with the battery heater and the data collection unit and configured to send a control instruction for controlling heating to the battery heater and determine the temperature features of the battery according to the temperature parameters and the electrical parameters. The battery temperature feature test method, device and system solve the technical problem that the temperature features of the power battery cannot be accurately understand in the prior art.

Description

technical field [0001] The invention relates to the field of testing, in particular to a battery temperature characteristic testing method, device and system. Background technique [0002] The power battery is the power source of the electric vehicle, and the performance of the power battery directly affects the performance of the electric vehicle. The temperature characteristics of lithium-ion power batteries make them vulnerable to environmental conditions. High or low temperatures will have an impact on battery life, charge and discharge time, charge and discharge capacity, and battery safety. Therefore, it is necessary to accurately understand the power battery temperature characteristics. [0003] For the technical problem of being unable to accurately understand the temperature characteristics of the power battery in the related art, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a batter...
