A method of estimating remaining battery power in electric vehicles is provided. The method uses coulometric detection method to obtain remaining battery power and uses an open voltage method to modify the coulometric detection method when modified conditions are met as well as different battery characteristics and conditions when in use. The remaining battery power in electric vehicles can conduct a dispersion degree detection at every stage and when a detection value is larger than a preset value, a self-adjusting mechanism will be activated to modify the battery power. When the battery is charged for a longer period of time, a regression method is used to establish a modified equation to increase precision of estimating remaining battery power.

A battery assembling device has two brackets and an assembling unit. The brackets abut each other and can be securely mounted around two battery units. The assembling unit has a quick-release housing and two clamps. The quick-release housing has two electrode holes. The clamps are respectively mounted in the electrode holes and each clamp has two opposite threaded inner surfaces. The battery units can be bundled by the brackets in advance to form regular battery modules. Because the assembling unit is easily and quickly connected with the battery modules, the assembling of a cell of an electrical vehicle is greatly convenient and fast.

A measuring device for measuring insulation resistance of an electric vehicle includes a measuring unit, a voltage detecting unit, and a control unit. The measuring unit includes a first tap, a second tap, a switch, and a measuring resistor. The first tap is to be electrically coupled to a high potential side of a high voltage system. The second tap is to be electrically coupled to a ground side of a low voltage system. The switch and the measuring resistor are connected in series between the first tap and the second tap. The voltage detecting unit is for detecting a voltage formed between the first tap and the second tap. The control unit is operable for controlling ON and OFF states of the switch, and is configured to determine the high potential insulation resistance and the low potential insulation resistance after operating the switch in the ON and OFF states.
