Embodiment Construction
[0026] The present invention will be described in detail below with reference to the drawings and embodiments.
[0027] The pure electric vehicle energy consumption tester based on the single-chip microcomputer control of the present invention mainly includes CAN controller (SJ1000 module), CAN bus driver (TJA1050T module) and microprocessor (51 series single-chip microcomputer). The energy consumption meter is connected to the vehicle through hard-wire CAN network, the energy consumption meter system collects information such as voltage, current and mileage from the BMS module and VCU controller in the vehicle CAN bus, and calculates the power consumption of the vehicle during the driving process after the calculation of the microprocessor algorithm And the power consumption per unit distance of the vehicle (energy consumption), and the calculated power consumption and mileage information are displayed on the LCD display through the single-chip display module (LCD1602), which is ...

The invention provides a pure electric vehicle energy consumption tester and system based on a single chip microcomputer. The energy consumption test can be simply, conveniently, safely and reliably realized. The energy consumption tester comprises a single chip microcomputer, a CAN controller, a CAN bus driver, a display screen and a power supply circuit; the CAN controller is connected to the CAN bus driver through a serial data output line (TxD) and a serial data input line (RxD); the CAN bus driver is provided with a bus terminal CANH and a CANL with differential receiving and sending capacities and for connecting a vehicle CAN bus network, thereby acquiring the current voltage, the current and the mileage information of the vehicle, and then the current voltage, the current and the mileage information are provided for the single chip microcomputer through the CAN controller; the single chip microcomputer computes the electricity consumption in the driving process and the electricity consumption of the unit mileage (the electricity consumption of per mile) according to the current voltage, the current and the mileage information of the vehicle, and dynamically displays the specific numerical values on a display screen.
Description
Technical field [0001] The invention relates to the field of new energy pure electric vehicles, in particular to a pure electric vehicle energy consumption tester. Background technique [0002] With the introduction of a series of national policies on traditional fuel vehicle emissions restrictions and encouraging the development of new energy vehicles, at present, domestic new energy vehicles are already in a rapid development process, and the market share is increasing year by year. [0003] With the gradual entry of new energy vehicles into the market, vehicle reliability and energy consumption have attracted attention from end customers and operators. Especially for profit-oriented pure electric commercial vehicles, energy consumption has attracted much attention. At present, in the economic test of pure electric vehicle products, the test cycle of vehicle energy consumption parameters is longer and the test process is more complicated. [0004] CAN is an ISO internationally st...
