Electric van truck battery pack control system and method

Abstract

The invention discloses an electric van truck battery pack control system and method. The system comprises a battery pack control system, a vehicular monitoring system, a motor controller, a display instrument, a vehicular charger, a total negative relay, a DC / DC relay and an insulation monitoring unit, wherein the vehicular monitoring system, the motor controller, the display instrument and the vehicular charger are respectively connected with the battery pack control system. The battery pack control system comprises a battery pack control system main module and a slave control module which are connected through a CAN (controller area network) bus. The total negative relay, the DC / DC relay and the insulation monitoring unit are respectively connected with the battery pack control system, and the insulation monitoring unit is arranged inside a battery box. The vehicular monitoring system comprises a primary alarm unit and a secondary alarm unit.

Description

technical field [0001] The invention is applied to the field of pure electric vehicle battery packs, and in particular relates to a battery pack control system and method for electric vans. Background technique [0002] As the environmental pollution is becoming more and more serious, the country continues to introduce new energy-saving and emission-reduction policies. Pure electric vans are gradually occupying short-distance transportation due to their pollution-free, zero-emission, low-noise, high-efficiency operation, easy maintenance and strong support from national policies. , the market of urban logistics and transportation, and the life of the power battery pack is short and the replacement cost is high, which restricts the development of pure electric vans. While people are constantly improving the performance of the battery pack itself, they are also constantly researching and developing the battery pack control system. , to give full play to the performance of the ...
