Embodiment
[0024] Such as figure 1 As shown, the combined vehicle battery system includes a battery pack composed of single cells. Each single cell in the battery pack is connected to the motor through a power bus to provide electric energy for the electric vehicle, and then convert it into kinetic energy for output to Electric vehicle chassis; each single battery is also connected to the battery management system of the electric vehicle through the bus, and a position sensor connected to the battery management system is also provided at the installation place of each single battery.
[0025] In this embodiment, each battery includes a control chip, a relay connected to the control chip, a voltage monitoring module, and a power detection module. The relay is connected to the motor and is controlled by the control chip to open / close. The photoelectric communication interface of the battery is connected with the battery management system, and each single battery is connected with the motor...

The invention discloses a combined vehicle battery system and an implementation method thereof. The system comprises a battery pack formed by battery cells. Each battery cell in the battery pack is connected with a motor respectively. Each battery cell in the battery pack is also connected with a battery management system respectively. Each battery cell comprises a control chip, a relay, and an electronic quantity detection module, wherein the relay and the electronic quantity detection module are respectively connected with the control chip. The relay is connected with the motor and is controlled by the control chip to be switched on / off. The control chip is connected with the battery management system. The battery pack provided by the invention can be applied to electric vehicles of different watt levels, wherein the power and the energy can be flexibly increased or decreased. Meanwhile, the unified management of battery cells is realized, and battery cells can be maintained by professional companies and rented by users according to the actual application amount. Moreover, battery cells can be quickly replaced by users according to the electronic quantities of battery cells, so that battery cells are convenient in maintenance. Furthermore, each battery cell is ensured to completely run out of power, so that the resource waste is avoided.
Description
technical field [0001] The invention relates to a combined automobile battery system and belongs to the field of battery management. Background technique [0002] With environmental protection being concerned by countries all over the world. How to use electric vehicles in large quantities and reduce the pollution emitted by vehicles has become one of the focuses of technological development. [0003] Due to the different applications of electric vehicles, the design power ranges from 1Kw to 300Kw, and the usage methods are also very different. Of course, the requirements for batteries are very different. At present, according to different requirements, electric vehicle manufacturers will design different battery packs, which are costly and inefficient; the ownership of batteries is dispersed, and the cost of recycling is high. Contents of the invention [0004] The purpose of the present invention is to provide a combined automobile battery system, which mainly solves t...
