Description

A kind of battery cell monitoring and balancing unit mounting structure
Technical field
This utility model is related to electric mechanical field, specially a kind of battery cell monitoring and balancing unit mounting structure.
Background technology
With developing rapidly for electric vehicle, requirement more and more higher of the country to lithium-ion battery energy, and battery management System is exactly the core of lithium ion battery.
BCU is battery cell monitoring and balancing unit, can be with the voltage of precise acquisition each battery core and temperature, when battery core occurred Temperature, overvoltage, under-voltage meeting and alarm, take corresponding protective measure.
At present, on market, BCU majorities are all to adopt to be encapsulated with can or plastic casing, by box body installing hole, Gu Be scheduled on the support of Battery case, battery core surface is locked to wire harness and terminal to realize collection.Such traditional mounting means Easily there is terminal loosening, the internal resistance increase of collection wire harness affects acquisition precision, and the layout of wire harness is complicated, affects tidiness, battery The weight of casing increases, and structure space layout is also restrained.
Therefore, the mounting means of BCU affects the weight and knot of precision, safeguard protection and the Battery case of the collection of battery Conformational space.
Utility model content
The purpose of this utility model is:A kind of battery cell monitoring and balancing unit mounting structure are provided, prior art knot is solved The problem of safety, cleaning and accuracy in structure.
The technical scheme for realizing above-mentioned purpose is:A kind of battery cell monitoring and balancing unit mounting structure, it is characterised in that bag Include
One battery cell monitoring and balance assembling printed circuit board (PCB), are provided with multiple vias or pad, the position of the via or pad The collection point on correspondence battery core surface;
One temperature inductor, is directly locked in battery core surface with balance assembling printed circuit board (PCB) with the battery cell monitoring;The electricity Cell monitoring assembles the voltage acquisition point of printed circuit board (PCB) with balance and temperature sensor is directly contacted with by the via or pad The battery core surface;
Wherein, the position of the via or pad is wrapped corresponding to battery cell monitoring and the collection point of balance assembling printed circuit board (PCB) Include voltage acquisition point and temperature acquisition point.
Further, each battery cell monitoring is assembled in each series electrical in set of cells with balance assembling printed circuit board (PCB) The battery core collection point of pond module.
Further, the battery cell monitoring is integrated with IC chip with balance assembling printed circuit board (PCB).
The utility model has the advantages that:Battery cell monitoring of the present utility model and balancing unit mounting structure, it is not necessary to box body Encapsulation;Via or the pad directly contact collection point of printed circuit board (PCB) are assembled using battery cell monitoring and balance, it is not necessary to use line Beam and collection adapter conduct indirectly, and high precision, stability are improved;Save the weight and arrangement space of Battery case;Avoid Traditional collection wire harness, length are uneven, it is impossible to which the shortcoming of unified wire harness standard, succinct wire harness optimize battery system cloth Office;When avoiding traditional wiring, wire harness insulation cortex is clipped broken by battery core and brings potential safety hazard.Safeguard protection performance is improved, short circuit When, battery cell monitoring is easier tilting with the Copper Foil of balance assembling printed circuit board (PCB) and blows, and wire harness then needs very high temperature Can disconnect;The Material Costs such as wire harness, adapter and terminal are saved, while simplifying production technology.
Description of the drawings
