The main functions of the lithium battery protection board

The principle of the lithium battery protection board is very simple, and it is also simple to make, but it must be cheap, guarantee quality, and make money. It's not simple anymore. Customer requirements should be very clear, down to component model, process requirements, voltage requirements, current requirements, output port connection, load, etc. Because you may not be able to make money because of the extra few cents per IC or the extra link in a certain process. Let's take a look at the basic knowledge you need to know to make a lithium battery protection board.

Basic functions of lithium battery protection board:

1. Main technical parameters:

1. Overload protection voltagees (depending on the battery cell material used by the other party) Determined or requested by the customer)

2. Actual battery voltage for overcharging (based on the cell material used by the other party or requested by the customer)

3. Overcurrent protection voltage (see Depends on customer requirements. If customer does not need it, use company standard)

4. Overdischarge protection voltage (select the chip solution according to the solution required by the customer). )

5. Excessive discharge Restore voltage?

6. Self-consumption in normal operation

7. Self-consumption current in standby state (static operation current)

8. Short circuit protection time

9. Single cell overload voltage

10.? 2. Main components and processes used in battery protection boards

AC materialsrtes: PCB boards, fiberglass boards, flexible circuit materials for mobile phones, tablets, digital computers, etc. Flex board materials are more expensive and usually require a certain quantity; the process is divided into: immersion gold, gold plating, nickel plating, tin spray coating, submerged tin, among which the submerged gold plating process is the most complex and the cost is slightly more high: Colors are generally divided into: green oil, black oil, butter. The thickness of the plate is generally: 0.4mm, 0.6mm, 0.8mm, 1mm, 1.2mm.

FPC boards and battery protection boards are generally single-sided boards, and double-sided boards are also used. However, from a cost perspective, various manufacturers have now opted for single-sided panels, with generality. thickness of 0.1mm.

PCB board and FPC board, F boardPC has the highest cost, so many manufacturers try not to make FPC boards and use PCB boards instead. -------Flexible boards are available between 0.5 yuan and 3 yuan. The price varies according to different requirements.

Is it safe to use 2000w motor with lithium battery with 50% current limit?

The circuit diagram is as follows:

Working principle:

When the battery voltage is between 2.5V and 4, 3 V, pins 1 and 3 of the DW01 both output a high level (equal to the supply voltage), and the voltage of the second pin is 0 V. At this time, the voltage of pins 1 and 3 of the DW01 will be added to pins 5 and 4 of the 8205A respectively. The two electronic switches of the 8205A are in a conducting state because their G pole is connected to the voltage of the DW01, i.e. , both All electrical switchesronics are onState. At this time, the negative electrode of the battery is directly connected to the P terminal of the protection board, and the protection board has voltage output.

Detailed information

Main functions: overcharge protection function, overdischarge protection function, short circuit protection function, overcurrent protection function, overheat protection function, equalization protection function.

Interface definition: The charging port and discharge port of the board are independent of each other and share the positive electrode B- is the negative electrode connected to the battery, C- is the negative electrode. of the charging port; P- is the negative electrode of the discharge port; pads B, P and C are all through-hole type, and the pad hole diameter is 3mm for each battery charge detection interface;was released as a DC pin holder.

Parameter description: Configuration of maximum operating current and overcurrent protection current value, unit: A (5/8, 8/15, 10/20, 12/25, 15 /30, 20/40, 25 /35, 30/50, 35/60, 50/80, 80/100), special overcurrent values ​​can be customized according to customer requirements.

It is not safe whether a 2000W motor is equipped with a lithium battery with a current limit of 50. There are two settings for the protection board current of lithium battery, direct current and overcurrent protection. If 50A refers to continuous battery, there is no problem. If 50A refers to excessive protection current, the battery can be protected when starting. The motor starting current is large, so it is better to use a protection board (batterie) with great overcurrent protection. It is recommended that the protection current be greater than 100 A.
