How to change the bucket seat of an electric vehicle to add a lithium battery

Introduction How to modify the bucket seat of an electric vehicle and add a lithium battery? An electric vehicle can modify the bucket seat and add a lithium battery in this way: there is no need to use two air switches, and just one. a double pole thrower can be used

How to change the bucket seat of an electric vehicle to add a lithium battery

Electric vehicles can be modified in this way to add a lithium battery to the bucket seat: there is no need to use two air switches and only one single-pole dual starter can be used. The knife is connected to a motor and other electrical devices, and the two terminals are connected to a set of batteries respectively. Move it to the left to use the original battery and move it to the right to use the spare battery. It is very simple. You add two extra wires to the original two wires that go into the motor. Install a circuit breaker on one of the original battery output wires, and the other does the same. During the battery disassembly process, check the quality of all connections, check whether the safety seat, charging plug and electric vehicle lithium battery connection wire are normal and reliable, and tighten alllithium battery electric bike connectors. . Those that need to be replaced should be replaced, and their reliability should be carefully checked, and those that are unreliable should be replaced.

How to install two sets of lithium batteries in a battery car

No, if you want to convert a lead-acid electric car to a lithium electric car, you just need to replace the charger, battery, battery compartment and match the battery voltage. Wait.

1. First of all, if you want to convert a lead-acid electric vehicle to a lithium-ion electric vehicle, the first thing you need to change is the charger. Since the internal resistance of lead-acid batteries is large, the output voltage of general chargers is relatively high, and many chargers have pulse charging functions. If you continue to use such chargersWhen charging lithium batteries, they will be overcharged. Before switching to a lithium electric vehicle, you must first replace the charger with a lithium electric vehicle charger.

2. Second, if lead-acid electric vehicles are to be converted to lithium electric vehicles, the battery voltage must match. To put it simply, if it is a 48V lead-acid battery, it should also be replaced with a 48V lithium battery. Of course, if the electric vehicle battery has a short lifespan, the capacity can also be increased appropriately. For example, if the original 20 Ah lead acid battery is used, it can be replaced with a 32 Ah lithium battery, provided the voltage is respected. remains unchanged.

3. Additionally, if a lead-acid electric vehicle is to be converted to a lithium-ion electric vehicle, the battery compartment must alsomay be replaced. Generally speaking, lead-acid batteries with the same voltage are larger than lithium batteries. If the battery compartment is not replaced, there will be obvious shaking after inserting the lithium battery. Therefore, users should replace the battery compartment with a suitable compartment.

4. Finally, if you want to convert lead-acid electric vehicles to lithium electric vehicles, you also need to choose the battery carefully. Why do you say that? Although the market is currently flooded with different types of lithium batteries for electric vehicles, from a practical point of view, many lithium batteries are of poor quality or pose certain safety risks. Therefore, when users choose lithium batteries, they should try to choose professional brand batteries, so that the quality is betterx guarantee.

5. In short, if you want to convert a lead-acid electric vehicle to a lithium electric vehicle, you just need to replace the charger, battery, battery compartment and match the battery voltage. Although technically speaking, lead-acid electric vehicles can be converted to lithium-ion electric vehicles, from a practical point of view it is generally not recommended to do this yourself, you should instead ask a maintenance technician to help you install it. Since lithium batteries are relatively unstable, private modifications may be associated with safety risks.

An electric vehicle uses two sets of batteries at the same time. Simply connect the two sets of batteries in parallel.

Configure the charger specifications based on the total capacity of the charger. two sets of batteries. Use a large charger at the same timetime.Manage two sets of batteries

For example: It used to be a 60V/20AH battery set equipped with a 60V/20AH charger, and now a 60V/20AH battery set is added. the batteries are directly connected in parallel, using a 60V/40Ah charger to charge both sets of batteries.

Data extension:

Electric vehicle battery performance:

1. Lead-acid battery (gel lead-acid battery), Cheap cost and stable performance, most electric vehicles on the market use this type of battery.

2. Lithium-ion battery (often called lithium battery) has a higher cost, but has large specific energy, high specific power, low self-discharge, no memory effect, good cycle characteristics and operating temperature. Range ; no environmental pollution and other benefits

3. The Crystal Ge batteryl has high cost and stable performance. There are not many electric vehicles using this type of battery on the market, and only a few companies are equipped with them. with these high performance batteries, the batteries have the highest safety factor. The advantage of much longer service life than the first two types of batteries and the advantage of self-healing function also constitutes the leading position in the industry. The advantage is that lead acid batteries do not have them, and the disadvantages. Delamination of lead-acid batteries can be avoided.

Types of electric vehicle batteries:

Primary batteries: those that are discarded after use and cannot be reused, such as carbon-zinc batteries, alkaline batteries, mercury batteries and lithium batteries. .

Secondary batteries: rechargeable and reusable, such as: rechargeable nickel-cadmium batteries, secondary batteriesnickel-metal hydride batteries, rechargeable lithium batteries, lead-acid batteries, solar cells, crystalline gel batteries and lithium iron phosphate. batteries.
