An electric vehicle uses two sets of batteries at the same time. Simply connect both sets of batteries in parallel.
Configure the charger specifications based on the total capacity of both sets of batteries. . Use a big charger at the same time. Manage two sets of batteries.
For example: It used to be a 60V/20AH battery set equipped with a 60V/20AH charger, and now it is a 60V set. /20AH batteries are added. The two sets of batteries are directly connected in parallel, using a 60V/40AH charger to charge both sets of batteries.

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. Crystal Gel battery 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: thosewhich are thrown away 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: nickel-cadmium rechargeable batteries, nickel-metal hydride rechargeable batteries, lithium rechargeable batteries, lead-acid batteries, solar cells, crystalline gel and lithium batteries iron phosphate. batteries.
